Emerson PolyOil jar handling clamp

The Emerson PolyOil jar handling clamp can be used for drilling, DST jars, coil tubing and wireline applications.

The clamp acts a safety device to prevent the jar from cocking and firing, with the jar unable to fire unless the fishing neck — designed to enable running and retrieval tools to reliably engage and release — is closed. Therefore, when the clamp is fitted to the jar, the rod is kept in the open position, preventing premature firing during the handling of the jar at the surface.

The clamp also prevents the jar rod from being damaged during transportation and keeps it debris-free during storage.

The clamp uses a range of high-impact, wear-resistant materials with the natural properties of the polymers making them low weight, safe, easier to handle than metal and more resilient. Other key features of the clamp include a hinged design with the clamp simple and fast to fit and a toggle/swing bolt for fast latching operations.
