PYI manufactures a Floor fastener designed and engineered to secure floorboards and/or lock hinged panels. Made out of 316L stainless steel, they will not corrode, discolor with age or damage the wood surface (an age old problem in securing floorboards). The Floor Anchor safely holds 500 lbs per unit and has a 1000 lb breaking load. The PYI Floor Anchors meet ISAF (formerly ORL) requirements for offshore boats (Category 1-2003). The opening mechanism is a simple bayonet style; with ¼ turn lock and release that will not loosen with age. It can be opened or closed by either a coin or a flat head screwdriver. The 11-FA1-00 Floor Anchor is suitable for 1" to 1 ¼” thick floorboards. This kit is for a Pack of 12.
