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.

 

The Mash Monster collection features custom Warren Tetting grippers made to replicate the original GripBoard certification grippers. The GripBoard Mash Monster certification is unique because every athlete at each level has closed the exact same gripper. These replicas offer you a chance to prepare for certification or test your strength against the athletes who are officially Mash Monster Certified!
