General Information

The following sections contain general information about the product.


If you need to grip in a weld environment, the sealed mechanism of this gripper will keep weld-contamination out.


BTM's Sealed Heavy Duty Grippers are designed to provide high gripping forces and long work life within a rugged & reliable unit.

There are four NAAMs compliant mounting locations on each side of the gripper body for your convenience, and the one piece body eliminates premature wear due to misalignment.

TriLok Equipped


BTM's patented TriLok mechanism is a three point lock which remains engaged even if air pressure is lost. In addition to locking, the mechanism also provides accurate arm position and repeatability.

The exclusive TriLok mechanism removes all working tolerances from all moving parts to provide a very repeatable (± 15') and rigid closed arm position. This unique arrangement is highly resistant to torque coming from force applied to the clamp arm.

  • Three Point Lock: Remains Locked if Air Pressure is Lost
  • Arm Repeats Position Accurately
