Zero-Clearance inserts provide maximum support for easily chipped materials, such as veneered plywood and high-pressure laminates, by eliminating the gaping slot between the throat-plate edge and the blade. Simply raising the blade through a fresh insert forms a slot that exactly matches your saw’s kerf. For most saws, this exceptionally well designed, high density phenolic insert is a full 1/2" thick, and has a bonded melamine surface. Leveling screws make set-up quick and easy, while side and end take-up screws allow for a tight, vibration free fit. Check dimensions on each plate to verify your correct size. Note that the thickness measurement refers to the thickness at the mounting edge of the plate, not the overall plate thickness. Color may vary.
