A gripper clamp is provided for facilitating the handling of screeds used in the rough levelling of concrete. The screeds are usually two by fours or two by sixes and are held by workmen at opposite ends. The handling of such screeds is simplified by the use of a gripping tool including a first handle having right angularly extending jaws to engage one side of the screed and a relatively movable handle pivotal relative to the first and having a jaw end engageable with the side of the screed engaged by the first-named jaws.
