Plastic angles can be cut, fixed and drilled easily. For fitting, many applications use self adhesive tape, which we can also supply. Equal plastic angles have legs of equal length and a 90 degree corner. The edges are square unless shown otherwise, and equal angle descriptions refer to the internal dimensions of the angle. Our Heavy Duty plastic angles are square internally, making them fit well, but with rounding on the external corner and legs, making them popular for nursing homes, lift lobbies or other areas where high impact collisions occur regularly.
