Questions about this item

Does the bumper arrive with the bolts and washers needed for the 1 1/4 in mounting holes, or must I supply them?

The unit is a rubber bumper drilled for three 1 1/4 in bolt-on holes on a 10 in centre pattern; fasteners are not included and must be purchased separately.

The 18 in by 18 in face and 4 in depth are the only size offered — how do I know it will cover the contact zone on my dock?

The bumper presents an 18 in high by 18 in wide impact face with a 4 in projection, matching the listed overall dimensions; measure your piling or wall contact area against those figures to confirm coverage.

Once bolted to a concrete dock wall, how much energy can the 4 in thick rubber absorb before the hull feels the load?

The 4 in rubber depth compresses under impact, spreading the load across the 18 in by 18 in face and the three-bolt mounting pattern to reduce peak force transmitted to the structure.
