About Hinges

Wraparound Full-Length Entry Door Hinges

One leaf mounts around the edge of the door for a secure hold, while the other mounts to the frame.

Tamper-Resistant Full-Length Entry Door Hinges

A snap-on cover protects these hinges from tampering and creates a finished appearance.

Full-Length Entry Door Hinges

Longer than other entry door hinges, these piano-style hinges run the entire length of doors for strength and durability.

Piano Hinges without Holes

These hinges are made of metal.

Mil. Spec. Piano Hinges without Holes

Choose these hinges for their adherence to strict military standards for material and construction.

Plastic Piano Hinges without Holes

Plastic hinges are a lightweight alternative to metal hinges and provide smooth, silent operation.

Carbon Fiber Piano Hinges without Holes

Made of carbon fiber, these hinges are as strong as aluminum yet lighter in weight. All have leaves that are connected by a strip of flexible Kevlar instead of a pin.

Piano Hinges with Holes

These hinges are made of metal.

Piano Hinges with Slots

Mounting slots allow door alignment adjustments during and after hinge installation.

Slip-On Piano Hinges

No need for drilling holes or welding, slip these hinges onto panel and door edges for a secure fit.

Tight-Clearance Piano Hinges

The leaves of these hinges almost touch when the door is closed. They are often used in electrical enclosures for a tight seal.

Extra-Clearance Piano Hinges

When the door is closed, the distance between the leaves is larger than the pin diameter, creating an offset to accommodate a gasket or trim.
