Optional accessories


CHI slide lock
Manual push-up doors furnished with interior slide bolt locks with padlock provision standard.

Chain hoist doors operated doors furnished with chain hoist keeper suitable for padlocking

Inertia brakes

CHI brakes
Located on the drive shaft, these breaks sense a sudden increase in rpm and apply immediate braking to prevent curtain free-fall.

Sloping bottom bar

Designed for those applications where the floor or sill of the opening is sloped due to the building being built on an incline (think San Francisco or Pittsburgh). This option provides a secure closure to the opening even without the traditional 90 degree squared openings at the floor level.

Super-imposed or Door-behind-a-door

The C.H.I. superimposed rolling steel door is two doors sharing a single pair of head plates and wall angles. The door is designed for applications that require maximum security and an environmental barrier some of the time and allow airflow and security at other times. A number of different door and grille combinations are possible. These superimposed door designs are preferred in many commercial, industrial, defense, and food service applications.
