The M81714/67-08 Mounting Tracks are fabricated of glass-filled polyetherimide which was selected for its unique combination of high strength, light weight, chemical resistance and dimensional stability. The track is available with 2 through 20 mounting positions, and is inter-changeable with existing aluminum tracks. This new track is 45% lighter than the aluminum track and 10% lighter than any other Series II track available. It also meets all dimensional requirements of MIL-T-817
