Mount Kit

The 4 Gal Rain Basin requires two mount kits. This allows for an extra secure mount in locations like Tundra Bedrails, roof racks, and bed racks. The kit comes with keyed locks to secure your tank in place. To dismount the tank, twist the lock and slide the tank out of the mount -its that simple. See install videos on the video page.
