INCRA I-Box Zero Clearance Backing Boards
One of the I-Box's many great features is that it has 100% zero clearance where the cutter exits your lumber for super-crisp joinery on both faces.
These replacement backing boards will save you the time you'd otherwise spend making replacements on your own...and save you from tracking down sometimes hard-to-find 1/4" MDF.
Use the option selector to order backing boards individually or in value packs of (3).
