for user-made fences, this aluminum extrusion combines a T-slot track
with a recess for an adhesive measuring tape (such as our bench tapes,
item #25U02.40). It attaches to the fence using either T-bolts – using
the T-slot track underneath the tape recess – or screws.
The T-slots accept any 1/4-20 T-nuts and T-bolts. Our flip stops (item #13K1208), designed for this track, extend over the measuring tape to allow direct reading.
