The RMZ Tool Trap is designed to stop wireline tools from falling back down the well should the wireline accidently break at the Rope Socket when pulling back into the Lubricator. Hydraulic actuation is required to open the flappers prior to running downhole. Once the toolstring has passed; the sleeve is returned hydraulically to its first position, allowing the flappers to close. When returning to the lubricator, the flappers automatically hinge open to receive the toolstring from falling down hole.

Tool traps are manufactured with quick unions for easy installation within the Lubricator Package.
