Buyers Products Water Cooler Mount is designed to mount to any flat surface trailer and holds most standard 3 to 5 gal water coolers (not included). The mount has an adjustable nylon strap to tighten your cooler so it stays sturdy. When it’s time for a refill, just unhook the straps and remove cooler to fill. The rack is constructed from sturdy steel and finished with a rust-inhibiting white powder coat to protect against wear and tear. Racks are made in the USA and include all mounting equipment.
