Abstract
Abstract A liner for use with a door edge guard and the assembly of the liner with the door edge guard and the door itself. The liner is characterized by three beads, at least one of which is located within the metallic door edge guard when assembled on the door. The liner is made primarily of a plastic material, but may include one or more reinforcing wires within the beads for enhanced strength advantageous during installation of the liner and edge guard on a sheet metal door edge.

Claim 1
Independent Claim
162 words
An improved edge guard and liner for a metal door edge guard of U-shaped cross-section, the liner being of the type comprised of a nonmetallic material intended to prevent metal-to-metal contact between the metal door edge guard and the sheet metal edge of a door received within the edge guard and the liner, the liner being adapted to be positioned between the edge guard and the door edge and being characterized by at least one bead extending along its length and a membrane connected to the bead, and in combination with a metal edge guard of U-shaped cross-section, the liner being within the edge guard and the bead being in contact with the interior surface of the edge guard, and with a sheet metal edge of a door received within the U-shaped liner, the membrane of the liner occupying less than the entire space between the interior surface of the edge guard and the door edge in the region adjacent the bead.
Claim 2
Dependent Claim
