The finding
The federal garage door opener safety rule always follows UL 325, never leads it. Congress wrote it into law in 1990 (Public Law 101-608 § 203).
CPSC made it 16 CFR Part 1211 in 1992, then amended it in 1997, 2000, 2007, 2016, 2018 and 2024. Each change adopted a UL 325 revision, 1 to 63 months later (retrieved 2026-09-06).
What did we find?
Public Law 101-608 § 203 made a private trade standard’s entrapment-protection rules “a consumer product safety rule issued by the Consumer Product Safety Commission.” Entrapment protection means the opener must stop and reverse instead of trapping a person under the door.
The rule became 16 CFR Part 1211 on December 21, 1992 (57 FR 60455). Amendments followed in 1997, 2000, 2007, 2016, 2018 and March 14, 2024 (89 FR 18538). That is seven CPSC rulemakings in all.
Underwriters Laboratories revises UL 325 on its own schedule. Section 203(b) requires CPSC to adopt “any additional entrapment protection requirements” UL adds. The federal rule has never once led.
Where both dates exist: about 26 months in 2000, roughly 63 months in 2007, about six weeks in 2016, about 14 months in 2018 and about 10 months in 2024.
What does this page claim, and what doesn’t it?
A timeline like this is easy to over-read, so here are its limits first.
It does not judge whether any opener is safe. It records what the federal rule has required, and when, so you can check claims against the original text.
ecfr.gov and federalregister.gov sent every request we made to unblock.federalregister.gov instead of the document. That included an eCFR address an earlier brief for this site listed as working. We used govinfo.gov copies instead and say so at each citation.
CPSC’s own 2015 history summary describes the 1997 amendment (62 FR 46667) in one line. We found no fuller public account and did not invent one.
Two sources gave the 2000 final rule’s start page as 70656 and 70657. One is probably an error somewhere before us. We did not work out which.
Direct fetches of federalregister.gov and the govinfo.gov detail page both failed (a 404, or a bare title with no text). Our 2024 dates and figures come from a web search of a copy of the same document. We flag that weaker method.
It is a paid standard. Every UL 325 edition or revision date here comes from a CPSC rulemaking describing it, never from the standard’s own text.
When did each federal rule change? Eight documents, 34 years
The 1990 law and the seven rulemakings that followed, in date order. Each is sourced to the document itself or the closest copy we could reach.
November 16, 1990
Congress passes Public Law 101-608 § 203Congress writes the rule into law. § 203(a): its requirements “shall be considered to be a consumer product safety rule issued by the Consumer Product Safety Commission.” Deadlines: January 1, 1991 for UL 325 third edition as revised May 4, 1988, and January 1, 1993 for “any additional entrapment protection requirements” UL adopts by then.
December 21, 1992
Rulemaking 1 of 7: the law becomes a regulation (57 FR 60455)CPSC copies Congress’s requirements into the Code of Federal Regulations for the first time, creating 16 CFR Part 1211. This is not CPSC making its own safety call. It is carrying out § 203(b)’s instruction to put the UL 325 third-edition entrapment rules into a binding federal rule.
September 4, 1997
Rulemaking 2 of 7: the first revision by choice (62 FR 46667)The first amendment made under CPSC’s ongoing § 203(b) power to follow UL 325, rather than under a fixed deadline. CPSC’s own 2015 history summary describes it only as a revision of the rule. We found no fuller public account of what changed, and we say so rather than guess.
November 27, 2000
Rulemaking 3 of 7: the Fourth Edition catches up (65 FR 70656/70657)Adopts UL 325 Fourth Edition (January 1, 1995) as revised September 18, 1998: about 26 months after UL’s revision. A proposed rule came first, on June 14, 2000 (65 FR 37318). Two sources disagree on the start page, 70656 or 70657. We report both.
September 27, 2007
Rulemaking 4 of 7: the slowest catch-up (72 FR 54816)Adopts UL 325 Fifth Edition, published June 7, 2002: a gap of about five years and three months, the longest we could measure. It also adds UL 991, UL 1998 and UL 746C, plus the 1999 National Electrical Code. Proposed January 18, 2007 (72 FR 2217). Effective February 21, 2008.
April 7, 2016
Rulemaking 5 of 7: the fastest catch-up (81 FR 20224)Adopts a UL 325 Sixth Edition revision of February 24, 2016, six weeks later. CPSC calls it “minor and editorial in nature.” It set a 30-day effective date “because UL 325 Sixth Edition requirements were already in effect.” A proposed rule had been open since September 2, 2015 (80 FR 53036).
