The high-quality MatJack High Pressure Air Bag from B/A Products Co. is designed to provide you with enough leverage to lift up heavy-duty objects. It doesn_x0092_t require the need for a hand-cranked jack or other type of manual lifting equipment. The bag can minimize the effort it takes to put about an inch of space between the object and the ground. This incredibly durable bag is made from a tough material that can endure a number of tough surfaces. It is able to handle a working load limit of 13T in the 15_x0094_ x 15_x0094_ size, 22T in the 20_x0094_ x 20_x0094_ size, and 32T in the 21_x0094_ x 25_x0094_ size. First you slide the air bag right under the heavy-duty object, such as a wrecked vehicle or debris, and pump air into the bag so that it effectively inflates and lifts the load right up off of the ground, giving you plenty of room to work with.
