Designed for 1/4-20 hex nuts, these nifty T-Tracks make jig
building easier, and allow me to make the jigs I build far more versatile.
In fact, its easy to
get carried away and build jigs that are much more versatile than they
really need to be. Most T-Tracks require the use of special threaded nuts
that slide in the track itself. These Incra T-Tracks accept standard 1/4-20 hex nuts (not included). The single
T-Track recesses in a 3/4" x 1/2" deep groove and is attached
from the top with supplied wood screws.
