Lunmar Boat Lifts has a large selection of piling caps in stock, ready to ship. Piling caps prevent moisture from penetrating the core of your piling which, leads to rot. The cone shaped caps prevent birds from landing on your pilings, while the flat caps allow you to set something on top of the piling. Measure the diameter of your piling and round up. Piling caps come in 1/2“ sizes if needed. If your piling is 9 7/8 then order a 10”, if 10 1/8“ then order a 10 1/2”. Please contact a sales representative if you need assistance.
