Product I usually use for my network installations. Qualities: double take, code visible colors, excellent contact (never had a defective product), unbeatable price for the cat. 6. Some criticisms though: - A poor design (we are far from Legrand Mosaic) - The arrival lids cables are too visible on the sides. - Case of mounting holes do not allow to adjust the position so it must be careful when drilling the wall (A peak for pro equipment!). - The adjustment of the socket relative to the housing is ... at random! No mark, alas, and we must tighten more facade to see if the installation is good, then redémonter to rectify. - The position of contacts on the back of the grip (online 3 cm) requires some skill to meet the constraints of wiring cat. 6: hard not untwist pairs more than 13 mm. - No valve to seal the unused outlet when in a cable. - The socket marked "No. 1" is the left one, the "No. 2" the right one front view. It would be nice to indicate the terminal block. Most of these defects could easily be corrected by the manufacturer. We would then have an unbeatable product. In the state, I recommend this product except for the numerous cabling where it is important to win 5-10 minutes on each outlet. Final Note: Remember the clip or KRONE 110, strictly necessary wiring to these jacks.
