M85049 backshells are the qualified accessory family for US military circular connectors — they terminate the cable shield, provide strain relief and set the cable exit angle. The /14-1 slash sheet is the self-locking straight version: a rotating coupling nut with a ratchet that resists loosening under vibration, plus a saddle clamp for the cable jacket. It is specified wherever a D38999 Series III/IV connector is used in a high-vibration zone and the harness must not back off — aerospace structural runs, engine-adjacent looms, rail and off-highway vehicle harnesses.
