What is Backset

If you dont have any hardware on your door, just measure from the edge of the door to the center of the bore hole (the large hole where the door knob assembly is mounted). Standard backsets are either a 2 3/8" backset, or 2 3/4? backset. The most common backset is 2 3/8? but 2 3/4" is also quite common - usually used on exterior doors. Sometimes it's easier to measure from the edge of the door to the highest point on the bore hole. If you don't order the correct backset, your latches will either be too long or too short and you will not be able to mount your door hardware. Some brands of door hardware like Schlage, Weiser, Kwikset, Sure-Loc and Weslock are shipped with adjustable backset latches which makes ordering easy. We generally only ask you for your backset on hardware that requires it.

If you already have door hardware mounted to your doors you can remove the hardware and measure as we have indicated above, but you don't need to. You can measure from the edge of the door to the center of the backplate behind the knob. See the picture to the left as an example. This particular door has a 2 3/8" backset.

Have a 5? Backset?

We have 5" backsets available for Schlage and Kwikset. You can order new knobs and levers with 5" backsets in those brands, but you would not be able to use their 5" backsets with other brands. You can order replacement 5" backsets by choosing one of the links below:

Have a 2 1/2? Backset and a box in your door instead of a standard latch? You need a mortise lock.

Have a 2" Backset? Your options are limited because not many manufacturers make a backset that small, but we can help. Check out the links below.
