Feichao's Knurled Aluminium Nut Adapters: Lightweight adapters of the sandblasted kind

The Feichao Knurled Adapters are lightweight versions of a standard camera accessory - the thread adapter / converter.  GPN Media use the Female 3/8" to Female 1/4" knurled adapter as a cold shoe locking nut for their Leg #4 component (part of their Scrambler UL Modular Tripod) and the 1/4" Male to 1/4" Female as an extender.

Obviously there are myriad and far more orthodox uses for these adapters.
