Add this service to your cart, then update the quantity to match the number of grippers to be filed and rated.
Why is filing beneficial?

Please note that the Filing Service permanently alters the gripper. Grippers are always filed first, then rated. Our custom filing process leaves a beautiful finish on the cut surface of the gripper handle.
If not all the grippers on your order will be filed/rated then you can specify which gripper to file/rate in the notes at checkout. You can also specify which color tag goes with each gripper if multiple colors were ordered. Email email@example.com if you have questions.
Grippers in a sealed package (IronMind, GHP) must be opened for the rating and filing service. You will still receive the packaging with your gripper.
