Abstract
Abstract An edge guard comprises a generally U-shaped cross section with insulated beads formed at the outer marginal edges of the legs which apply the retention force to the door edge. The invention provides a construction which is self-retaining on different types of surfaces. The metallic material of the edge guard is 5052 H-23 aluminum.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
A self-retaining insulated metal edge guard comprising a metallic channel having a U-shaped cross section, a non-metallic covering extending around the exterior of the U-shaped cross section, inwardly turned beads at the ends of the U-shaped cross section, said covering extending around said beads so as to cover the inwardly facing surfaces of said beads, and in which the material of said metal is 5052 H-33 aluminum, said metallic channel adapted to apply the self-retention force via said beads through said covering on the inwardly facing surfaces of said beads.
Claim 2
Dependent Claim
