Cylinder Grabbers

Safely move gas cylinders and other heavy, hard-to-grasp objects. These grabbers have a scissor-like design that firmly grips the sides of a cylinder when you pull up on the handles. You can lift them on your own or share the load with another person. Padding on the handles makes them comfortable and easy to hold.
