Service Spring BB-7 Outside Hookup Bottom Bracket Pair – 2" Track, 11 Gauge
The Service Spring BB-7 Outside Hookup Bottom Bracket is designed for sectional garage doors using standard 2" track. Installed at the bottom corners of the door, the brackets provide the attachment point for the garage door lift cables and support the transfer of lifting force from the cable system to the door.
Constructed from heavy-duty 11-gauge steel, the BB-7 uses an outside-hookup configuration with a drilled pin for cable attachment. Brackets are supplied as a pair for the left and right sides of the garage door.

Installation & Safety
Garage door bottom brackets are connected directly to the lift cables and can be under substantial tension from the spring system.
Do not loosen, remove, or modify a bottom bracket while the lift cable or spring system is under tension.
Replacement should be performed by a qualified garage door technician using appropriate procedures and tools. Incorrect handling of bottom fixtures, cables, or springs can cause serious injury or property damage.
