The revolutionary SawStop protection starts here! This is the SawStop brake cartridge for 8" dado blades. It fits all models of SawStop table saws (except for older models). Current SawStop models use cartridges with blue tinted plastic cases and 9-pin connectors. If you have an older model with a clear case and a 15-pin connector, you will need a different cartridge; please call SawStop for details.
