We installed underground utilities to a new mall scheduled for completion this summer. Prints called for 2" conduit for CATV and despite my bringing to the attention of the site GC's super the CATV standard calling for larger pipe no OK could be obtained to size it up and get paid for it. End result is a 1200 foot run of 2" with no pull holes (only 2-90 deg bends though).

What is the longest of this type pull you have ever successfully done...think this will fly? The pipe is sufficiently larger than the cable, but the logistics of pulling hard thru 2" are tricky...rope size,etc.

Lack of pull holes was due to sacred "buffer zones" around the project which could not have structures showing. Common here is 4" conduit with pull holes every 4-500 ft. I have the print to protect me but still am concerned about the difficulties the engineering (driven by budgets) has created. The difference in 2 and 4 inch would easily be absorbed by the owners of this project but we couldn't afford to eat it twice(it exists in a slightly shorter form elsewhere on the site).

Ouch! 2" is a big mistake. Do you even know what cable will be pulled in there? It's going to be flooded hardline (solid sheath) probably nearly 1" in diameter. If someone actually does manage to pull it through I can't see how it will survive without damage.

There is a reason for 4" and handholes. Those stupid engineers think all CATV is RG-6!

It's PVC all the way, and yes, I believe the cable would be hardline, it always is. Apparantly the money guy for the tenant's GC for this project came and met with the planner at the local CATV and told him what he had in mind, was clearly told "no way" on 2". A second conversation was had over the phone where the money guy said that's what he had instructed the engineering firm to draw for bid purposes, was again told "no way". At any rate, that's what we carried in our bid(you can't get bid jobs around here by being generous) and I was unable to generate any interest when I started the job. Diggers 200 feet of trench ahead of me and ready to backfill, this ain't the time for engineering.

I never have fully understood the thinking of the non-construction savvy money guys who try to keep the costs down despite expert advice not to cut certain things.

All I want to do is get a mouse thru, pull a 1/4" nylon rope back thru to satisfy our contract.

BTW, I am not the owner, just a tool wearing foreman. These guys don't want to here from me.

If the 2 90s are at the ends they might be better off to cut them out, pull the cable through the straight section and put them back. When FPL pulls long service laterals around here they seldom put in the stub up until the wire is in. Not really Kosher but it works for them.

NO ROPE YET! With 2000' you had better start pulling some in as you go. You might find it really hard to blow, suck or otherwise, get a 1/4 line in. You might be able to suck a 1/6th through, and pull the larger later, buy just a little wetness will wieght the line down.

Seriously, you might want to add some Chisty boxes. They aren't structures IMO.

Your going to need a compressor to blow a line through that far.

A large one....

The type of "mouse" I've found to work the best are the Duct Projectiles

See bottom of page at

Best of Luck to you !

Don't you have one of those new 1200 ft. fish tapes. That's the mentality you end up working with. I had a company send out a compressor once ( a small one, wouldn't inflate a bicycle tire) to blow lines with. Then they wanted to pull 930 ft. of 750 with a 1/2" lylon rope. Spent 2 useless days trying in heat of over 100. I figured our loss at about 3k. We were really saving the money. The thing that I can't figure out, is how idiots stay in business. Maybe it's true that God looks out for fools, children and drunks.

We use a used plastic shopping bag for the mouse, and vaccuum in polyproplene string that comes 10,000 foot in a box or bucket. Works like a charm, even with other cables or conductors in the conduit.
