This pack of corner guards contains 20 pieces, with each piece measuring approximately 48 in. long and 1-1/8 in. wide, providing coverage for all kinds of vulnerable corners and edges in a space. The product is not pre-drilled; it can be secured either with adhesive for a hassle-free setup or with screws via drilling for enhanced stability. Please note that adhesive is not included in the package. Crafted from rigid vinyl plastic, the corner guards boast excellent corrosion and aging resistance, and are easy to clean and maintain. They can withstand damage from wheelchair impacts, pet scratches and other potential hazards, effectively protecting walls, furniture and other facilities. Installation is flexible and straightforward—double-sided tape, adhesive or small nails are all workable options, with drilling installation being more suitable for high-traffic areas. Featuring a low-profile design, these corner guards can be painted to match the appearance of walls, furniture, fireplaces, staircases and other scenarios, remaining nearly invisible after finishing. They can also cover water stains and worn areas, creating a smooth, burr-free surface. Compatible with multiple materials including wood, metal, ceramic tiles and walls with peeling paint, the corner guards offer reliable protection for both internal and external corners.
