I'm doing a small phone/data wiring job for a new office inside a big warehouse with 30' ceilings. The new office will have a drop ceiling and steel studs. Otherwise there is nothing in the ceiling to support j-hooks. I don't want to attach anything to the grid or the grid hangers.

Does anyone know of something that will attach to the top of the steel studs to hold the cables. I found this which I thought I can screw to the header but I think the cables will be too loose:

I don't think caddy has anything comparable.

I would just use regular J-hooks with sheet metal screws around the perimeter of the office area on the walls.

There is a bracket that holds the wires out away from the studs and drywall for pre-wires. I thought it was a Caddy product, but after a quick glance through their catalog I didn't see it.

Here is a link to a product sheet of what I was referring. It is not the best solution but for a small job it is not bad. Just what ever you do, use pliers to bend it in half. Don't crush the cables in the process.

I can't imagine that Caddy/Erico doesn't already have something pre-made.
Here is an image collection of existing caddy fastners :

I used those Arlington plastic brackets. I had to attach them to the top plate of the studs to hold some cables. You are right, they do not hold the cables very tightly as they are made for holding NM cable.

In a manner similar to the method used to tie the ceiling support wires to the steel rafters 30 ft in the air. Twist the stiff wire (like ceiling suspension wire) to the rafter, and leavce it long enough to be reachable, but no on the ceiling tile or grid.

Tie your cabling onto the hanging suspension wires and be dun!

I can't imagine using the Cable cat posted above that is made by CADDY. It -by design- puts the weight of the cable on the ceiling grid. Exactly what you are trying not to do.

I agree with ttech, I am surprised that caddy even sells any of them. I guess someone has to buy them.

Right on their data-com product site.

I agree with the weight on the ceiling, but my intention with posting wasn't the "on the grid" install.

Rather screw it to the top of the stud, so it stands off vertically.

I was not pointing my comment at you. I was pointing the comment at ERICO.
It would seem that it would make an install not pass an inspection. Especially if the Inspector pays attention to the last sentence

"300.11 Securing and Supporting.
(A) Secured in Place. Raceways, cable assemblies,
boxes, cabinets, and fittings shall be securely fastened
in place. Support wires that do not provide secure
support shall not be permitted as the sole support.
Support wires and associated fittings that provide
secure support and that are installed in addition to the
ceiling grid support wires shall be permitted as the sole
support. Where independent support wires are used,
they shall be secured at both ends. Cables and raceways
shall not be supported by ceiling grids.


It is a very Grey area because apparently it is not really clear in Section 800.

No problem, I didn't take it as such. :toast:

I was agreeing completely, but pointing to the web-site, incase you didn't think it was an actual Eric/CADDY product.

You are right on about the inspection/inspector, for sure.
That would, or at least shouldn't ever fly!
