Protect commercial doors, frames, hinges, and surrounding surfaces with this Adjustable Crash Chain, designed to help limit excessive opening on out-swinging commercial doors.

Adjustable from approximately 25" to 33", the chain can be configured to suit a variety of commercial door applications. When properly installed, it helps prevent the door from being forced beyond the desired opening angle by wind, heavy use, or accidental impact.

Adjustable 25"–33" Design

The adjustable chain length allows the restraint to be configured for the desired door opening angle.

• Door widths

• Frame configurations

• Opening angles

• Mounting locations

• Commercial entrance applications

Always adjust the chain so it limits excessive travel without interfering with required door operation or egress.

Helps Protect Door Hardware

Out-swinging doors can be exposed to significant force from:

• Wind

• Heavy pedestrian traffic

• Forceful opening

• Delivery carts

• Equipment movement

• Everyday commercial use

A properly installed crash chain helps absorb and limit this movement before the door reaches a position that could damage the opening.

It can help reduce stress on:

• Hinges

• Continuous hinges

• Door closers

• Door frames

• Storefront framing

• Lock hardware

• Door faces
