Leecraft DW-3 Zero-Clearance Dado Table Saw Insert for Dewalt Saws -Colors May Vary-

Leecraft model DW-3 fits DeWalt: DW744 & DW745 (factory splitter/guard incompatible with DW-3 insert on these saws); DW746 & DeWalt DWE7480, DWE7490X, DWE7491RS, DWE7499GD. LEECRAFT Phenolic Inserts and Sheet Stock reduce splintering and chip-out on the bottom side of regular or dado table saw cuts. Simply raise your saw blade through the insert to create a "kerf" which precisely matches the blade on your saw. Complete with instructions. Insert surface colors may vary.  Insert is the same design as Leecraft's DW-2 with the only change being more material is removed from the bottom.
