Clamping plates GN 953.6 are used in connection with position indicators GN 953 / GN 9053. In a simpler way and without large construction and installation effort these spindles can, after adjustment, be clamped and locked. At the same time these plates are fitted with the bore Ø 6,1 to accept the torque limiter for the position indicator. The spacer can be installed so that it lies as required either to the right or the left.
