Dock bumper for marine protection

This rectangular rubber bumper measures 12 inches high by 19 3/4 inches wide with a 4 1/2 inch depth. It mounts to dock surfaces using four bolt holes spaced 18 inches across and 8 inches vertically. The hardware suits commercial or residential waterfront installations.

Bolt-on mounting with four holes

The 13/16 inch diameter mounting holes accept standard bolts for a secure attachment. Pre-drilled centres at 18 by 8 inches simplify alignment during installation. No adhesive or specialised brackets are required, reducing fitting time on site.

Solid rubber construction withstands impact

The one-piece rubber body resists UV exposure, salt water and repeated vessel contact without cracking. A 14 1/2 inch bumper face absorbs kinetic energy from docking manoeuvres. The material stays flexible in cold temperatures and does not rot like timber alternatives.

Questions about this item

How often will the rubber bumper need replacing under normal marine exposure?

The rubber construction resists weathering; replacement timing depends on impact frequency and UV exposure rather than a fixed interval.

What dimensional limit is reached first when the bumper compresses against a docked vessel?

The bumper depth of 4-1/2 inches determines maximum compression before the mounting plate contacts the hull.

Does the bumper radiate noticeable heat or require power during all-day use?

No — it is a passive rubber buffer with no electrical components, so it generates no heat and draws no power.
