Matchfit Dovetail Groove Hardware (MicroJig)

I shrunk the height down to 6mm so the hardware is able to do its job and snug up against the groove. At the size it was it was too big to be able to snug up to the dovetail groove, but it was useful as a slider.
It uses 5mm bolts or nuts.

There are 3 different lengths: 40mm, 50mm and 100mm

I definitely recommend buying the original MicroJig Matchfit 1/2" router bit, it leaves a nice smooth finish at the top of the dovetail groove and after using them quite extensively I feel that the 1/4" bit would leave me nervous (if you only have 1/4 collet I would suggest going slower than you usually would)

NOTE: After trying out the large 100mm 2 bolt version in a stop block, I find it useless. It doesn't grab as well as using 2 separate shorter pieces. I will leave the file in case it suits your needs but just wanted to give my impressions.
