16 CFR 1211.6 - General Entrapment Protection Requirements for Garage Door Operators

Every residential garage door opener sold in the United States since 1991 must meet federal entrapment-protection requirements. Section 1211.6 is the rule that sets the floor: one safety system is not enough. You need two.

What this regulation says

16 CFR 1211.6 establishes the two-device requirement for all residential vertical-moving garage door operators:

"(a) An operator of a residential garage door shall incorporate inherent primary entrapment protection that complies with the requirements as specified in § 1211.7.

(b) An operator of a vertically moving residential garage door shall also comply with one of the following: (1) The controls shall require constant pressure... (2) The operator shall be designed to accommodate one external entrapment protection device... (3) For combination sectional overhead systems only, the operator shall include inherent secondary entrapment protection..."

The two required protection types are:

1. Inherent primary entrapment protection (covered in detail by 16 CFR 1211.7): the door must reverse within 2 seconds of contacting any obstruction while closing. This is the mechanism most people call "auto-reverse."

2. Secondary entrapment protection (covered in detail by 16 CFR 1211.8): a separate system that prevents the door from contacting an obstruction in the first place. The most common form is a photoelectric sensor (photo-eye) mounted across the door opening near floor level. An edge sensor on the bottom of the door is the alternative.

Section 1211.6(e) adds a durability requirement: any mechanical switch or relay used in the entrapment system must withstand 100,000 cycles of operation before testing for compliance.

Section 1211.6(f) states what must happen if the entrapment protection circuitry fails: the operator must become inoperative or move the door to within 1 foot of the fully open position. The system must fail safe.

When it applies

16 CFR Part 1211 applies to all residential garage door operators manufactured for sale in the U.S. It does not apply to commercial operators or to manually-operated doors.

Common real-world situations where 1211.6 is the key reference:

• Buying a new opener: any operator sold retail or installed by a contractor must meet 1211.6. If a quote includes an opener, ask for the UL 325 listing number. UL 325 compliance is how manufacturers demonstrate conformance to this CPSC rule.
• Photo-eye replacement: if a sensor is damaged or missing, reinstalling it is not optional. An operator missing its secondary device fails 1211.6 and is a code violation.
• Older openers (pre-1993): openers manufactured before the 1991 amendments went into effect may have only one protection type, or none. The CPSC recommends replacing these.
• Denver permit inspections: when a building permit is pulled for a garage door replacement that includes an opener, the AHJ inspector verifies that the installed system meets current safety standards, including dual entrapment protection.

What this means for you

Two working safety systems are the legal minimum. If your opener's auto-reverse passes the board test (place a 2x4 flat on the floor and close the door; it should reverse on contact) but the photo-eye is broken or removed, the opener is not compliant.

Test both systems monthly. For the auto-reverse: place a 1.5-inch board flat on the floor and close the door. It should reverse when the bottom seal touches the board. For the photo-eye: wave your foot through the beam while the door is closing. It should reverse immediately.

After any opener installation or service, both tests should be part of the technician's sign-off. G Brothers technicians verify both on every job.

16 CFR Part 1211 applies to residential garage door operators only. Commercial operators are governed by UL 325 requirements for monitored external entrapment devices, which differ from the residential standard.
