Zoro Select Dock Bumper 22NT81

This rectangular rubber bumper protects dock edges and boat hulls during mooring. It measures eight inches high by five and a half inches wide with a three and a half inch depth. Four bolt holes allow secure attachment to timber or metal structures. The unit is new and ships directly from Zoro.

Check mounting pattern before ordering

Verify that your dock framing matches the hole centres of five and a half inches horizontally and three and one eighth inches vertically. Each hole diameter is nineteen thirty seconds of an inch so bolts or lag screws must fit that clearance. An access hole of one and a half inches provides room for tools during installation. Ensure the mounting surface is flat and solid enough to hold the hardware.

Suits small craft and fixed piers

Boat owners needing basic impact protection for low profile vessels will find this bumper adequate. It is not intended for heavy commercial traffic or large yachts that require taller or wider fender profiles. Buyers who want integrated lighting or curved profiles should look at other styles. The rubber compound carries a California Proposition sixty five warning for cancer and reproductive harm.

Questions about this item

Does the bumper ship with bolts or do I need to buy mounting hardware separately?

The bumper is supplied as a single rubber unit with four pre-drilled 19/32 in mounting holes; bolts, washers and nuts are not included and must be sourced to match your dock structure.

How do I decide between the different Zoro Select dock bumpers listed?

This model measures 8 in high by 5-1/2 in wide by 3-1/2 in deep with a 1-1/2 in access hole and a 5-1/2 in by 3-1/8 in bolt pattern; choose it when those exact dimensions match your mounting surface.

What does the 8 in overall height mean once the bumper is bolted to my dock?

The 8 in height is the vertical face that contacts a vessel, so the bumper will extend that far from the mounting plane to absorb impact along its full rectangular profile.
