Machine guarding doors protect people and processes in highly-automated production areas. The Albany RP300 is a machine guarding door with narrow, aluminum side frames, various flexible curtain designs and colours. The extra-tough plastic guide elements hold the curtain firmly in the guide rails, even if pressure is exerted by a person or equipment. The Albany RP300 syncs with short cycle times, and can be installed in machines, production lines, and railing systems which are close to the machine.
