Commercial Full Mortise Hinges in Steel and Stainless Steel

PDQ commercial full mortise hinges carry the weight of a commercial door and keep it swinging and latching under daily traffic. The range covers plain bearing and 2 ball bearing standard weight hinges, 4 ball bearing heavy weight hinges, and self-closing spring hinges, in steel and stainless steel.

Hinge weight and bearing type follow the door's weight and traffic. Steel suits interior doors in non-corrosive environments, while stainless steel suits exterior doors and corrosive environments. Every PDQ hinge conforms to NFPA 80 and carries a 5-year limited warranty.

Frequently Asked Questions

How many hinges does a commercial door need?
A door up to 5' tall needs two hinges, plus one more for each additional 30" of height or part of it. That means three hinges on a standard 7' door and four on an 8' door.

What is the difference between ball bearing and plain bearing hinges?
Ball bearing hinges have hardened steel ball bearings between the knuckles, so the door turns with less friction and the hinge wears less. Plain bearing hinges pivot metal on metal with no bearings and suit low-traffic doors. PDQ recommends ball bearing hinges on any door with a closer.

What is a non-removable pin hinge?
A non-removable pin (NRP) hinge has a pin that cannot be tapped out while the door is closed, so the door cannot be lifted off by pulling the pins. It should be specified on out-swinging doors. PDQ includes a non-removable pin on every 2 and 4 ball bearing hinge.
