Abstract: A frame-and-clip assembly utilized in the installation of a door frame to a compartment used for storage, baggage or the like, such as found in a recreational vehicle or other shell-like camper housing, although adaptable to compartments in other housings as well. The frame member includes first and second legs extending in opposite directions but joined by a spacer member between them, and a notch located in the corner region of the first leg and the spacer member. The second leg is adapted to engage the outer wall surface of a wall section forming the exterior boundary of the compartment. The clip gripping member comprises generally an upright member mounted on a base and extending over the length of the first leg, a barb on the base for attaching to the notch and a flange and lip for wrapping around the distal end of the first leg. A thinner cross-section in the base, adjacent the gripping member, facilitates the assembly.
