Brownfield’s GS Type Pulling /Running Tool is designed to locate in standard internal fishing necks.

To engage the GS Type Pulling /Running Tool, a sit down weight is required for automatic engagement. To release the tool, downward jarring activates the release mechanism by shearing a pin. If required the GS Type Pulling /Running Tool can be converted to a Jar-Up Release (GR) by fitting a GU adapter.

For surface operations the dog assembly has a finger grip to enable the tools to be manually released from the fish neck whilst in the pinned position.
