Vertical retrofit vise for secure clamping of agate nodules that fits the Highland Park HT10, HT12 and HT14 slabs and the Lortone LS10, LS12 and LS14 Panther glass coldworking and lapidary equipment slab saws. Replaces the horizontal clamping bar. 

NOTE: Some of the older Lortone saws had different vise bolt hole pattern and new holes would need to be drilled to accomodate this vise on those saws.
