Abstract
The tool includes a tool head having a tapered portion at one end for receipt within the flexible snap ring of a filter bag for expanding the snap ring into seating and sealing engagement about the margins of the opening in the tube sheet to secure the filter bag in depending relation from the tube sheet. The tool also includes a slidable member or weight along its handle whereby, in the event the tool becomes stuck in the opening, the weight can be displaced upwardly to impact against a tool surface and thus jar the tool loose from its engagement with the snap ring.
