This Overhead Crown Guard is an accessory to fit the Axminster AT305PS, P30/2600 and pre April 2018 P305/2600 models. Recommended by the HSE as it offers much improved protection for the user as well as superior dust collection. It includes a riving knife suitable for blades up to 350mm diameter (P305 models only). Comes with two blade guards, a narrow one for vertical cutting, a wide one for angle cutting. Changing these is a simple, no-tool process. Hinges back for easy access to the blades. Simple to fit and a great enhancement.
