High Country SL-39 Plastics Slant Load Upright Water Caddy, 39 Gallons. Allows you to take 39 gallons of fresh water with you on your next road trip and fits conveniently in the corner of your walk-in tack room utilizing the "dead space" in the corner. The SL-18 is a perfect alternative for those trailers that require a smaller "footprint" than the SL-25 or SL-39. We manufacture it with FDA approved polyethylene so the water is safe for you and your animals to drink. Translucent poly allows you to easily check water levels in the tank. Fill cap is located on the very top middle of the water tank. Two molded in aluminum 3/4" drain inserts ensure the drain attachment spot will never break, sun rot or fail. Two 3/4" shut off valves included. The top shut off valve allows for filling a bucket without needing to attach a hose. The bottom shut off valve allows for draining all of the water from this tank. The strap kit provided makes installation quick and easy.
