Swedish-made drainage cover for mounting on plastic drainage pipes. Manufactured from high-strength 3 mm Domex steel, electro-galvanized with a yellow chromate conversion coating, and finished with a UV-resistant green polyester powder coating.
The underside of the grate features reinforcements for increased load-bearing capacity (not applicable to the 200 mm version), which also serve to center the grate. Four countersunk screw holes are provided for attachment; stainless steel screws (5.5 x 100 mm) are included.
