Compatibility Notice
Verify the original bracket model, left- or right-hand orientation, door material, panel thickness, roller-stem diameter, track size, cable-end design, mounting-hole arrangement, side-flange profile, and available clearance before ordering. Matching only the RBB-75 name does not guarantee compatibility with every residential garage door.
Not a Safe-T-Bracket: The standard RBB-75 is a conventional bottom bracket and should not be confused with Clopay or Ideal Door SRBB-75 Safe-T-Bracket models. Safe-T-Bracket components use a different safety-oriented design and different part numbers.
Extreme-Tension Safety Warning: The lifting cable attached to a bottom bracket is under extreme spring tension, even when the garage door is fully open. Never loosen, remove, cut, or adjust a bottom bracket while the cable or spring system is under tension. Sudden cable release can cause severe injury, death, or property damage. Replacement should be completed by a qualified garage door technician.
