Common questions below.

Will the bending radius of the cable be maintained?

This all depends on the type of cables being installed & the manufactures guidelines. The minimum bending radius will change accordingly, but as a general rule, 4 x the cable diameter.
Termination space within Syncbox is a generous 40mm, like all data communication installations only poor work will effect the minimum bending radius of cables.

Can I have two power modules in one Syncbox?

Yes. But please be aware due the nature of some plug tops, a replacement moulded plug lead or rewirable plug top may have to be used. This only applies if using two power modules. These are available from TDI.

Do I require a special plug top?

Modern televisions are supplied with a moulded plug top. These often have a substantial piece of plastic at the base of the plug which is designed for cable strain. Using a standard upright socket would result in the plug not being able to fit into the in-wall tv point. Therefore we provide an angled power socket which enables the plug to be located at a 45 degree angle with ease. There is also no compromise with the available space next to the power socket for AV connections. All power and AV cables fit with ease and are totally recessed within the in-wall tv point.

If I’m using STP cable, do I need metal cased keystone jacks?

Without getting too technical, yes you can use shielded jacks and we can source them for you. But this is not required and is a common misunderstanding when using STP cable.
You should only ground the one end of the “drain wire” at the patch panel end, if you connect both ends you could create a “ground loop” and can potentially introduce interference.

What termination tool do I use, Krone tool or 110 punch down?

Krone tools are historically used for telecommunication systems, but can be use for some data outlets, however to terminate properly into keystone jacks you will require a 110 punch down tool.

How many HDMI cables can I fit down a conduit?

We have done all the testing for you, check out the results :

  • 20mm Round Conduit – No HDMI Cables
  • 20mm Oval Conduit – 1 HDMI Cable
  • 20mm Flexible Conduit – No HDMI Cables
  • 25mm Round Conduit – 3 HDMI Cables
  • 25mm Oval Conduit – 2 HDMI Cables
  • 25mm Flexible Conduit – 3 HDMI Cables

How deep is the back box?

The back box is based around the depth of a standard US J box. The back box is 78 mm deep. Apart
from the depth it is a complete mirror image of a standard UK Double Back Box.

Can I combine power & AV in one syncbox?

Yes, included in Syncbox are divides for Band I & Band II. The regulations define that once a “divider” (which comes fitted) is in place within the Syncbox installation box, the installation box is treated as two separate boxes and therefore all regulations are conformed to. Thus allowing for a in-wall tv point.

What is the depth of the cover plate, once installed in the wall?


What modules do I need to use?

Any, Syncbox accepts all euro-modules, the opening measures 100mm x 50mm.

Proximity to communications cables?

According to IET Wiring Regulations(BS 7671:2008+A3:2015).

What are keystone modules?

Keystone modules are the US versions of euro modules, but with a great advantage of that unlike
a 1-outlet cat5 euro module taking a total space of 25mm x 50mm, you can fit a 2-outlet cat5 keystone
module in the same space. We love them for our in-wall tv point.

Where can I purchase keystone modules?

We have a selection on our website.

What’s the depth behind the modules?

Once the modules are installed, it’s the same as using a standard 35mm deep UK double back box behind. (It’s actually a deeper 40mm)

What’s the internal recessed depth within Syncbox?

From the front of the modules installed in Sync-box to the back of the cover plate once fitted 40mm.

Cat5e v Cat6 v Cat6a v Cat7 v Cat7a?

Cat5e supports speeds up to a Gigabit Ethernet (1,000Mb/s) (100 MHz)
Cat6 supports speeds up to 10 Gigabit Ethernet and can be achieved with distance of 37-55 meters or less depending on the grade of the cable and quality of installation. (10,000Mb/s) (250 MHz)
Cat6A supports speeds up to 10 Gigabit Ethernet with distance up to 100 meters (10,000 Mb/s)(500 MHz)
Cat7 support speeds up to 10 Gigabit Ethernet with distance up to 100 meters (10,000 Mb/s)(600 Mhz)
Cat7A support speeds up to 10 Gigabit Ethernet with distance up to 100 meters (10,000 Mb/s)(1000 Mhz)
