MK3 ULTRA Rail Square® Wall Mount

As far as I am aware there is not another decent quality track square available for Bosch track saws. Not only does this fill that gap, but the design that supports pretty much every track saw on the market in ONE square is amazing. Quality is top notch. Machined to precision. Incredibly accurate. Packed like a quality tool complete with a calibration report for each individual square. Shipping to the states was surprisingly fast. As a hobbyist with mid range tools, I put this right there with my few Lee Neilsen hand tools in terms of quality, but even better in affordability. I intend to be a Benchdog customer for life.

Works great with just the Mk3 Ultra however, when attached with the Ultra Max extension, it only attaches with the middle hook allowing it to swing when knocked. Bad design decision here, unless i’m missing something; removing the extension shouldn’t be an option.
