DON JO 30-1/2" Heavy Duty Crash Chain

Protect your commercial exterior doors and hardware from high-wind damage and over-extension with the Don-Jo HDCC Heavy Duty Crash Chain. Engineered to absorb violent impacts, this commercial-grade door stop limits the door's swing radius to prevent costly damage to hinges, door closers, frames, and adjacent walls.

Key Features

• Heavy-Duty Impact Absorption: Built with rugged steel links and heavy-weight springs engineered to cushion the abrupt stop of heavy commercial wood or hollow metal doors.

• Protective Vinyl Sleeve: Encased in a durable gray vinyl cover that prevents the chain from scratching or marring the door surface and dampens clanking noises during operation.

• ANSI Certified Security: Conforms to strict industrial hardware standards with ANSI/BHMA A156.3 LB2231 approval for high-frequency, severe-service applications.

• Commercial Finish Options: Available in Satin Chrome (626) and Duronodic Dark Bronze (DU) to seamlessly match existing storefront or perimeter entrance aesthetics.
