Slammer Marine
Slammer Marine piling fenders mount directly to dock pilings, posts, and fixed vertical structures to protect both the piling and the vessel from repeated contact. The 5-inch by 3.5-inch profile is purpose-built for vertical applications, with a higher-density 3-pound XLPE foam core sized to absorb the heavier loads that pilings see when boats rest against them in wind or current. The same modular three-part construction makes the fender field-serviceable for the life of the dock.
On most residential docks and many marina slip configurations, pilings are the first thing a vessel touches. The boat comes alongside, drifts toward the slip, and the piling catches it. On windy days or in current, that contact is constant: the boat rests against the piling for hours or days at a time, and every wave moves the hull against the piling surface. Without a fender, the result is predictable. Pilings splinter. Bow rails bend. Gelcoat abrades into the wood. Bottom paint scrapes off in stripes. The damage accumulates slowly until a major haul-out reveals it.
A piling fender solves this by putting a permanent, replaceable, impact-absorbing surface between the vessel and the piling. The fender is bolted directly to the piling and stays there. No ropes to manage, no fenders to lower over the side, no need to position the boat exactly right. The protection is always in place.
The Piling Fender uses the same three-part modular construction as the rest of the Slammer line, with one important difference: the foam core is 3-pound XLPE, denser than the 2-pound foam used in the Standard and Small horizontal fenders. The denser foam absorbs heavier loads without compressing through to the piling itself, which is the failure mode that matters most on a vertical application. The cover is the same 30-ounce PVC-coated marine fabric. The mounting track is a heavier polymer extrusion designed for the higher impact loads, with stainless steel deck screws or hex-head lag bolts depending on piling material.
The Piling Fender is sold in 40-inch, 80-inch, and 120-inch standard lengths. Custom lengths from 2 feet to 20 feet are available on request. The track installs on round pilings, square posts, and other vertical structures. Wood, composite, aluminum, and concrete pilings are all compatible.
The decision is geometric, not aesthetic. Use Piling Fenders anywhere the contact surface is a vertical post or piling. Use straight dock fenders anywhere the contact surface is a horizontal dock face. Many docks need both: straight fenders along the dock face, and piling fenders on the slip pilings at each corner of the slip. The two product lines are designed to coexist on the same dock and share the same modular component system, so foam core and PVC cover replacements are interchangeable between the lines (within the same size profile).
Hurricane prep and storm-season protection are common reasons boat owners install piling fenders. The fender does not eliminate the need for proper storm dock lines, but it does eliminate the most common minor-damage failure mode in moderate weather: the hull rubbing against the piling during the hours before and after a storm passes. For dock owners in hurricane zones, piling fenders pair with extra storm lines and chafe gear as part of a complete storm protection setup.
The piling fender is built to last, and when a component finally wears out, each part is sold individually. Replacement foam cores, mounting tracks, and covers are stocked at dock fender components. Most owners replace the PVC cover at the 5- to 7-year mark and the foam core at the 8- to 10-year mark. The mounting track typically does not need replacement at all.
