Door & Grille Operators

Trolley-type operators

use rails to create a path for the door to travel. A traveling device is connected to the door, and a chain is connected from the operator to the traveler. When activated, the operator moves the chain, in turn pulling the traveler (and the door) up along its path.

MG Operators

are used where there is a heavy door to operate, many cycles per hour, or a combination of both.

Warranty

PowerMaster warrants all door operators to be free of defects in materials and workmanship for a period of two (2) years from date of manufacture provided that product has been registered.

Hoist and Jackshaft operators

are mounted to the side of the door or the front of the hood in the case of a grille application. Hoist operators have emergency hand chain which assists in operating the door manually. Jackshaft operators have a disconnect lever, which disengages the unit so that it can be lifted manually.

Slide Door Operators

are used where there is a need to partition off an area or passageway, such as a fire partition, freezer door, or warehouse area.

Powder Coated

All of our door operators have a black, powder coat finish.
