Genie 112631 Jackshaft Garage Door Operator Head 1/2 Hp

Product Description

The GENIE 112631 is a 1/2 HP single-phase jackshaft operator head designed for commercial and residential sectional garage doors up to 24 feet high. Unlike trolley-style openers, a jackshaft operator mounts to the wall beside the door and drives the torsion shaft directly, freeing up ceiling space. This unit includes an integrated brake for controlled door stopping and is finished in powder-coated black for durability in shop, warehouse, and facility environments. It is sized for standard-duty applications and is installed by commercial door technicians or licensed contractors.

The 112631 is rated for sectional doors reaching a maximum height of 24 feet, making it well suited for high-bay commercial bays, loading docks, and large residential or light-commercial overhead door installations where ceiling-mounted operators are impractical. The jackshaft configuration keeps the operator out of the overhead travel path, improving usability in spaces with low clearance or obstructed ceilings. The included brake adds a mechanical stop function that is particularly important on tall, heavy door panels.

Compatibility

Designed for use with sectional doors reaching a maximum height of 24 feet. Verify torsion shaft diameter and door weight ratings before installation to confirm fitment with existing door hardware.

Installation Notes

Installation should be performed by a qualified commercial door technician or licensed contractor familiar with overhead door systems and local mechanical codes. Disconnect and lock out all power to the operator circuit before beginning any wiring or mounting work. The jackshaft head must be securely anchored to the wall framing at the appropriate height relative to the torsion shaft centerline. Do not attempt to operate the unit without first verifying that the brake and drive components are properly aligned and all fasteners are torqued to the door manufacturer's specifications.
