Floor Anchors are designed and engineered to secure floorboards or lock hinged panels. Available in either brass or 316L stainless steel, they will not corrode, discolor with age or damage the wood surface. These Floor Anchors meet ISAF requirements for offshore boats (category 2.03) and can safely hold 500lbs per unit. The opening mechanism is a simple bayonet style, with 1/4 turn lock and release that will not loosen with age. It can be opend or closed by either a coin or flat head screwdriver with all components permanently attached so you don’t have to worry about loose pieces dropping in the bilge. Suitable for 1/2″ to 3/4″ or 7/8″ to 1-1/4″ thick floorboards.
