Re: Cable Gland - Waterproof RJ-45 / Ethernet connector - RJ
Looking at the photos on your product page, I see your cable does have a boot, and it looks roughly the same size as mine. The boot+connector on my cable is 34mm long, fwiw.
I'll try to cut the strain-relief off the boot, and if that fails, I'll just cut the connector off and crimp on a new one.
BTW, the note you added to the product page could use a correction. In the statement "the boot can get in the way of the cable", it should be "gasket" instead of "cable".