July 13, 2018
Rulemaking 6 of 7: the Seventh Edition (83 FR 32569)Adopts UL 325 Seventh Edition, published May 2017: a gap of about 14 months. Adds another circuit-testing method, more edge-sensor test figures and remote-monitoring rules for unattended operation. Issued as a direct final rule, effective September 11, 2018 unless serious objections arrived by August 13, 2018. None did.
March 14, 2024
Rulemaking 7 of 7, the most recent (89 FR 18538)UL told CPSC on May 19, 2023 about new entrapment-protection testing changes to the Seventh Edition. CPSC approved adopting them in June 2023. The direct final rule was published March 14, 2024, effective May 13, 2024: about ten months from UL’s notice.
Why does the federal rule always follow UL?
Because Congress built it that way. Read the dates in order and one thing stands out: CPSC has never started a change to what entrapment protection technically requires. Every amendment after 1992 catches federal law up to a UL 325 revision UL had already made.
HyreGarage analysis: this describes the design, not a failure. Section 203(b) of Public Law 101-608 requires CPSC to adopt “any additional entrapment protection requirements” UL adds, unless the Commission finds that doing so would not serve the law’s purpose.
We found no rulemaking where CPSC made that finding and declined to follow UL. In practice, UL sets the technical content of a federal safety rule. UL is a private standards body funded by manufacturers and other stakeholders. CPSC’s rulemaking then turns that content into binding law.
The two procedures CPSC used show this. The 2000, 2007 and 2016 changes went through a proposed rule and public comment first. The 2018 and 2024 changes used a “direct final rule”: published as final unless serious objections arrive by a deadline.
CPSC uses the faster route when it expects no controversy. Nobody objects to codifying a standard the industry already follows. Between UL’s revision and CPSC’s rule, compliant manufacturers are usually already building to the new UL text.
CPSC said this out loud in 2016. It chose a 30-day effective date “because UL 325 Sixth Edition requirements were already in effect” in the trade. The April 2016 rule did not create a new requirement. It formally recognized one manufacturers had already adopted.
That likely explains why 2016 shows the shortest gap and 2007 the longest. In 2016, CPSC opened its own rulemaking (September 2, 2015) before UL finished revising, so it could move as soon as UL published.
In 2007, nothing we found suggests CPSC started work anywhere near UL’s 2002 publication date. The five-year gap is the visible cost. One device this record created is the second sensor, usually a pair of photo-eyes. See how those sensors get bypassed or misaligned.
How long does CPSC take to adopt a new UL 325 edition?
Anywhere from about a month to 63 months, averaging about 23. Five rulemakings give both a UL 325 revision date and a federal rule date. HyreGarage computed each gap. As far as we found, no one had put these side by side before.
| CPSC rulemaking | UL 325 event | Federal codification | Gap |
|---|---|---|---|
| 65 FR 70656/70657 (2000) | UL 325 revised 18 Sep 1998 | codified 27 Nov 2000 | 26 months |
| 72 FR 54816 (2007) | UL 325 5th ed. published 7 Jun 2002 | codified 27 Sep 2007 | 63 months |
| 81 FR 20224 (2016) | UL 325 6th ed. revised 24 Feb 2016 | codified 7 Apr 2016 | 1 months |
| 83 FR 32569 (2018) | UL 325 7th ed. published May 2017 | codified 13 Jul 2018 | 14 months |
| 89 FR 18538 (2024) | UL notified CPSC 19 May 2023 | codified 14 Mar 2024 | 10 months |
HyreGarage computation from the dates in each rulemaking’s own background section, retrieved 2026-09-06. Average across these five: about 23 months. The 1992 rule is left out because it carried out a fixed deadline set by Congress. We could not retrieve both dates for 1997.
What did each rulemaking add?
Short summaries, where we could confirm them, each taken from the rulemaking’s own background section.
1992: the founding rule
Copies the law’s UL 325 Third Edition entrapment rules into 16 CFR Part 1211 for the first time. It carries out a specific instruction from Congress, not CPSC’s own technical judgment.
2000: the Fourth Edition and referenced standards
Adopts UL 325 Fourth Edition as revised September 18, 1998, and brings in DASMA and other referenced industry standards alongside it.
2007: more standards join the rule
Adopts UL 325 Fifth Edition (2002). Adds UL 991, UL 1998 (software in entrapment-protection devices), UL 746C and the 1999 National Electrical Code as referenced standards, effective February 21, 2008.
2016: new door types and one reference section
Covers horizontally sliding doors and combination sectional/rigid one-piece overhead doors. Creates § 1211.14 (unattended operation) and § 1211.15 (combination systems). Gathers the referenced standards into a new Subpart D.
2018: testing detail
Adds an alternative electronic-circuit test method (Supplement SA), more edge-sensor test figures (6A through 6I), remote-monitoring rules for unattended operation, and revised secondary-protection rules for doors moving sideways and up and down.
