Frequently Asked Questions
The most common commercial door hardware is the cylindrical lock. It’s easy to install in office environments and they are cheaper than other kinds of commercial door locks. They also come in a variety of styles and functions for different situations. A common office model features an exterior keyed lock with an interior push-button mechanism.
A commercial grade 1 lock refers to the American National Standards Institute (ANSI) grade of locking systems. There are 3 grades with 1 being the highest grade and 3 being the lowest. A commercial grade 1 lock must be able to withstand at least ten hits of 75 feet pounds of force and 1,000,000 open-close cycles.
BHMA stands for the Builders Hardware Manufacturers Association. They are the only organization accredited by ANSI to test locks, closers, exit devices, and other types of hardware for performance and standards.
The difference is in the name itself. A single-cylinder lock features keyed entry on the exterior of the lock and a thumbturn on the inside. A double-cylinder lock has keyed entry on both sides of the lock. A double-cylinder lock should be used in situations where the lock will be in close proximity to glass such as the front door of a business. This way, someone cannot break the glass and unlock the door by reaching inside the building.
Reversible locks can be adjusted to fit either left-handed or right-handed doors. Mortise locks can commonly be reversed, but you should check the model to make sure.
Backset is the distance from the edge of the door to the center of the borehole on the door. The standard backset in the United States is 2 ⅜” or 2 ¾”. Check your door lock’s specifications to determine its backset or check the manufacturer’s website.
