Material: The bars are made from premium anodized aluminum and are designed to prevent damage from the saw blade and router bit during the setup process. Exclusive 3-Gauge Design: Each bar essentially gives you 3-in-1 (step, depth, and fence) for project versatility and offers steps on the top, bottom, and ends. Concave step on the bottom for precisely setting height. The top step serves as a gauge for testing the depth of completed cuts. The end step sets the distance from the table saw blade or router bit to the fence. Applications: Perfect for router tables, table saws, and even shapers. Includes: 7 router table setup bars, 1/8", 3/16", 1/4", 5/16", 3/8", 7/16", and 1/2". Quantity: 7 pieces. Color: Blue.
