Adams Rite B1923 Full Surface Reinforcing Pivot with 3/4" Offset for 4-1/2" Butt Hinges

Heavy-Duty Door Reinforcement Solution

The Adams Rite B1923 Reinforcing Pivot provides a cost-effective and durable solution for sagging or misaligned doors by transferring load from failed hinges to more structurally sound fastener points. Constructed from heavy-duty 3/16" cold-rolled steel with zinc-plated finish, this full-surface reinforcing pivot features a 3/4" offset specifically designed for 4-1/2" wide butt hinges. Tested for 1,500,000 cycles and supporting door weights up to 300 lbs, the B1923 extends service life of commercial door openings by shifting stress from the top hinge to screws mounted in shear.
