Questions about this item

How do I bolt the 20 in dock bumper to the dock face and what spacing mistake should I avoid?

Drill six holes matching the 13/16 in diameter, spaced 11 in on-centre horizontally and 8 in vertically; the common error is measuring from the bumper edge instead of the hole centres.

What part of this rubber bumper will wear first and need replacement?

The 4-1/2 in thick rubber face absorbs every impact and will eventually crack or compress, requiring the whole bumper to be swapped out.

Which limit appears first when boats hit this bumper repeatedly in hot sun?

The rubber softens under sustained heat and heavy strikes, losing rebound and allowing hull contact with the dock structure.
