Buying Guide

Material and durability

Choose UV‑resistant vinyl or 100% polyethylene for long-term exposure to sun, salt, and moisture; these materials resist cracking and degradation

Mounting and fit

Confirm piling cap diameter or corner bumper dimensions to match your dock posts and corners for secure, gap‑free coverage

Protection type

Pick piling caps for post protection and corner/inflatable fenders for edge and hull impact cushioning depending on where your boat contacts the dock

Installation and maintenance

Look for simple slip‑on or fasten designs and materials that are easy to rinse and inspect to reduce upkeep time

Bird and wildlife considerations

Solid piling caps can deter perching and nesting on posts, while rounded or smooth surfaces reduce accumulation of debris and droppings
