The Riser allows you 1-3/4" additional height adjustment.

The PEAK Riser will work with our Pedestal Base or C-Clamp (It is compatible with bases or clamps that hold a 3/8" diameter vise shaft) and will accept vises having a 3/8" diameter riser shaft.  If you use a pedestal base, leaving the riser attached to your vise and disassembling it from the base will leave you with a flat base for easier transportation.
