Jegs 79009 Bottle Jack 20-Ton Capacity Air Assist

Lift Height: 10-7/16 inch to 20 inch - Lift Height with Extension Screw: 23-1/8 inch Weight: 33 lb - Width: 9 inch - Length: 5 inch - Air Line: 1/4 inch NPT x 52 inch L JEGS 20-Ton Air/Hydraulic Bottle Jack is designed to operate manually or pneumatically. Use with a 100120 PSI rated air pressure supply to get fast, strong lifting power; or operate it manually just about anywhere, even without an air supply. A safety overload valve offers extra protection if you load the jack up with too much weight. The safety overload will gently lower the unit before the operator is put in a dangerous situation. The 10-7/16 to 20 lift range raises the load and the 3-1/8 extension screw allows you to fine-tune the jack from there.
