Speedy Grip Thumbscrew & Additional Jig Block (Extras bundle)

An additional black jig block and an easy-grip fast-tightening thumb screw that is too large for us to put in our regular packaging (otherwise we would). This is an EXTRAS bundle: your original SmartSquare package comes with all the necessary parts to use it. The thumb screw in this bundle tightens fast and is a quality-of-life improvement.
