Heavy-Duty Bi-Fold Design

The AHDGH-057 is specifically designed for bi-fold door applications requiring two sections to pivot smoothly in relation to one another.

Its equal-leaf design provides balanced attachment on both door sections while the geared mechanism helps maintain synchronized movement throughout the opening and closing cycle.

This makes the hinge well suited for demanding commercial bi-fold applications where conventional butt hinges may experience excessive wear or alignment problems.

Continuous Geared Construction

Instead of concentrating the door load at a few individual hinge points, the continuous geared design distributes the load along the full length of the hinge.

Benefits include:

• Improved load distribution

• Reduced localized stress

• Better door alignment

• Reduced sagging

• Smooth movement

• Improved durability in frequently used openings

• Reduced wear compared with multiple individual hinge points

Up to 450 lb Door Capacity

Always verify the complete door weight, dimensions, mounting conditions, and application before ordering.

Security Molding

The AHDGH-057 incorporates security molding to provide additional protection around the hinge assembly.

This feature helps resist:

• Tampering

• Unwanted access around the hinge edge

It is particularly useful in commercial and institutional environments where durability and security are important.
