Kwikset 508 Interconnected Lock
Installation Requirements


Kwikset 508 Interconnected locks require a center to center bore spacing of 5-1/2" (See Fig. 1 below). Two holes 2 1/8" are required, one for the deadbolt mechanism and one for the lever. These two holes MUST be spaced 5 1/2" from center to center (see Fig. 1 below). Each hole is standard door prep (see Fig. 2 below).
If your door is already drilled and the two holes measure anything other than 5 1/2" from center to center, this model WILL NOT FIT your application.

If you have a modern door or you are buying an off-the-shelf door from a home center and it is drilled for a knob and deadbolt, most likely the spacing between the two holes will be 5 1/2" center to center. If you have not yet received your door contact the vendor and double check the specifications, some door and window millworks make their own rules and don't follow the door hardware industry standards.

You will be asked to verify that your hole dimensions as per Fig. 1 and Fig. 2 below at the time you place your order. Your order will not be shipped until this is confirmed.
This product is non-returnable.
