This mount combines the versatility of our popular “LeveLock” all-angle quick release, cam-action mount for instantaneous leveling, with our sturdy vertical, out-over-the-water Round Rail Mount. This mount is made entirely of 18-9 stainless steel and 356 anodized aluminum to outlast even the most severe marine environments. Quickly disassembles for stowage without tools, leaving no hardware on the rail.
