Abstract: A work holder used for guiding a workpiece moved from one position to another during placement of the same and particularly sheet piling. The holder has an elongate rigid arm with an abutment at one end thereof for bearing against a rigid structure and a friction reducing unit at the other end of the arm for bearing against the workpiece during movement of the same. Between the abutment and the friction reducing unit there is a device for applying pressure to the arm to press the friction reducing unit against the workpiece. The pressure applying device has a first unit adapted to be detachably anchored to the rigid structure and a second unit, variable in length, connecting the first unit to the arm.
