Interchangeable jaw faces are available, and many grip models can be configured with smooth, serrated, or rubber-coated contact surfaces to better match your specimen material and surface finish.
Jaw-face selection typically depends on whether you are prioritizing maximum holding power or minimizing surface marking. Smooth faces are often chosen for more delicate or finished specimens, serrated faces are commonly used when slip resistance is critical, and rubber-coated faces can help increase friction on softer materials while reducing bite-in.
Availability and the best option can vary with the specific grip style, specimen geometry, and the load level you plan to run. Sharing your specimen thickness, material type, and target force range helps ensure the correct jaw insert size and surface type are paired to the right grip body.
