Commercial Door Operators
The operator is the part of the door that actually does the work. We size it to the door and the traffic, and we keep it running.
Commercial Door Operators in Sacramento & Northern California
A commercial door operator has to match the door it moves and the number of times a day it moves it. A jackshaft operator mounts beside the barrel or torsion shaft of a rolling or sectional door. A trolley operator pulls a sectional door along its horizontal track. A hoist operator adds a chain hoist for manual operation when power is out. High-cycle and continuous-duty operators use heavier gearing and motors for busy docks and parking garages. Automatic sliding and swing door operators are their own category with sensors and safety requirements. Put the wrong operator on a door and it fails early; put the right one on and it runs for years.
Guardian Door LLC installs, repairs, and replaces commercial door operators of every type across Sacramento and Northern California — motors, gearboxes, control boards, limit switches, clutches and brakes, chain and belt drives, wall stations, radio controls, photo eyes, sensing edges, and timers. We also convert manual doors to motorized operation and upgrade under-rated operators on high-cycle openings.
