GLOSSARY

Vancouver, BC

Knowing your decorative hardware terms is important when it comes to ordering our speciality products for your space. For your convenience and to ensure clarity, we have put together a collection of in-depth descriptions of the terms used within the industry that will assist you along the way.

 

Active Door 
This is the primary door, in a pair of doors that is used to enter and has operable door hardware installed.

American or U.S. Cylinders

Back-to-Back
This usually refers to independent door handles being mounted back to back from each other on both sides of the door leaf.

Backset
This is the length of the latch and the position of the lockset on to the door stile. It is the distance from the edge of the door to the center of the handle, knob, deadbolt or predrilled face bore. The standard backsets for a tubular lockset are 2 3/8” or 2 3/4” and for a mortise lockset are 2 1/2” or 2 3/4” in length.

Clavos
This is a decorative nail with a large head that are installed onto the surface of the door, usually in series.

Deadbolt
This is a heavy-duty tubular bolt that acts as the locking mechanism, operated by a thumb turn or key. It can be independent or integrated into an escutcheon plate and be accessed by either side in an entry function or only by one side in a patio function.

For example, a door with hinges on the right side is a right-handed door and a door with hinges on the left side is a left-handed door.
