Corner guards, edge guards, and bumpers absorb and distribute forces from impacts to prevent damage to vulnerable corners in walkways and corridors. Self-adhesive corner guards have pre-installed adhesive strips for tool-free installation. Adhesive-ready corner guards install with separately available compatible adhesive. Screw-in corner guards install with screws through pre-drilled holes in the corner guards. Clip-on corner guards snap onto screw-in mounting strips. Bullnose corner guards have a radius profile instead of a 90 degree corner angle. Corner bumpers protect a narrow vertical portion of a corner. Edge guardsabsorb impacts on flat lips and edges to prevent damage and injuries.
