Data/ Communication conduit drop

[nizak]

I’ve been asked to install a chaseway from a data closet to a new office space being built at the opposite end of the building.

In looking at the existing cabling from that space it appears each current office has (3) Cat 6 cables to it.

Owner says that the people coming to do the data work will not access the attic and need a chaseway.

No one seems to know anymore about it than that.

Would a 3/4” EMT chase be large enough ?

It will actually be easier to run a rigid material than a flexible ( ENT for instance) one just because of the poor accessibility of getting through the attic.

I can couple 10’ lengths and push them from one end to the other.

Any thoughts appreciated.

Will there be any bends in the raceway or is it a straight run?

2-90’s and one slight kick.. maybe 30 degrees

The data people will probably want at least a 1” conduit. Used to laugh when AT&T would come in and want a 2” conduit for a cable the size of a pencil. LOL!

I agree with hillbilly a 1" is probably better due to the bends. I remember doing jobs with 1.25" data stubs for (4) Cat 6 cables and maximum of 2-90's.

Thanks .. Much appreciated

It depends on the type of cable they use. The newest (I think) CAT 6E is bigger then a #6 cu. I believe.

Depends on who makes it, if there's a center spline, and whether or not it's foil vs. braid shielded, but regardless it's still a lot more flexible.

curious about the need to support the 1" EMT if it only has data wires inside. I suspect you would still need the regular support every 10ft and 3ft from boxes if you have any.
My journey man told me a while ago that the reason for greater than 1" emt (when we were installing chases for a single data wire) was that we needed the ability to get data wires with heads installed. even though they usually make the heads after pulling wires. He might have pulled that reason outta his rear and trying to give the young-un something reasonable.

Could be... copper is generally termed after pulling (heads, keystones, IDC panel, whatever), but it's very common to order fiber pre-terminated with a pull head already attached at one end.
