Slammer™ takes the fenders out of the boat and builds them into the dock! The Slammer integrated dock fender delivers full-time protection to both boat and dock. The problem with existing boat fenders is that they are not always in position to work, rendering them ineffective. The Slammer fender is always in the right position. Constructed from highly resilient marine grade materials, Slammer fender sections easily slide into a hidden track that installs in minutes and lasts virtually forever. No ropes, no deflation, no maintenance and multi-year proven performance in major marinas. Slammer is a no brainer!