2024: the latest, and still narrow
Reflects UL’s May 19, 2023 notice of further entrapment-protection testing changes: two revisions adding new tests and several clarifying edits. CPSC approved it in June 2023; the rule was final on March 14, 2024.
Docket CPSC-2015-0025 has carried this standard’s public comments since at least the 2015 rulemaking.
What do the terms mean?
- UL 325
- Underwriters Laboratories’ safety standard for door, drapery, gate, louver and window operators. First published 1973; now in its Seventh Edition (2017) with later revisions. It is a private, paid standard, not a law. 16 CFR 1211 adopts it by reference.
- 16 CFR Part 1211
- The binding federal rule, “Safety Standard for Automatic Residential Garage Door Operators.” First codified December 21, 1992 and amended six times since. This is the enforceable law; UL 325 is the private standard it follows.
- Entrapment protection
- The safety features that stop a closing garage door from trapping a person: the door must reverse when it meets an obstruction, backed up by a second device such as photo-eyes.
- Direct final rule
- A CPSC procedure that publishes a rule as already final, effective on a set date unless serious objections arrive first. Used for the 2018 and 2024 amendments. It signals CPSC expected no real controversy.
- Incorporation by reference
- The legal method that makes a specific dated edition of UL 325 (and other named standards) a federal requirement without copying its text into the CFR.
- Federal Register citation
- A citation like “81 FR 20224” means Federal Register volume 81, starting on page 20224. The govinfo.gov copy we used files documents by issue date, so several sources below have date-based addresses.
How can you check this yourself?
Plan around the access problem we hit if you want to check a specific rule.
Both sent every request we made to an anti-bot challenge page. If you hit the same wall, it is an access control on the government side. The document has not moved.
Search “govinfo.gov” plus the Federal Register citation (for example “govinfo.gov 81 FR 20224”). Or browse a yearly Code of Federal Regulations edition, such as CFR-2023-title16-vol2, for the current text.
Every CPSC final rule opens with a background section naming the UL edition it adopts and the earlier rules it amends. That is more reliable than any summary, including this one.
We did this for the 2000 rule’s page number and still could not settle 70656 against 70657. If you can, we would like to know which is right.
It has exactly the same force as a rule that went through full notice and comment. CPSC simply used the faster route because it expected no serious objection.
What couldn’t we verify?
The full text of UL 325, any edition. It is a paid standard. Every UL date, edition number and change described here comes from a CPSC rulemaking’s background section, never from the standard itself.
What changed in the 1997 rulemaking. Our best source, a CPSC history filing, describes 62 FR 46667 in one line with no technical detail. We did not fill that with a guess. If you need the specifics, read the Federal Register document directly.
Which start page is right for the 2000 rule. 70656 or 70657. We got both from sources we otherwise rely on and did not decide between them.
A directly fetched copy of the 2024 rule’s full text. Two direct fetches failed (a 404 and a title-only page). Our 2024 details come from a web search summarizing a copy of the document. That is weaker than the direct reads behind every other entry, and we say so.
One thing we chose not to do: extend the gap chart back to 1992. That rule carried out a fixed deadline from Congress, not CPSC responding to a UL revision. Mixing it in would blur a real difference into a false average.
For how this record plays out in American homes, see how many openers predate the federal safety standard and what federal injury data shows.

Primary-source research, data analysis and fact checking
We are not a garage door company. We read the agency file, the code record, the standards document or the public register ourselves, compute the figure from it, and publish it with the source and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. Our own company records cover ten states; nothing national is ever derived from them.
- 10
- states our own company records cover — and the limit of any claim made from them
- 3,901
- garage door companies in the store
- 457
- license records verified against a state board
- 0
- national claims made from a ten-state store
How this desk works
- Primary sources only. Injury counts come from CPSC. Housing counts come from the Census file, not from a summary of it. Code history comes from the building commission that adopted the code. We do not cite an article that cites a source; we retrieve the source and do the arithmetic ourselves.
- Every figure carries its retrieval date. Registers change, datasets are revised and codes are amended. A number without the date it was read cannot be checked, so every study states one.
- Fact, calculation and analysis are labeled apart. A quote is a quote, a HyreGarage computation says so, and an interpretation says “HyreGarage analysis”. Presenting our reading of a dataset as something the agency stated would be the easiest way to lose the only thing this desk is for.
- Limitations go above the fold. If a figure is an upper bound, a bracket, or an association rather than a cause, that is said before the figure is quoted rather than in a footnote underneath it.
- No DIY instructions for spring, cable or track work. Those components hold enough stored energy to cause serious injury, and CPSC records the consequences. We describe what has failed and what a competent repair involves; we do not tell you how to do it.
