Rated 3 out of 5 by from Very strong Great valve and very strong product, can be a bit difficult to feed through your wires, so do this before your bury the conduit.

Rated 5 out of 5 by from Perfect Used this to provide protection for some outdoor network cable where it runs underground out to the garage. It was perfect for the job - the internal diameter is 14-15mm so the 7mm cable fits perfectly and it was easy to push through before burying. After burial, the cable can still be pulled through, so I could replace it in the future if necessary without digging the whole lot up.

Rated 5 out of 5 by from Easy to use, but take care Be sure you don't try threading cable that is too thick or stiff down it and you haven't got the chance to work it through before it's in place. I fed 1.5mm 3 core HITUF through it, and thankfully I did it before it got laid, as I needed to straighten both it and the cable thoroughly the ensure it fed through okay. SWA would have been a nightmare! However, it's excellent quality and very good for the price. If you have any leftover, you can blow down it and make funny noises, too.

Does this conduit comply to BS EN 61386-21

Asked by: Kevlaa

Diameter - internal or external?

The diameter is quoted as 20mm - is that internal or external?
Asked by: DiyTrev
The diameter given is external (20mm). On the inside it is about 14.5mm, perhaps 15mm at the very most.

Can I use this under concrete screed

Need to run 2.5 T&E between current concrete floor and another 60mm of concrete screed yet to go on top. This is to get across doorway as steel RSJ above and no way round. Can this be used for domestic light use floor?
