Rubber Dock Bumper 4 x 3-3/4 x 12 In

The Buyers Products D412 is a solid rubber bumper designed to protect dock edges and boat hulls during mooring. Its rectangular profile measures four inches by three and three-quarter inches by twelve inches, providing a substantial contact surface for impact absorption. This new component is intended for marine environments where durable cushioning is required.

Suits Fixed Dock Edges Not Curved Surfaces

The flat rectangular shape suits straight dock edges, pilings or seawalls where a broad mounting face can be secured. Boats with highly curved gunwales or installations needing a cylindrical or D-profile fender will not achieve full contact with this bumper. Buyers seeking a lower-profile strip or a different mounting hole pattern should consider other profiles.

Length Twelve Inches Determines Coverage

The twelve-inch length is the single dimension that decides how much linear dock edge each bumper protects. Spacing between units depends on this fixed length and the expected vessel size. No other specification in the data alters the coverage calculation for a given installation.

Questions about this item

What does the 12-inch length mean when the bumper is mounted on a dock?

The 12-inch length gives a continuous rubber face along the dock edge to absorb impact across a wider area.

How does the rubber material attach to the dock structure?

The bumper is designed to be bolted or lag-screwed through pre-drilled holes in the rubber body to the dock framing.

What clearance is needed behind the bumper for the 3-3/4-inch projection?

The 3-3/4-inch projection requires at least that much clear space behind the dock face so the bumper can compress without hitting the structure.
