FGB RJ45 Cat6 Junction Box, Shielded Inline Punchdown Krone Coupler Joiner for Cat6/Cat5E/Cat5 Ethernet Network Cables, 2-Pack

Cat 6 junction box
Excellent piece of kit well detailed

Not a metal shielded junction box!
Beware. I purchased this produce because it was described as a shielded junction box and in the photograph it looks like a shiny metal case but it is plastic.Annoyingly it’s twice the price of identical items that are white plastic.Full disclosure the full description does say its plastic so my bad but im annoyed that it appears to be designed to look like a proper metal shielded case.

Reasonable product, Incomplete instructions
The box is a better than many, cable extender for solid core structured cabling, it comes with a metalized plastic mounting box to reduce RF interference at the joint.The instructions detail how to prepare the cable, which oddly doesn’t say anything about the presence of the drain wire in some types of cable – the bare wire and the foil that goes over the 4 pairs within. These must be prepared so they go into the strain relief if they are to achieve the goal of reducing RF interference, but this is completely omitted in the instructions.The instructions also don’t say anything about folding around the two strain relief tabs to provide that mechanical connection, instead it relies on wrapping a small cable tie around two holes in the plastic, the metal tabs and the now wrapped cable. Interestingly, once this is done, it does not result in the metalized plastic cover connecting properly to the ground.Double checking with a multi-meter confirms that the central plastic post for the top fixing provides the ground connection from the connector board to the case. The same post also prevents the connector board from being removed.The package and product listing details two fixing screws, however, there is nowhere to install them, nor any detailed provided in the instructions. There is also a double sided adhesive pad so you can stick the box down somewhere.If you order any form of cable coupler like this, don’t forget that you will need a Krone style punch-down tool so that you can terminate the cables in the insulation displacement connectors within the adapter.note that this type of box can only be used with solid core cable, not stranded cable as is used in a patch cable, for those, use the plug-on RJ45 to RJ45 couplers instead.In all cases, make sure you don’t exceed the maximum cable lengths for your structured cable run, typically this is 80 Metres, allowing a 10M patch cable at each end, making the total length of 100M

Fully FTP compliant
These junction boxes are constructed of a lightweight conductive metal shell and a PCB for punching down the 8 cores of an FTP ethernet cable. They also have a FTP bond point on the inlet which is bonded to both ends via the PCB and to the outer casing too, so preventing EMF interference throughout the installation. There’s no reason UTP cable can’t be used with this junction box of cause but it would be a bit of a waste to not take advantage of the shielding capabilities if available.The kit also comes with 3M pads and self tap screws for mounting the box to joists. They’re designed for indoor use but can be used in conjunction with a weatherproof box for CCTV installations. There’s nothing that says it is PoE compliant but I can’t see why they won’t be given the low voltage transfer of this type of install.There is a very low level instruction leaflet in the packaging although I’m sure most people ordering this sort of product won’t need such guidance.
