The Dockmate Piling Post Fender is designed to fasten directly onto a dock piling post fitting securely against the piling to provide maximum protection of the boat and dock. The fender has a curved back that allows it to flush mount tightly against the curved surface of the piling post that helps lock it into position. Eight angled, recessed mounting points create a pocket for the fasteners keeping them tucked away after installation to avoid contact with the boat. This inflatable, air-filled fender is constructed of tough Marine Grade, UV protected, PVC that will stay flexible in the elements and provide long lasting protection. Although designed to fit piling posts it can also be mounted to square pilings and other flat surfaces on the dock that are at least 5 1/2" wide. It can be mounted vertically or horizontally onto the side of your dock. There are 8 Stainless Steel Fender washers and 8 Stainless Steel screws included with the fender for mounting. Measures 48" long x 5 1/2" wide x 4" thick. Dockmate 48" Piling Post Fender
