The Incra ShopStop is their most versatile stop. The vertical stop bar is adjustable up and down, it can be reversed, and it has a screw-based micro adjustment. The ShopStop is also expandable - the top section can be slid into a second channel on the base section to make the interior wide enough to span an Incra fence and a wooden sub fence up to 19.0mm thick.
INCRA's patented positioning mechanics make it deadly accurate and completely repeatable.
The ShopStop comes standard in the LS Joinery & Super Systems, however if you need a second, super-accurate stop to use on your Incra Jig or mitre gauge fences then its handy to buy one separately.
