You’ll wonder how you got along without one. Or two. The Nautical Cross slips into your flush-mount rod holder, locks in, and lets you tie off fenders and buoys. Properly protect your boat from damage. Or tender jet skis, bags, pitch baits, etc. The 1 ½” Nautical Cross locks securely into your flush mount rod holder of the same diameter. Made from finely polished, non-rusting aircraft grade aluminum with a plastic liner. If your vessel doesn’t have flush-mount holders, Nautical Cross makes one that’s ready to install.
