The weld-on prison hinge is made for heavy doors in locations such as prisons, x-ray rooms, detention centers, and jails. These double and triple weight steel hinges are tamper-resistant, built with a welded pin that is impossible to remove. Whether you're installing a new door or replacing faulty or old hinges, these will last for years to come.

Weld-on prison hinges are designed with tampering in mind. These options feature a hinge pin that's solid steel welded at both ends. Because of this, removing the hinge pin to break down the door simply can't happen. The weld-on prison hinge also features two concealed ball bearing assemblies with hardened raceways, as well as welded and machined rolled knuckles. The hinge is not swagged, so it cannot be mortise installed. The lubrication area is located in the barrel of the hinge.

Frequently Asked Questions

How long does it take to get my hardware once it's been ordered?

I have a hinge that I am trying to replace but I need help identifying it. Can you help?

Yes! Please click here to visit our Hinge Finder page.

Some of your hinges are sold by the each and some sell by the pair. What is the difference?

When the unit of measure says “pair” that means two hinges. Usually you need one pair of hinges per door. When the unit of measure says “each” that means one hinge. You would usually order 2 “each” hinges per door.

I want to replace my hinges. How do I make sure the screw holes on the new hinge match the screw holes on the old hinge so I do not have to redrill the holes?

Unfortunately, hinge manufacturers have never standardized the location of their screw hole patterns. Every manufacturer puts their screw holes in a slightly different place. This means that when you replace hinges you will almost certainly have to do some filling and redrilling. The exception to this is Architectural door hinges which are built to a standardized template for each size hinge.
