The Tank-Jak is designed to provide a portable means of lifting propane tanks for leveling, painting, resetting, etc. Sturdy construction and adjustable leveling chains allow it to be used on most 500 or 1,000 gallon tanks. The rounded foot allows the jack base to rotate slightly on the ground or support as the tank rotates upon raising. The two pads on the jack extension contact the tank surface to make the lift while the chains keep it in position.
