Both finishes provide a clean commercial appearance and coordinate with common architectural door hardware.

Heavy-Duty Bi-Fold Configuration

The HDGH-057 is designed specifically for applications where two compatible door sections fold together during operation.

Its continuous geared construction provides a smooth pivot connection between the door panels while helping maintain consistent alignment.

This makes it an excellent alternative to multiple conventional hinges in demanding bi-fold applications.

Equal-Leaf Design

The equal-leaf configuration provides balanced mounting surfaces on both sides of the hinge.

This design is ideal for compatible bi-fold applications requiring:

• Balanced load distribution

• Consistent panel alignment

• Full-height support

• Smooth synchronized movement

• Heavy-duty performance

Continuous Geared Construction

Traditional butt hinges concentrate the load at several individual mounting points.

The HDGH-057 instead provides continuous support along the hinge length, helping:

• Distribute door weight

• Reduce localized stress

• Minimize panel sag

• Maintain consistent alignment

• Reduce wear at individual pivot points

• Improve operation on frequently used doors

Heavy-Duty Capacity

The HDGH-057 is designed to support compatible door applications weighing up to:

450 lb

Actual suitability depends on the complete door system, installation conditions, door dimensions, mounting structure, and hardware configuration.

Security Molding

Integrated security molding provides added protection around the hinge area.

This design helps reduce access to the hinge joint and adds protection against:

• Prying

• Tampering

• Abuse

• Impact in demanding commercial environments
