Wall unit lifters make it much easier when lifting and moving concrete wall units in place. The prongs on the end of this hardscaping/landscaping tool are placed in the wall unit's end holes. Once lifted, the hinged handle bar locks onto the wall unit, providing the user with a much easier time moving heavy blocks. The prongs grip the holes and the block weight secures its hold. This is a durable product that was built to last. Bon Tool's products have been trusted by professionals for over 60-years. Bon is committed to the development and improvement of tools for professional contractors and do-it-yourselfers alike. We put our trusted name to every product we sell.
