Features:The Basket Grapple with Long Catch Stop has an internal shoulder located at the upper end, to stop the fish in the best catch position. It is designed to stop and catch collars and tool joints, with sufficient length left below the Grapple to allow the joint to be packed-off with a Basket Control Packer. The Basket Grapple with Short Catch Stop (not shown) has a double set of wickers of two different internal diameters. It is used to stop and catch a coupling with a ruptured piece of pipe engaged in its upper end. The upper set of wickers will catch the ruptured pipe and act as a stop against the coupling, while the lower set of wickers will catch the coupling.
