Lock-N-Lift Tools are not to be used for side pull or push. If the tools are dragged or pushed to the side or along the ground while in a steel trench plate, stress will develop on the ankle part of the tool causing foot breakage and/or the center plate to become pinched. If a tool is abused in this fashion, tool life will be shortened.
The Model 750 Tool is designed to be used with a shackle only and must be inserted into a Lock-N-Lift #500B weld plate. It may be used with a chain or anchor shackle.

How to use the Model 750 Lock N Lift clamp
Model #800 tools have been in use since 1988 throughout North America eliminating the need for pry bars, installation tools or thread cleaning when moving and storing road plates.
The Model #800 tool maximizes worker safety by eliminating the need to ever put a hand, foot or any tooling under a road plate, even during the installation of the weld-in plate.
The Model #800 has an elongated attachment hole, making it possible to lift road plates using either a hook or a chain shackle.
The Model #800 tool is made in the USA from the best available aircraft quality AISI 4340 steel. The tools are heat treated to provide a safe working load of 8,000 pounds with a 5:1 safety factor.
