Board corner joints

Our PVC corner joint sections, which are also known as board corner joints, are designed to fit into boards which are positioned at a 90 degree angle. As well as providing support, board corner joints can hide and protect cut ends of boards and panels. Materials that can be pushed into the profile include foamex, plywood, glass and other commonly used materials.

Our universal corner joints are suitable to be used as both internal and external corner joints.
