Clamping Kits

Northwestern's Clamping Kits reduce the set-up time needed on milling machines, boring mills and for other machine table operations. All the studs, nuts, clamps and blocks are kept organized, and within easy reach.

When using step blocks with clamps, be certain clamp teeth are fully engaged with teeth on step block to prevent damage to block or clamp.

For your higher clamping requirements, click here to use our Hi-Rise clamping system.
