Flatter plug?

The plug for my Openreach junction box (the one before the router) is so big that it is causing an issue with furniture.

The plug says it is:

- 100-240V

- 50/60Hz

- 6.0W

- 12.0V

- 0.5A

Has anyone replaced this plug with a flatter one? Is there an option on sale?Screenshot 2026-09-02 at 13.13.47.png

Re: Flatter plug?

that is not just an ordinary plug but specific to your ONT.  You could connect a  2 way trailing extension and connect the ONT plug to the extension

That's not going to be suited to the challenge I have, sadly. It's a shame that the plug is so big. It's causing a big issue.

It's not just a plug of course - it has a transformer in it with the voltage output required by the ONT. There won't be any "flatter" versions available I'm afraid.

Re: Flatter plug?

Just for future reference, the box is called an ONT (Optical Network Terminal).  The plug is actually a low voltage PSU (Power Supply Unit), rather than a simple plug.  I have the same type and I've just measured it.  It stands 1" higher than a normal plug, so I'm not sure how that is a challenge.

If you can be a bit clearer about what this "challenge" is we may be able to offer a better solution.

Get a competent person/electrician to extend the cable so that you can plug it into another electrical socket or get Openreach out to move the ONT to a different location where size of the plug won't be an issue. It will cost you about £150 or more to do that.

Re: Flatter plug?

With at least most of our ONTs using a common socket size (unlike the SmartHub 2) you could change to a 12V power adapter that runs from a regular UK 3 pin plug to a figure 8 or clover-leaf socket.  With just 2A being required, you'll be better off getting a 'quality' switching supply, but they are easily available on-line.  Cannot stress enough that the power supply needs to be designed for either IT or medical use, so don't just get the cheapest one going!  *I would not consider this type of adapter to be pet friendly - due to chewing!

You can also get compatible power supplies that are just flatter - probably about twice the height of a standard UK plug!


I only learn by making mistakes and owning up to them - boy do I learn a lot!

Probably easier to just rearrange your furniture
