The most common stopper in Multi-Rail RM fixturing system is RMS-S, which has two smooth and nitrided jaws.
It is the optimal choice for the second setup to avoid marking even when OK-VISE clamps are used with full force.
Friction level is suitable even for roughing and other types of machining where high forces occur.
The accuracy from every serrration to the jaw surface is ± 0.01 mm.
