The only self leveler in the industry, this exclusive balancing mechanism is housed inside the hook body. The operator simply slides the hook fully into the pipe, then lifts and moves it to the destination. The weight of the pipe automatically levels itself. Self-leveling models are available up to 9000 pound capacities. The self-leveling mechanism is housed inside the body of the hook. Like the manual slide models, the self leveling pipe hooks can be used on ANY shape or type of pipe.
