The Expandable Grab is generally run after the wirefinder. The spring loaded prongs of the Grab continually run against the tubing wall ensuring theat the wireline will entangle inside the prongs of the Grab.
The advantage of the Expandable Grab over the more convenient tool is that it will not pass through the centre of the wire coils if the line has not been balled correctly. It will also pass through restricted internal diameter of the nipples etc. expanding into the larger internal diameter further downhole.
The Expandable Grab is manufactured with a central box thread so a Centre Spear can be attached if required.
The tools can be manufactured to suit any size required.
