Everbilt Hang Track Insert

Homedepot sells these Everbilt Hangtrack shelves and Everbilt Hang Track rails which allow for a versatile arrangements. I needed just the base as I had an extra track and wanted to mount a large plywood to it. this insert goes inside the track, and allows a screw to be drilled from inside into plywood.  I used two of these blocks to hold the plywood. 

If you want a longer block, just extend it directly in the slicer.
