The bottom bracket is attached to the bottom of your double garage door. It holds the bottom roller on one side and, on the other, a pin that attaches your torsion cable to the bottom of the door.
Every double door requires two bottom brackets, one on the left and one on the right.
Our bottom brackets are 1.6mm galvanised steel.
Double door bottom brackets are longer than single door bottom brackets. For single door bottom brackets, click here.
