• Mounting positions

• Desired opening angles

Helps Protect Door Hardware

A crash chain acts as a mechanical restraint to help prevent a door from opening farther than intended.

This can help reduce damage to:

• Door hinges

• Continuous hinges

• Door closers

• Frames

• Wall surfaces

• Glass

• Storefront framing

• Locking hardware

It is especially useful on exterior openings where strong wind can force the door beyond its normal operating range.
