Review: Conduit appears to be smooth inside to allow cable to be pushed through 20m length - This review is for the 1STec 20m 20mm External 14mm Internal Underground Cable Conduit Ducting. I found the ducting to be tough and durable and fit for purpose to be used externally. I fixed part to a wall using 20mm P clips purchased elsewhere and the rest was buried underground with part run along fence on the ground. I needed it for runningh ethernet cable for electric gates intercom - importantly it is possible to push the cable through the conduit by hand but you have to have the conduit pulled very straight with one person pushing the cable from end. It helps if its held on a downward angle as well and the cable slides through with a bit of shaking every now and then as the conduit appears to be smooth enough on the inside.
Review: Good alternative to armoured cable - Used this when replacing a pond pump which has the cable running underground. I have used armoured cable before but this means having a join, underground, close to the pond. Getting a waterproof join underground is not impossible, but it is difficult. In this case, I removed the plug and threaded the cable though. It will not pass through long lengths so I used 3m lengths sequentially and butted the joins up. Then I buried it. It is working fine so far. I suspect it is weaker than armoured cable so know where your cable is buried and take care when digging in that area (turn off and unplug to be sure).

## Features

- BURY CABLES UNDERGROUND - These cable protectors are ideal for burying wires in mud sand clay concrete stones gravel rubble or under grass where an unprotected cable would be likely to suffer from abrasion damage from sharp objects
- SUITABLE FOR MANY USES - These IP67 rated outdoor use cable trunking tubes can be used to duct BT Telephone Virgin Media Freeview Freesat Digital TV Aerial leads 12V low voltage Garden lights fish pond pumps power gates or garage door cables
- EASILY CUT TO LENGTH - Cable conduits can be easily cut to shorter manageable lengths when doing long cable runs. You may find it easier to feed a cable through many 5 metre lengths for example taping the joints together afterwards
- USE WITH DRAWCORDS - You can use a cable to install a draw cord when planning your installation. This can allow the ducting to be set in concrete or buried underground allowing one or multiple cables to be pulled through at a later date
- INDOOR OR OUTDOOR USE - Conduits are handy for outdoor or indoor use allowing for serviceable cable guides where cables can be replaced under wooden floors, drives, pathways, sheds, loft spaces, wall cavity and other hard-to-reach places

## Questions & Answers

**Q: When used for protecting mains electricity for outdoor lighting, how deep should the conduit be buried (Hituf cable)?**
A: Deeper than you are likely to cut it with a fork or a spade. How about putting a row of tiles or bricks on top of it to give it protection?

**Q: what do you require to join together for long runs, cant seem to find any glands, i see you taped the joints , but then this aint water proof ??**
A: I used these connectors from Amazon to make connections between several 10m lengths, so you could try these - Tower Heavy Gauge Conduit Couplings 20mm:

**Q: Is it twin walled? What temperature range can it handle? Thanks**
A: It is not twin walled but comprises a surface of deep raised rings which offer good insulation and flexibility. There was no advice on temperature range. It is a well made and good quality product. Probably worth asking the supplier for more info.

**Q: Can this be easily cut lengthways to cover an existing cable that I've uncovered in my garden?**
A: Wouldn't have thought you'd have a problem. It's quite flexible. I used a sharp knife to cut into mine and was easy to cut. Should be able to open it to cover the cable in my opinion.
