Dock Bumper Dimensions

The Zoro Select D26U is an extruded rubber dock bumper measuring 6 in overall height, 2.13 in overall width and 1.88 in overall depth. It is designed for marine dock protection and installs with a bolt-on mounting style. Two mounting holes with a 3 in on-centre spacing and 3/8 in diameter accept standard hardware. An 11/16 in access hole allows tool clearance during installation.

Suitable Applications And Limitations

This bumper suits dock owners who need a compact rubber fender for light to moderate impact protection. The 6 in height and narrow profile fit pilings or edges where larger profiles would interfere with boat access. Buyers needing a taller profile, wider face or different mounting pattern should consider other profiles. The fixed two-hole bolt pattern also limits use on surfaces that cannot accept drilled fasteners.

Critical Mounting Specification

The decisive specification is the 3 in on-centre mounting hole spacing with 3/8 in hole diameter. This fixed bolt pattern determines whether the bumper aligns with existing piling hardware or pre-drilled dock timbers. If the hole centres or diameter do not match the structure, the bumper cannot be secured without modification.

Questions about this item

How often will the extruded rubber bumper need replacement under normal marine use?

The bumper is made from extruded rubber sized 6 x 1.88 x 2.13 in; lifespan depends on impact frequency and UV exposure, so inspect regularly for cracking or compression set.

What is the first limit reached when the bumper absorbs repeated heavy impacts?

The two 3/8 in mounting holes on 3 in centres transfer load to the dock structure; bolt shear or hole elongation will occur before the rubber itself fails.

Does the rubber generate heat or noise when compressed continuously all day?

Rubber dissipates impact energy as minimal heat and produces no audible noise during compression; no power source is involved.
