RL45 wiring component to consider.

Great price-quality ratio, significantly cheaper than the juxtaposition in a box 2 RJ45 modules or using a doubler taken when wiring mode can be considered.
Shield connections provided by a massive cast metal shell composed of a body and a cover (with captive screw). Two metal double entry cleats located face to face vs branching box for the choice of the cable entry side (or pair cables).
The front of the same format as the series © Niloé and Neptune © Legrand is removable and held by a screw hidden in the label door.
For the record for the unexpected: the mechanism can be mounted on Batibox © Legrand (or equivalent) for installation.
WARNING: The crimping of connections requires a tool: purchase (LSA-plus ~ 15 45Eu) ... or imitation of my method of sacrificing a screwdriver blade width of ~ 5mm, reground to obtain a fork 2 teeth ( land length ~ 6mm, decreasing thickness ~ 1mm ~ 0.5mm up to finish and 3mm ~ slit length in the axis and a bit wider than kerf metals).
