When replacing your pontoon decking or re-carpeting your existing deck, it’s the perfect time to inspect your deck bolts while everything’s disassembled. Upgrading your pontoon boat’s decking or carpet not only safeguards your investment but also ensures it stays stylish and safe, season after season. For a secure fit, pre-drill 1/4" holes through the new decking and aluminum cross channels, spacing them 12" to 16" apart. Insert these 3" zinc-plated deck bolts through the holes, then tighten them from beneath the boat using the included flange nuts.
