|Precision end bearing plate
For 650 lb (250 kg) doors and over, to provide stronger support for the opening system of the door.
|Double hinges||For very wide and very heavy doors, 1 000 lb (453 kg) and over|
|11-gauge hinges||Steel (Light woodgrain finish)|
|12-gauge continuous angle||Provides stronger attachment of the tracks on the wall.|
|1 1⁄4” (30 mm) solid shaft||Provides more strength to the spring system.|
|Bridge strut||Ensures better resistance to wind load.|
|Safety bottom brackets||For a safer door system. If the lifting cables break, these brackets stop the fall of the door.|
|Tension bridge reinforcement||For very wide doors (18’ 3” wide and over), prevent warping of the steel door sections, meaning the curving of sections which can be caused by indoor and outdoor temperature differences.|
|Precision rollers||Machined steel: recommended for heavy doors and dusty environments.
Black nylon: made of rigid plastic, they reduce the noise of the door in motion.
Rubber: ensure smooth rolling and are recommended to reduce the noise of the door in motion (ideal for condo or apartment).
NB-SS: with a stainless stem, ideal for car washes.
|C-shaped or bumper springs||For a softer stop, they are recommended for all manually-operated doors with a high-lift track or a full vertical track.|
|Pusher springs||For a softer stop, they are recommended for all manually-operated doors with a high-lift track or a full vertical track.|
|C-shaped or bumper springs||Highly recommended for large size doors with a standard lift with a Jackshaft opener installed beside the door. They ensure the good tautness of the lifting cables when the door is operating.|
|Chain hoist||For easier closing and opening of a door operated manually.|
|"Z" or "L“ style track guards||Protect the tracks in high-traffic areas (ex.: forklifts).|
|High-cycle springs||Recommended for intense uses of more then 50 operation cycles per day. Vary from 25,000 to 200,000 cycles.|
