Tool
Lock Fit Checker
This answers a dimensional question and refuses to answer anything else. Given your measurements it says which shapes of lock could physically go in that door, and which of the 8 lock listings on this site state that they are one of those shapes.
It will not tell you that a specific lock fits your specific door, because nothing that has not seen your door can honestly say that. Where a measurement is missing or unusual it returns nothing and tells you what to measure again.
Door thickness
Backset, edge of door to center of bore
Bore in the face of the door
Which way does it swing, seen from outside?
Is there a deadbolt on it already?
Is the door yours to change?
Answer all six groups above. The result lists which shapes of lock are physically possible from those numbers, and which listings here state that they are that shape.
The rules it runs
- A shape is possible only when the door thickness is 1-3/8 in or 1-3/4 in. Anything thinner or thicker needs a specific kit and this tool returns nothing rather than guessing.
- A shape is possible only when the backset is 2-3/8 in or 2-3/4 in. No listing in this catalog states an adjustable backset, so any other measurement returns nothing and a line telling you to check with the manufacturer.
- A 2-1/8 in bore is treated as a drop-in replacement. A 1-1/2 in bore or no bore means a new hole has to be cut, which is drilling.
- If you rent and a new bore would be needed, every shape is blocked and a reversible alternative is offered instead. If you rent and no new bore is needed, shapes are shown but flagged as needing the landlord’s agreement in writing.
- Any measurement marked as not measured yet blocks every shape and appears in the measure-again list. The tool never fills in a value you did not give it.
- An outward-swinging door adds a note that no inward-only reinforcement device is an option, which does not change which locks fit.
- Where a deadbolt is already fitted, deadbolt shapes are described as a replacement. Where one is not, a line is added that a handle set or knob set is not a substitute for a deadbolt.
What each listing states about its shape
These are statements taken from the listings. They are not measurements of your door and not a claim that anything fits it.

What it does not know
- It does not know your door and cannot confirm that any specific lock fits it. Only the manufacturer specification for the exact model can do that.
- It does not check the frame, the strike pocket or whether the bolt would fully engage, which is where most of the value of a deadbolt actually is.
- It does not consider finish, handedness of a handle set, or whether the new lock covers the marks left by the old one.
- It has no view on whether a lock is any good. It answers a dimensional question and nothing else.
