Slammer Marine Supply Store: Dock Fenders and Components

USA-made integrated dock fender systems and the parts that keep them performing season after season.
USA-Made . Patent Issued . Fender-to-Fender Warranty . Trusted in Marinas

Slammer Marine is a USA-based marine supply store and manufacturer of permanently mounted dock fender systems. Unlike hanging fenders that shift, deflate, and end up in the wrong spot, every Slammer system attaches to the dock and stays in place. The shop is built around two product lines. Complete dock fenders cover the dock face, corners, and pilings, while replacement components keep an installed system performing for years. Marina operators and residential dock owners can shop the full range below, starting with the fender that matches the dock.

Dock Fenders

Slammer dock fenders mount directly to the dock and protect the hull at every contact point. Three profiles cover the most common dock configurations, from straight runs to 90-degree corners to vertical pilings. Each profile uses the same modular track, so a single dock can combine more than one.

Straight Dock Fenders

Horizontal protection for the dock face and straight runs.

Corner Dock Fenders

Coverage for 90-degree dock intersections, the most impact-prone point on any dock.

Piling Fenders

Vertical protection for pilings and mooring posts.

Dock Fender Components

Every Slammer system is modular, so individual parts can be replaced without removing the whole fender. Genuine components are built to fit Slammer tracks exactly, which keeps the fit precise and the warranty intact. Replacing a single core or cover costs far less than a full unit and extends the life of a system already on the dock.

Foam Cores

Replaceable closed-cell XLPE foam inserts in standard and piling densities.

Tracks

Pre-drilled polymer mounting tracks and hardware.

Covers

PVC and Polartec fleece outer covers in four colors.

How the Integrated System Works

Three-step graphic, horizontal on desktop and stacked on mobile:
  1. Mount the track. Pre-drilled polymer tracks fasten to wood, aluminum, or concrete docks with basic tools.
  2. Slide in the fender. Closed-cell foam fenders lock into the track and stay put. No ropes, no air.
  3. Finish and protect. Covers add UV resistance and, in fleece, a soft surface for fiberglass hulls.

Caption line: The same track accepts straight, corner, and piling fenders, so a single modular system can fully fender a dock.

Frequently Asked Questions

What is the difference between dock fenders and components?
Dock fenders are complete units that mount to the dock and protect the hull. Components are the replaceable parts of those units, including foam cores, tracks, and covers.
The choice depends on dock shape. Straight runs use straight fenders, 90-degree corners use corner fenders, and pilings use piling fenders. Most docks combine more than one profile.
The system installs on wood, aluminum, and concrete docks, and on both fixed and floating docks.
Can components be replaced without buying a whole new fender?
Yes. The modular design lets a foam core, track, or cover be replaced on its own. Genuine Slammer parts are built to fit Slammer tracks.
Yes. Slammer Marine manufactures its fenders in the USA using closed-cell foam and a PVC-coated outer fabric.
Slammer Marine offers a fender-to-fender warranty with no-hassle repair or replacement. Terms differ for private and commercial use.
