U PROFILE FOR 4mm. AND 6mm. POLYCARBONATE. 2.10m LENGTH. With a length of 2.10m, equal to the width of the plate, it serves to close the alveoli of the plate. It can also be used as a termination on the side of the plate (3 units per side). It is a safe and easy-to-install system, it prevents the entry of water or dust. The profile is placed manually or with a rubber hammer so as not to damage it, with slight pressure. It fixes the plate and can be used to screw with self-drilling screws, fixing it to the wooden or metal structure that serves as a support. In our blog you can see the montage.
