DEWALT DW7440RS Rolling Table Saw Stand has a lightweight design, weighing only 33 lbs
I’m sure. Mine is older Craftsman. Had to add 3/4” plywood base. No big deal.
I have my 10" Makita Contractor's TS secured with 1/4" x 1-1/2" bolts. The actual slots on the DW mounting brackets are 5/16" wide and run almost the entire length.
