Multi-Stage wireline pressure setting tools differ from single stage compact tools in that an extra top piston and companion
cylinder are added to the tool which then doubles the pulling strength ability of the tool. In addition, the tool has a longer
stroke length. The multi stage tool is used primarily to set Magna Range Bridge Plugs which require extra stroke length, Another

stroke to set the bridge plugs and casing patches.
The tools feature pressure balanced top and bottom pistons and eliminate presetting of the mentioned products caused by high
