20PCS Shielded RJ45 Cat6 Cat6A Connectors, Gold Plated RJ45 Pass Through Modular Plugs, Compatible with Router, Switch, Wireless Server, Data Centre Hardware, Modem, LAN

I have used 6 of them with no issues. They work well and easy to line up wires in them.

1 pass every 10 connectors

The pass through feature is excellent. Alas, the act of crimping and plunging the tiny blades into the wires MUST be fully done, lest the blades will protrude too far for the plug to enter the receptacle. The plug could not be inserted into the receptacle on the router until I filed and pounded each one down. Sigh. F for engineering skill. It is enough work to put a tip on an RJ-45 cable, without having to do all this extra. Some users might have raised their voices or uttered coarse oaths, but I am writing this review instead. Save yourself some trouble and buy a different brand, hoping they did not all hire the same engineering team, or review your collection of files.

Does not fit cat6a shielded 23AWG Cables MAtters S/STP, S/FTP 23AWEG Shielded Cat6a Bulk is waaaay too big for these connectors - I struggled for quite some time to make a single connection, do not believe the 'upper limit' of acceptable sizes here.

Best dam thing for networking they work great
