Apparatus and method for forming a recess in a door frame

An adjustable door keep jig for use in cutting a recess for a door keep in a door frame, the door keep jig comprising:

• a spine extending in a first direction;
• a first body element and a second body element each being connected to the spine and each extending away from the spine in a second direction, the first and second body elements being spaced apart from one another;
• a first leg slidably connected to the first body element and extending from the first body element toward the second body element in the first direction, the first leg being slidably adjustable relative to the first body element in both the first and second directions;
• and
• a second leg slidably connected to the second body element and extending from the second body element toward the first body element in the first direction, the second leg being slidably adjustable relative to the second body element in both the first and second directions,
• wherein the spine, the first and second body elements, and the first and second legs define therebetween an opening, the opening providing a guide for a cutting tool to form the recess in a surface of the door frame when the door keep jig is placed against the surface of the door frame within which the recess is to be cut.
