Featuring a 65% higher working load than its predecessor, this black-finished 20' T6 plus+ Aluminum Rail from ARRI will more securely hold suspended lighting fixtures and curtains for photo and video applications. Advanced rail systems can easily be made by connecting two or more rails though end stops at each rail end. The spacing of rail brackets depends on the maximum load on the rail but should not exceed 78". The distance from a rail bracket to the end rail should not exceed 20". Brackets are required at any rail junctions and in the apex of curved rails.
