Hey Gang, This question goes out to all the diehard security installers and integrators: DOES ANYONE KNOW WHERE I CAN FIND WATER TIGHT GLANDS SIMILAR TO WHAT YOU'D FIND INCLUDED WITH A PELCO EH3512 OR EVERFOCUS EHD650? I recently mounted two (2) Nuvico CI-Z30N Integrated Zoom cameras on two trees and have yet to seal the entrance (top) and exit (bottom) holes of each 3/4'' metal junction box. I have searched Home Depot, Lowes, and even the internet trying to track down a 3/4'' THREAD COMPRESSION GLAND to weatherproof these openings. Clear silicone works great but I just know such gaskets exist and are availble for purchase. It doesn't matter to me if they are metal or plastic, but I do need it to tighten up like...well, you know what I mean. Just to summarize, I'm searching for a 3/4'' thread-->tapered compression gland/sphincter:) Thanks in advance. Ps-These cameras of the shizzznit. Dan
