Genie 112631 Jackshaft Garage Door Operator 1/2 Hp 3 Phase

Product Description

The GENIE 112631 is a standard-duty jackshaft garage door operator head designed for commercial and industrial sectional door applications. It runs on a 3-phase power supply and delivers 1/2 HP of drive force to operate sectional doors up to 24 feet high. The unit mounts to the side of the door opening and drives the torsion shaft directly, keeping the ceiling clear of a traditional trolley rail. A built-in brake provides controlled stopping and holds the door in position when the motor is not running. Licensed door system installers typically handle installation on commercial properties.

This operator head is suited for standard-duty sectional door installations in commercial warehouses, loading docks, and light industrial facilities. It is engineered for use with sectional doors reaching a maximum height of 24 feet. The 3-phase motor configuration makes it appropriate for buildings with 3-phase electrical service. The jackshaft design is particularly useful where low headroom or ceiling obstructions make an overhead trolley-style operator impractical.

Key Features

• 1/2 HP 3-phase motor for standard-duty sectional door operation
• Jackshaft mounting drives the torsion shaft directly, freeing ceiling space
• Integrated brake provides controlled stops and holds door position at rest
• Powder-coated black finish for corrosion resistance in working environments
• Compatible with sectional doors up to 24 feet high

Compatibility

Designed for use with sectional doors reaching a maximum height of 24 feet. Verify torsion shaft diameter and tube size before installation to confirm mechanical compatibility with the jackshaft drive coupling.

Installation Notes

Installation should be performed by a qualified door systems technician or licensed electrician familiar with 3-phase wiring requirements and local electrical codes. Disconnect and lock out all power to the circuit before mounting or wiring the operator head. Secure the unit to the structural jamb or wall bracket per the manufacturer mounting instructions and verify torsion spring balance before cycling the door under power. Do not attempt to adjust the torsion spring system without proper spring winding tools and training.
