Genie 112631 Jackshaft Garage Door Operator 1/2 Hp

Product Description

The GENIE 112631 is a 1/2 HP, three-phase jackshaft operator head designed for commercial and industrial rolling door applications. It mounts to the side of the door opening and drives the torsion shaft directly, eliminating the need for a trolley-style rail system. Built for standard-duty cycle use, the unit ships with an integrated brake that holds the door position when the motor is not energized. The powder-coated black housing measures 29.75 inches tall, 19 inches wide, and 14 inches deep, making it a compact solution for facilities where overhead clearance is limited.

This operator is rated for rolling doors up to 24 feet high, a specification that targets warehouse, loading dock, self-storage, and light-industrial door applications. The three-phase motor configuration suits facilities with three-phase power already present, such as manufacturing plants, distribution centers, and commercial garages. Installation is handled by a licensed electrician for the power wiring and a door systems technician for the mechanical side. It is not intended for residential sectional doors or single-phase residential circuits.

Key Features

• 1/2 HP three-phase motor suited for facilities with three-phase electrical service
• Jackshaft design mounts to the wall beside the door, preserving overhead clearance
• Integrated brake holds door position when power is not applied to the motor
• Rated for rolling doors up to 24 feet in height
• Powder-coated black finish for corrosion resistance in industrial environments
• Compact footprint at 29.75 inches x 19 inches x 14 inches

Compatibility

Designed for use with rolling doors up to 24 feet high. Intended for standard-duty commercial and industrial rolling door installations where a three-phase power supply is available. Confirm door weight, cycle rate, and torsion shaft diameter against the operator specifications before installation.

Installation Notes

Electrical connection to a three-phase supply must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Disconnect and lock out all power before beginning mechanical mounting or wiring. The torsion shaft must be properly balanced and the door spring tension set before the operator is engaged. Verify brake adjustment after installation to confirm the door holds position without drift.
