Improve your router table's dust collection! This computer-machined MDF adapter allows attaching the INCRA CleanSweep Dust Collection Cabinet to router tables with corner-mounted plate levelers and 9-1/4" x 11-3/4" plate openings such as Kreg, Woodhaven, and laminated MDF tables from JessEm. In addition to providing normal access to these tables' original corner-mounted lever leveling system, the adapter replicates the router plate support ledge found in the openings of INCRA router tables, complete with 10 large-diameter leveling bolts. Because it increases the plate's support surface, the CleanSweep Adapter is perfect if you own a Kreg or other "ledge-less" router table and want to upgrade to compatibility with an INCRA MagnaLOCK router mounting plate or INCRA router lift. Includes 10 lo-head router plate leveling bolts, screws for attaching the adapter to the router table, and longer screws for mounting the INCRA CleanSweep Dust Collection Cabinet. The outside dimensions are 15 1/2" x 15 1/2"
