ᐅ Installing a cable duct (Ytong blocks with plaster and drywall)

Hello everyone,

I would like to install a cable duct for the telecommunications connection in the utility room. A cable should be routed from the main connection through the duct to the router, which is mounted above the door. The load is relatively low, but I am wondering what the best way to attach the cable duct would be. The surfaces are a plastered aerated concrete wall (plaster thickness 1–2cm (0.4–0.8 inches)) and a drywall partition (double-layered plasterboard). I have considered attaching the duct with double-sided tape or silicone, but I am concerned that more plaster might come off the wall when removing the duct later on...

Best regards

You’ve actually already answered your own question. 🙄
Mini cable duct is also available with the corresponding adhesive tape already applied, ready to use from the shelf.
Maybe that’s the lesser evil.

There are specialized anchors both for aerated concrete and hollow blocks.

In aerated concrete, I either screw in the screws by hand or carefully use a cordless screwdriver. This holds better than most anchors. And if in doubt, you just use two more.

Würth now also offers special screws with rather coarse threads.

In the utility room, I would use at least a 40x40 cm (16x16 inch) duct, preferably 40x60 cm (16x24 inch), where you can fit plenty of screws.

If I understand correctly, I believe this is not about how to fix the duct in place, but rather how to remove it later with as little residue as possible. Right?

No one really needs a small cable duct; it’s better to use a conduit instead. And if it’s a proper cable channel, it makes sense to screw it in place.
