Heavy-Duty Continuous Geared Hinge | Limited Frame Full Surface | Security Molding | Up to 450 lb Doors

The Vector Hinge Co. AHDGH-157 Limited Frame Full Surface Geared Hinge is an American Made heavy-duty continuous hinge engineered for commercial openings where limited frame-face space, high traffic, and long-term durability are important.

Designed specifically for limited-frame full-surface applications, the AHDGH-157 requires only a 7/8" minimum frame face, making it an excellent solution for openings where a conventional full-surface continuous hinge may not fit.

The geared continuous design distributes door weight along the full height of the opening, helping reduce door sag, hinge-point stress, and recurring alignment problems. The integrated security molding adds protection while creating a clean, professional installation.

Limited Frame Application

The AHDGH-157 is specifically designed for openings with a limited amount of usable frame face.

With only 7/8" minimum frame face required, it provides a continuous-hinge solution for commercial frames where larger full-surface hinge profiles may not be suitable.

Security Molding

The integrated security molding helps protect the hinge area while providing a cleaner finished appearance.

This design is particularly useful for commercial and institutional doors where durability, security, and resistance to abuse are important.

Continuous Geared Hinge Benefits

A continuous geared hinge supports the door along nearly its entire height rather than concentrating the load at three or four conventional hinge points.

Benefits can include:

• Reduced door sag

• Improved door alignment

• Better load distribution

• Reduced stress on frame reinforcement

• Reduced stress on the door edge

• Smoother opening and closing

• Reduced recurring hinge maintenance

• Improved performance in high-traffic openings
