• SBB-2 Sure Stop Low-Cable-Tension Safety Bottom Brackets for 2-Inch Track – Pair

  The SBB-2 Sure Stop is a garage door safety bottom bracket system designed to help reduce the risk of a sectional door free-falling if a lifting cable breaks, becomes disconnected, or loses tension.

  When cable tension drops below the required level, the safety mechanism engages the garage door track to help stop uncontrolled downward movement. This makes the SBB-2 particularly useful for heavier residential, commercial, and industrial sectional garage doors where cable failure could create a serious safety hazard.

  Designed for garage doors using standard 2-inch track, these brackets can be installed on standard-lift, high-lift, and vertical-lift door systems. The product is supplied as a matched pair for the left and right sides of one garage door.

  Important Compatibility Information

  Before ordering, confirm that your door uses 2-inch track and falls within the specified door-weight range. The SBB-2 requires the correct cable size, cable routing, track spacing, panel clearance, and installation geometry to operate properly.

  This product is not a universal replacement for every standard bottom bracket. It is a specialized safety device and may require modifications to the lifting cables or bottom-section mounting arrangement.

  Professional Installation Required

  Garage door bottom brackets are directly connected to lifting cables that remain under extreme spring tension. Removing or improperly installing a bottom bracket can cause the cable, bracket, or spring system to release suddenly, resulting in serious injury, death, or property damage.

  Installation, adjustment, testing, and replacement should be performed only by a trained garage door technician familiar with cable-break safety devices.
