Cable Pulleys

Cable Pulleys for Extension Spring Doors

Garage door pulleys are super important for your extension spring garage door system to work smoothly. We've carefully chosen each pulley in our selection to make sure they're of great quality, durable, and reliable.

Garage doors are made up of many different parts, and one of the most essential components is the garage door pulley. These pulleys are crucial when you have extension springs that help lift the door. They're installed above the horizontal tracks on either side of the door. When the door is closed, the extension springs stretch out, and the door cable runs from the base of the garage door, up over the stationary pulley, and loops back around the garage door cable pulley attached to the end of the extension spring. As you raise the door, the extension springs pull on these cables, lifting the door while the springs relax.

However, if a cable pulley splits or breaks, the door may not open or get stuck halfway due to a jammed cable. That's where our collection of sturdy garage door pulleys comes in. We stock the two most common sizes of extension spring cable pulleys: 3" cable pulley and 4" cable pulley. Each of our garage door cable pulleys is heavy-duty with 10-ball bearings, able to handle up to 10,000 cycles of operation. They'll give you reliable performance that lasts a long time.

When you're replacing a broken pulley, it's a good idea to check all the other pulleys as well since they're probably around the same age. We recommend replacing all the pulleys at once to ensure everything operates smoothly and harmoniously. This advice applies to extension springs and cables too, considering how they all work together.
