Some styles of Kwikset levers are handed, usually due to a curved design. There are left-handed levers and right-handed levers. To determine the appropriate handing for your door, look at the hinges from the exterior side of the door. If the hinges are on the left, you require a left-handed lever. If the hinges are on the right, you need a right-handed lever.
Kwikset
locksets provide automatic adjustment to door thickness within the ranges
specified for each product. Most standard doors have a thickness of 1-3/4”,
however, it is necessary to measure this dimension to determine what your
needs are for your door hardware. Please refer to the technical
specifications of each of our products to make sure your door and the door
hardware you choose is compatible.
The
backset is the measurement between the edge of the door to the center of the
hole drilled for the lock. Kwikset provides many types of latches, some of
which are adjustable from 2-3/8” to 2-3/4”. To determine backset, measure
the distance from the center of the hole drilled in the face of the door, to
the door edge.
