Warren Tetting


Effective February 15th, 2015 Warren Tetting has announced his retirement which means THOR Strength Equipment will be shutting its doors and all Tetting grippers will be discontinued.  Warren's contribution to the gripper community cannot be summed up easily, but the word "legendary" comes to mind.  We are forever grateful to Warren and the legacy he has built.  This announcement rather caught us by surprise and our small remaining inventory has been updated.  Prices reflect the sudden collector status the few remaining grippers hold.  


Warren Tetting is the grandfather of torsion spring grippers. Every workhorse in the Tetting line is assembled by hand and features aggressive knurling and pinned handles. Tetting also makes the Mash Monster replicas, a Cannon PowerWorks exclusive! These are custom grippers made to match the specifications of the original Mash Monster certification grippers.

Made in the USA.
