BHMA Grade 1 | Heavy-Duty Continuous Geared Hinge | Full Surface Mount | American Made

The Vector Hinge Co. AHDGH-210 Full Surface Geared Hinge is an American Made, BHMA Grade 1 continuous hinge engineered for demanding commercial doors requiring superior strength, alignment, and long-term performance.

Its full-surface mounting configuration makes the AHDGH-210 especially well suited for retrofit and replacement applications where mortising the door and frame is not practical.

By supporting the door along nearly its entire height, the continuous geared design distributes weight more evenly than conventional butt hinges, helping reduce door sag, frame stress, hinge failure, and alignment problems in high-traffic commercial openings.

Heavy-Duty Full Surface Design

Benefits include:

• Reduced door sag

• Improved door alignment

• Better load distribution

• Reduced frame stress

• Reduced door reinforcement stress

• Less recurring hinge maintenance

• Smooth, consistent operation

• Improved durability in high-traffic openings
