Door Hinges
(Click Here to Download .pdf)
Most people take door hinges for granted; we figure that when we purchase a door, the hinges on it will do the job. In most cases that statement is true, however there is a lot more to hinges than what you may think, especially commercial hinges. The variations are many, for example: the type of metal used (steel, brass, stainless steel) the size of the hinge (3”, 3.5”, 4”, etc.) & removability of the hinge pin and other factors.
Romtec specifies hinges for functionality, durability and value. Unless a custom hinge is specified by our customer, the standard hinge used in Romtec buildings is the 4.5” x 4.5” stainless steel commercial hinge manufactured by Bommer, Inc. The barrel of the hinge (this is the part that the pin is inserted into) has nylon bushings between the spots where the steel would touch each other. The bushings help eliminate wear and help seal lubricant inside the hinge.
Because the doors swing out, the hinge barrels are on the outside of the building, making the hinge pins accessible. Romtec has chosen to have two of the three hinges made with non-removable pins (NRP). This means that even if someone removes the center pin from one of the three hinges, the door will still function properly, and the person will not be able to gain access to the room.

An older man from the hills of Oregon, Chuck Guyer knows the things our younger generation doesn't. Reviewing engineering plans isn't a job you can give to any rookie Engineer, its a big responsibility. Chuck is responsible for building plans being correct, as well as product quality. Fueled by Golden Nugget ice cream bars and Fox News, Chuck sits alone at his desk all day long.
I understand, Chuck. I have been a drawings reviewer, design, construction, and shop, for twenty five years. (I have also specified finish hardware for twenty five years.) Being the guy with the red pen doesn’t make you a lot of friends. But, it’s easier to build from correct drawings!
