The Ruwi clamping and sawing system is an effective occupational safety device which can be mounted and adjusted on standard sliding table saws without tools in no time at all. It offers a high degree of safety when cutting inclined, short, narrow and wedge-shaped workpieces of different sizes. The clamping arm length and the slot nut on the swivel clamp are designed for format 4 machines. Various auxiliary stops can be placed or fixed quickly, safely and easily to suit the workpieces. An arrangement panel for wall mounting ensures that the individual components of the work safety device are always in place and quickly accessible. The standard version Set 1 consists of a feed fence with handle and an "auxiliary fence angled". Both can be pushed without tools and are variably clampable and adjustable. In addition, this set also includes a swivel clamp. This is a height-adjustable, 360° swivelling quick clamping system for workpiece clamping.
