It’s serious business when an exterior commercial door won’t close. If this happens to a retail establishment or restaurant, somebody has to stay to ensure the security of the building until the door is repaired.
It’s not uncommon for the hinges on steel doors or glass and aluminum doors to fail. Many times these commercial doors use the traditional pin-and-barrel style hinge. The top hinge of a pin-and-barrel hinge system supports 70% of the door’s weight. While this may be fine in residential applications, commercial doors are heavy. It’s no surprise that the top of the door will eventually hit on the jamb and the door will not close with the constant use that commercial doors get every day!
We have the solution. Roton hinges – also known as a “continuous geared hinge” – distributes the weight of the door evenly from top to bottom. Also, the hinging mechanism is made up of two gears that mesh together, reducing lateral friction. The mounting plate itself is bolted through the door, as opposed to threaded screw holes that can wear.
The bottom line is, when you have Goffstown Lock and Key install a continuous geared hinge, it will be the last hinge you ever buy!
