Assembly
[1] PG7 cable gland pre-assembly
Screw PG7-cable glands (PG7-thread) into the PG7 openings of the adapter.
Close unused PG7-opening with PG7-blind stuffing.
Use optional TPU PG7-sealing if necessary.
[2] PG21-adapter assembly
Place the pre-assembled PG21-adapter (blind stuffing) in the PG21 opening and secure it with a PG21 nut.
Optionally place PG21 sealing on the PG21-adapter before assembly.
[3] Cable assembly
Guide cable through PG7 cable gland and fix cable by fastening the corresponding cable gland nut.

Hint: 
Apply some silicone grease on the thread, so it can be easily be assembled and disassembled.
(Without grease, the thread tends to wind on and off somewhat “sticky”.)
