This Garage Door Bottom Bracket is the bracket at each lower corner of the door that anchors the lift cable and holds the bottom roller. A bottom bracket bolts to each lower corner of the bottom section. The lift cable loops onto it, and it carries the bottom roller in its roller holder, so it transfers the spring’s lifting force into the door.

Safety: This Part Works With Spring Tension
Parts of the counterbalance system are loaded by the springs whenever the door is closed.
- Never loosen bottom brackets, cable drums or lift cables on a closed door with wound springs. They hold the full spring tension; unwind the springs or have a technician do the work.
- Clamp the door in place before working on it.
- Replace one part at a time and keep hands clear of the drums and cables.
If you are not trained in garage door spring work, have a technician carry out the repair.
Signs It Needs Replacing
Corrosion at the bottom of the door eats into the bracket.
The corner was hit or the cable pulled it out of shape.
A worn cable at the bracket often means the bracket needs checking too.
Frequently Asked Questions
Why is a bottom bracket dangerous to replace?
The lift cable attached to it carries the full tension of the springs. Loosening it on a closed door with wound springs can release that tension violently. The springs must be unwound first, which is a job for a trained technician.
Do I need one or two?
The door has one at each lower corner. Order one per damaged bracket; if both are rusted, replace both.
How is it shipped?
It ships by FedEx, or you can collect it from our Sacramento or Santa Clara store. See our shipping policy for current rates and dispatch times.
