Choosing the Correct Hardware

Extension spring systems use several interconnected components, and seemingly similar parts may have different dimensions, attachment methods, or load requirements.

Before ordering, compare the replacement part with your existing hardware and verify:

• Pulley diameter and style

• Cable routing

• Spring attachment method

• Door height and width

• Track configuration

• Hook, clip, fork, or eye-bolt dimensions

• Existing mounting arrangement

For pulley replacement, inspect both the pulley wheel and bearing or bushing condition. Worn pulleys can create cable drag, noise, uneven door movement, and premature cable wear.

Extension Spring System Safety

Garage door extension springs and lift cables can store significant mechanical energy. Components connected to the spring or cable system should not be removed while under tension.

Use properly rated replacement hardware and confirm that all cables, pulleys, springs, attachment points, and safety containment components are installed correctly before operating the door.

Professional installation is recommended whenever spring-system tension or lift cables must be disconnected.
