Abstract: A folding pen with two handle sections and a body is disclosed where the handle sections are attached to the body at hinges and rotate between two positions. The first closed position may cover the body and the second open position may reveal the body providing a writing implement with a pen point and a handle.

Abstract: A hinged spreader board of a pre-set length with shaped ends is pivoted open inside a frame to mate with the inside faces of the sides of a frame and maintain the sides apart by the length of the board while attaching the frame to a wall. Additional hinged sections of pre-set lengths allow the spreader board to be opened to various lengths to accommodate frames of different widths. The frame spreader boards fold up for storage.

Abstract: A square channel shaped template of ultra-thin rigid plastic, metal or other material has one or more mating configurations of pencil-point-size marking holes in the two opposing faces of the channel. Each configuration of marking holes matches a configuration of screw holes on a door fixture or door hardware to be mounted on a door. Each configuration of holes may be distinguished by a visible line through the marking holes of each configuration. The template straddles an edge of a door at a measured distance along the edge and fits on the edge with the door closed in a door frame for marking either one or both sides of the door with a mating configuration of marks on the door for drilling.
