Model #05G12.01. You can clamp anything anywhere in the vise and the jaws stay parallel. The chain drive ensures parallelism and eliminates the racking common in other vises. It can be operated using either handle. In opened box but complete with all parts, everything in new condition, never used. Model on offer is an earlier version, although almost identical to the one shown on the website link. One difference is the chain cover design and material (plastic) in Model #05G12.01. This version also allows for adjustable spindle separation (11" - 20") rather than fixed. Please note the seller is in Metchosin. If ad is still posted, item available.
