cable ducting without pulling rope installed

[Jdsparky]

Hi,

Just wandering what to use to get an armoured through a new duct which has been installed prior to me being on site without a pull rope.
Longest run is about 30 meters with probably 2 bends and is about 3 inch diameter but is the flexible type with ridges.
Will rods go that far and round bends especially with it being the ridged type of duct?
I have seen the continuous rod on a reel that bt etc use, is this my only option to hire one and are they flexible enough etc to go round bends of this size etc?

Thanks

How tight are the bends? Cobra with a tennis ball or small Coke bottle on the end will slide straight over the corrigations

rat and a ferret. no problem.

It's a small mammal with a slender body that is good at fitting down ducting. Long lead required.

Lol :rofl:

We have a ball attachment for our Cobra that would do that easily , I think they do a 6mm version which may help with being that bit more flexible .
Also as suggested a decent road compressor and a carrier bag should do it , but I prefer fishing line instead of string .

Once had a car park lighting duct with rope in but blocked, local labourer fetched his ferret in with a ferret finder and found where duct was blocked in about 10 min.(crushed by rocks compacted by JCB )

Hi,

As Lee and Martin have said, Compressor and placcy bag, I've used this on more than one occasion and it's always worked.

Regards.

Are you talking about standard rods?...

If so try drain rods instead.

Maybe use the brass wheel attachment too

30 meters is pushing your luck especially with corrugated wall ducting. You could try but you'd need to use an end attachment that looks like an egg whisk.

I saw something just like that on telly a couple of weeks ago.

It was a program about Instruments of Torture and this thing had a screw that made the diameter expand when turned.

I'll leave the rest of it to your imagination ...... :devil2:

No, but I've seen them used on car body repairs. Nice clean cuts VERY impressive.

Yes, I've used them for exactly that .
Cutting sills out on the old Fords etc, worth their weight in gold for cutting.
