Abstract: A versatile system for producing channel letter coil of superior reflectivity and durability is described that includes providing a readily formable substrate. A first reflective material is disposed upon a first surface of the substrate. A second reflective material is disposed upon the first reflective material. An aesthetic material is disposed upon a second surface of the substrate. The entire substrate, with the reflective and aesthetic materials intact, is then rolled into a channel letter coil product, ready for immediate and efficient use in sign production.

Abstract: A door assembly for a recreational vehicle has a molded mounting frame and a molded flange. The mounting frame and the door have integral hinge pin lugs. Spring-loaded hinge pins are captured within the hinge pin lugs and allow the door to swing open or close. A latch secures the door assembly in a closed position. The door may be thermally insulated. The hinge pins may be stainless steel. The latch may be a locking mechanism. The door securely conceals the door frame fasteners when the door assembly is in the closed position. One hinge pin may be fixed to one hinge pin lug.
