Rectangular black rubber dock bumper with four bolt holes

Value Brand

Value Brand Dock Bumper 6x4-1/2x32-3/4 in. Rubber

SKU CH-9AA8-M6TXQ

Laminated rubber dock bumper with four bolt-on mounting holes on 36-inch centres

  • Absorbs heavy impact with laminated rubber construction
  • Rectangular profile covers 32 1/2 in width for broad hull protection
  • Four bolt-on holes at 36 in spacing simplify installation
  • 6 in thickness cushions dock and vessel during docking
  • Meets California Proposition 65 chemical disclosure requirements

Dock Bumper Dimensions

The Zoro Select laminated rubber dock bumper measures 6 inches high by 4-1/2 inches deep and 37-3/4 inches wide overall. It is built for marine docks that need a rectangular impact surface between pilings and approaching vessels.

Replacing Worn Laminated Bumpers

This bumper replaces an existing 32-1/2 inch wide laminated rubber unit with the same 6 inch height and 4-1/2 inch depth. The upgrade is worth it when the old rubber has cracked, compressed permanently or lost its mounting hardware.

Bolt-On Installation Notes

Four mounting holes of 13/16 inch diameter are spaced 36 inches on centre horizontally and 3 inches on centre vertically. Alignment across the full 37-3/4 inch width is the common difficulty; verify hole spacing before drilling.

Questions about this item

What are the mounting hole diameter and spacing for the 32-1/2 in. wide bumper?

The bumper has four bolt-on holes, each 13/16 in. diameter, spaced 36 in. centre-to-centre horizontally and 3 in. vertically.

How do I bolt the bumper to the dock without misaligning the 36 in. hole centres?

Drill four 13/16 in. holes at 36 in. horizontal and 3 in. vertical centres, then fasten with bolts; the common mistake is measuring from the bumper edge instead of the hole centres.

When should I replace the laminated rubber bumper?

Replace it when the rubber shows deep cracks, permanent compression, or the 13/16 in. mounting holes elongate from bolt wear.
