Drawstring - polypropylene rope?

[Vijay]

I'm looking at running services soon (hopefully) and wondered if this is the right rope to use? What diameter would be suitable https://www.toolstation.com/search?searchstr=34370   13254 72179 49183 16672 13574 28845  is 6mm ok??

That's the stuff I used I think they normally recommend 3/8" which is nearer 10mm. 

 

If possible pull the cable through the duct before you drop the duct into the trench, especially if there are lot of bends.

Bt normally drop off a whole roll of about one million metres with 2 lengths of duct. +1 to above. I nearly had a heart attack when I seen the 60 odd mm cable they had to pull thru a 4" duct I laid!

That 6mm one you linked to is exactly what I used.

Iv'e been buying the 6mm rolls from Srewfix, I really can't imagine that it will snap.

 

Edit to add, I've just looked at your link, I've been getting robbed

Just be aware that rodents will happily chew this type of rope to bits given a chance. If you need to leave it in place for any length of time the ends need to be capped and protected from the little b******s

Toolstation always seem to undercut Screwfix and free delivery over £10

Very good point. I was looking to leaving them in permanantly.

Do you get specific caps or is it a case of making something up and gluing it in place?

No idea what the correct method is  - So far i've stuffed wire wool down both ends and wrapped duct tape around things. I have no idea how permanent this will be.

[Jeremy Harris]

Get some expanded metal mesh, either galvanised or stainless, and roll it into a ball and stuff it down the duct.  Tie a bit of fence wire to the end of the pull cord before you do this, and feed it through the ball of expanded metal.

 

This will stop rodents, yet can easily be pulled out with the draw cord attached when the need arises.

Brilliant, thank you

Do they charge for all this?

I should have added that a screwed up ball of galvanised chicken wire would probably do the same job.  I just happened to have some expanded metal left over from making the rodent barrier around our slab insulation.

+1 to Jeremy's comment - I was recommended by the local ratman to use galvanised chicken wire and push into into rainwater downpipes to prevent them climbing up.
