M85049/21-11W02A decodes as slash sheet /21 (straight, spin coupling) + shell size 11 + finish W (olive drab cadmium over electroless nickel) + cable entry size 02 + the A dimensional suffix. The spin-coupling nut rotates independently of the backshell body, so tightening the backshell onto the connector does not rotate the cable bundle or twist the shield braid. That is the difference between the /21 and the direct-coupling /29.
The M85049 accessory range is common across connector manufacturers; any QPL backshell with the same slash sheet, shell size and finish intermates with the equivalent D38999 connector from any source.

The /21 is specified for 38999 Series III and IV, where the connector coupling is a triple-start thread rather than a bayonet. Spin coupling matters most on high-contact-count inserts, because the alternative is rotating a heavy, fully-populated cable bundle. Airoadcon supplies the M85049 accessory range in straight, 90° and 45° configurations across the full shell-size matrix.
