Edge Trims are the most common type of edge protectors around. They are generally used as protection on sharp edges of signboards, wire slots and work furniture. Edge trims are made of either TPE (Thermoplastic Elastomer) or PVC (Polyvinyl Chloride). Edge Trims have an internal aluminum core (A5052 for TPE and A3004 for PVC). They have gripping tongues for easy installation. Edge trims are extremely easy to install and require no special tools other than your hands.
