<div dir="ltr">I have a wiring question, not so much about the cabling itself but about conduits.. I need to run a cable across the ceiling of a room in the basement. There's no good way to put it in the ceiling without having to tear down drywall and drywall is way above my pay grade.. Regular conduit would look ugly in this case. So my wife had the idea of running a "steampunk" conduit, one that's actually made of copper pipe (with appropriate fittings, bends, etc.). What I need to know is if there's any chance a copper pipe might interfere with the signal or cause EMI or anything? <div><br></div><div>Does anyone know?</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Tue, 30 Jan 2018 at 11:09 R.

You may still need to remove and replace the end of a cable if you want to feed it through a small hole. I know the tolerances of devices are pretty good, but I would be hesitant about patching together 3 or 4 segments with RJ45 connectors when a single line can be run end-to-end with just a bit of work.<br><br></div></div><div dir="ltr">Brent<br></div><div class="gmail_extra"><br><div class="gmail_quote">On 30 January 2018 at 10:18, Bob Jonkman <span dir="ltr"><<a href="mailto:bjonkman@sobac.com" target="_blank">bjonkman@sobac.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span>-----BEGIN PGP SIGNED MESSAGE-----<br>

</span>Are there keystone jacks enclosures designed for inline cables, eg.<br>
not for wall-mount boxes? I would hate to give a client a "fixed"<br>
cable with just a keystone jack hanging off the end.<br>
