Will these work on a mobile home?

Hi JW330, In most cases, no. Standard residential locksets like this one are generally not compatible with the specific requirements of mobile home doors for two main reasons: Backset Distance: Mobile home doors typically require a 2-3/8 inch backset (the distance from the edge of the door to the center of the knob hole), but many older mobile home doors use a specialized 5-inch backset or a very shallow 2-inch backset. While this Grip-Tight set features an adjustable latch (2-3/8 in. to 2-3/4 in.), it may not reach the specific positioning of a pre-drilled mobile home door. Door Thickness: Standard residential doors are 1-3/8 in. to 1-4/4 in. thick. Mobile home doors are often much thinner (frequently 1 inch to 1-1/8 inches). If the door is too thin, the lock cylinders will not tighten against the door face, leaving the hardware loose and non-functional.
