This specially-designed suite of safety tools received the National Safety Council's Achievement in Product Safety Award when it was introduced to the market. These tools have changed very little since their introduction in 1984 which is a testament to the quality and thoughtfulness put into creating them. Each piece is designed to give positive, secure hold over your workpiece while also providing an additional layer of protection between you and the cutting surface. The Shopsmith 5-Piece Safety Kit Includes: (1) Push Stick, (1) Feather Board, (1) Fence Straddler for Ripping, and (2) Rubber-Soled Push Blocks. (This item is only for MARK 7 and other MARK models with the Pro Fence System)
