A patented "goof-proof" tool which applies materials at a precise, uniform depth. Apply decorative concrete “toppings,” self leveling / high performance floor coating materials, and underlayments. CAM® depth settings range from 1/32” to 1-1/2”. Includes an aluminum frame with either a threaded handle adapter or a powder-coated aluminum handle. Choose your frame size and handle option and then choose your CAM® set. Frames and sets are sold separately. When one contact point wears down, you simply loosen the wing nut and rotate the CAM® to a fresh contact point. We use a “radial” edge design which maintains uniform coating thickness, even at varying handle angles and lengths.
