1-Inch Two-Piece Split Shaft Collar for Garage Door Torsion Shafts

This 1-Inch Split Shaft Collar provides a secure clamping point on standard garage-door torsion shafts. Its two-piece design allows the collar to be installed around an existing shaft without sliding it over the end or removing cable drums, bearings or other shaft-mounted components.

The collar uses two clamping screws to apply even pressure around the shaft, helping retain bearings and other components while limiting unwanted axial movement.

Product Features

• Fits standard 1-inch-diameter shafts

• Two-piece split design

• Installs without access to the end of the shaft

• Two clamping screws included

• Strong steel construction

• Black protective finish

• Even clamping pressure around the shaft

• Suitable for residential and commercial garage-door systems

• Sold individually

Specifications

Common Applications

• Garage-door torsion shafts

• Bearing retention

• Cable-drum positioning

• Shaft-mounted component retention

• Jackshaft operator installations

• Commercial sectional-door assemblies

• Residential torsion assemblies

• Repair applications where the shaft cannot be removed

Compatibility

Designed for garage-door systems using:

• 1-inch hollow torsion tubes

• 1-inch solid torsion shafts

• Residential sectional-door counterbalance systems

• Commercial sectional-door shaft assemblies

• Compatible jackshaft operator installations

Measure the shaft’s outside diameter before ordering. This collar is designed for a 1-inch shaft and is not compatible with 1-1/4-inch shafts.

Split Collar Advantage

Unlike a solid set-screw collar that must slide over the end of a shaft, this two-piece collar separates into two halves. The halves can be positioned around an installed shaft and secured with the included clamping screws.

This design is especially useful when cable drums, bearings, springs or other components make the shaft end difficult to access.

Installation

Position both collar halves around the shaft and install the clamping screws. Tighten the screws gradually and evenly so the collar seats squarely and applies uniform pressure.

Do not use the collar as a substitute for a properly installed bearing, cable drum, spring cone, shaft coupler or structural shaft support.

Safety Notice

Garage-door torsion springs, cables, drums and shafts can remain under extreme tension. Release spring tension according to proper service procedures before removing or repositioning components in the counterbalance system.

Installation and adjustment should be performed by a qualified garage-door technician.
