What to know before buying

Listing details to confirm

The latch plate is described as unremovable. Check that this and the listed latch backset and door-thickness range suit your installation. The listing also uses inconsistent product wording, calling the set a door knob in the title while its feature details describe a lever, and gives a 1"L x 1"W product dimension that does not clarify the full handle dimensions. Confirm the intended hardware type and overall measurements in the selected listing.
