This is a 9 inch VGBA Square Wave Anti-Entrapment Suction Outlet Cover with vented riser ring and mud frame in white. The 9 inch Wave Anti-Entrapment covers easily and safely retrofit to a 9 inch square 3/4 inch deep frame. They are designed to replace standard 9 inch square covers that have a 8-1/4 inch center-to-center screw measurement with 3/4 inch deep existing frame. This Wave cover works with AquaStar 9 inch standard models and American/Pentair models with 3/4 inch deep existing frames and a four screw hole pattern.
The Square Wave main drain covers are made of superior UV-resistant engineered polymers. They include 316 stainless steel screws. They are Certified, Listed, and Labeled in conformance with APSP/ANSI/ICC-16 2017 and NSF/ANSI/CAN 50 standards. This is an update of the 2008 VGB certification. The Trademarked VGBA compliance button easily identifies this VGBA 2017 complaint cover from on deck and underwater.
The AquaStar VGBA Series of Anti-Entrapment Suction Outlets and Drains are compliant with the Virginia Graeme-Baker Pool and Spa Safety Act (ASME/ANSI A112.19.8-2007).
