The Brace Tool GU Adapter is a specialized component used in wireline services, particularly designed for operations requiring downward jarring. It is typically used in conjunction with a GS Pulling Tool, where the GU Adapter sub is attached to the top of the GS Pulling Tool. This setup allows for efficient retrieval of downhole components by facilitating downward jarring. The GU Adapter features a shear pin mechanism, which must be removed from the shear down GS Pulling Tool and installed in the GU Adapter sub, enabling shearing through upward jarring.
