Designed specifically for the SawStop CNS Contractor Saw, this mobile base allows the saw to be easily moved around the shop. The fully-welded 1/4" rigid steel construction and black powder coat finish will stand the test of time and take the abuse that is often associated with mobile bases. This unit is so rugged that it supports the entire table and requires no extension piece - even for the 52" extension table. The casters are made of durable polyurethane and feature two fixed-direction wheels and two casters that swivel 360 degrees for easy positioning. Designed for easy one foot operation.
