Garage Door 1" Shaft Coupler – Adjustable Center Torsion Shaft Coupler for 1" Keyed Shaft Systems

Adjustable

• Made in the USA
  

• Description

  The Garage Door 1" Shaft Coupler – Adjustable is a heavy-duty torsion shaft connector designed to join two 1-inch solid torsion shafts in commercial and residential overhead door systems. Built from durable cast or malleable iron construction, this adjustable coupler ensures secure torque transfer while allowing for minor alignment correction between shaft sections.

  This coupler is commonly used in center shaft applications where long torsion tube runs require multiple shaft sections or where field adjustments are needed during installation or repair. Its adjustable split-body design allows installers to properly align shafts, tighten securely, and maintain consistent rotational movement across the full door system.

  Engineered for reliability in high-cycle garage door environments, this coupler helps maintain smooth operation while reducing stress on bearings, drums, and other torsion system components.
