How to make a cable entrance in the data closet? Boleslaw Ciesielski 04-12-05

I hope this is not a (too) stupid question. I am running some wires in
my 2-story house and setting up a "data closet" in a closet :-) The
closet is on the second floor, so there will be a a whole bunch of
cables coming down from the attic inside the wall and then to the patch
panels etc.

But how do I make a clean entrance for the cables from the wall to the
closet space? Do I just make a big hole in the wall and have the cables
go through it? It's a standard drywall. Are there any products made for
this purpose? Maybe a kind of grommet or something? I would also like to
be able to add more cables later.

Thanks for any ideas,

Bolek

I would run several conduits down thru the wall to a large junction box
mounted flush with the wall. you can then use a cover with one or more
grommeted cutouts along the bottom edge to bring the cables out of the
front of the box. The conduits should have plastic bushings at both ends
to protect the cable.

I don't know how many cables you are going to pull, but I would start with
at least 3 2" conduits and a 10"x10"x4" pull box. Leave at least one conduit
empty (except for a pull string) for future expansion.

I wouldn't use a patchpanel, or rather, I'd make a patchpanel from
keystone jacks in 6up wallplates, trimmed into a double or triple
gang electrical box with the back/side cut out. Very neat finish.

If you really want the patchpanel (often mounted vertical),
you can make a neat wall penetration with a clamp-on LV Caddy
box and an empty Decora wallplate.

The standard for wiring new homes is to use a Leviton or other
lockable patch-box surface mounted directly over a hole in
the drywall. I think Home Depot carries these.

Thanks to both of you (Bob and Robert). Have one question though.

I am not sure how this looks like and how to find it. Can you point me
to a picture of something like that? Perhaps at

Thanks,

If the cabling is just for data networking (i.e. no voice, video, etc),
I would stick with the multiport faceplate idea. You can get
double-gang faceplates that will accommodate 12 inserts. If that's not
enough, you can add more later.

If you're considering a Leviton structured media cabinet (or similar),
you can also mount them "in" the wall, so that the front is flush with
the wall. Here's a link to the page for the 14" cabinet.
