Learn how to install and use the WaterPORT Bar Mount to securely attach your 4-gallon tank to ATVs, boats, and vehicle rails.
Quick answer
The WaterPORT Bar Mount lets you fasten a 4-gallon Day Tank to any bar or rail up to 1.5 inches in diameter. It works on ATVs, boats, truck racks, and other tubular surfaces where you need a secure, portable water system.
Why choose the Bar Mount over other mounting options
The Bar Mount is purpose-built for round or square rails, which makes it ideal for vehicles and watercraft where flat surfaces are scarce. Unlike a standard strap or bracket, it wraps around the bar and cinches tight without drilling or permanent modification.
One trade-off: the mount is only compatible with the 4-gallon WaterPORT Day Tank. If you own a 2-gallon or 8-gallon tank, you will need a different mounting solution. Also, the bar diameter must not exceed 1.5 inches, so measure your rail before purchasing.
Step-by-step installation guide
- 1. Position the mount on your bar: Open the Bar Mount and place it around the rail or bar where you want the tank to sit. Ensure the mounting plate faces outward so the tank can attach later. Common mistake: placing the mount upside down. The tank will not hang level if the plate is reversed.
- 2. Tighten the strap evenly: Pull the strap through the buckle and cinch it hand-tight. The mount should not slide along the bar when you push it. Avoid overtightening, which can damage the strap or the rail coating. Checkpoint: after cinching, try to rotate the mount. If it moves, tighten slightly more. If the rail has a textured surface, the mount will grip better.
- 3. Attach the WaterPORT 4-Gallon Day Tank: Slide the tank onto the mounting plate until it clicks or locks into place (refer to your tank’s manual for the exact locking mechanism). Give the tank a gentle tug to confirm it is secure. Common mistake: forcing the tank onto the plate when it is misaligned. Back off, check alignment, and try again to avoid breaking the locking tabs.
- 4. Test the setup before filling: With the tank empty, shake the assembly firmly. If the mount or tank wobbles, reposition or tighten. Once satisfied, fill the tank and check for any sagging or movement. Checkpoint: a full tank adds significant weight. If the mount shifts when loaded, the bar diameter may be too small or the strap may need a tighter cinch.
