Rasto is a universal drill jig to complement Invis Mx and is particularly suitable for handrails. Constantly changing shapes make gauge construction a complex and elaborate process. Rasto represents the ideal solution to this problem, with no measuring or marking. Thanks to three positioning pins that can be inserted into 180 holes, the drill jig can be mounted securely on virtually any surface. The drilled holes always align perfectly because the pin positions remain unchanged when drilling the second work piece.
