Summary

While this will mount to any 20x20 extrusion, I designed it specifically to accommodate these LED bars:

LED Under Cabinet Bars

The package comes with three bars but I'll only use two on my Taz 6, one front and one rear. The set of bars comes with little metal brackets that the bar snaps into but you don't need those with mount. The mount slips perfectly and snugly onto the end of the bars.

I mounted mine to the extrusion with M5 bolts and t-slot nuts, but M4 would be plenty.
