    I bought this item as I need to extend a ethernet cable that fed my workshop, and it was ran through a wall and secured where I couldn't re -route it. I cut the original cable and used this to join it in a LB that fed the workshop from my home. i filled it full of die-electric grease before inserting both ends and sealed the LB. Does exactly as its designed and fint in a 3/4" LB finely.

    If you run out of length and need to continue this is the easiest extension out there. Just connect the two cords with this and you’re good to go!

    Both sides seem to be held in well but have no problem letting the cables slide out when needed. Exceptional quality compared to competitors with the same price!

    Better to connect two cords to make the needed long one than to replace those with an additional lengthy one. Saves money and easy to dc from another location than the back of the router when necessary-

    Works perfect for a low price. The speed of my internet didn’t change or get interfered from the block so if you want a cable connection for your ethernet cable this is a good choice!

    Had to move my router farther away from my pc. Instead of buying an expensive long ethernet cable, I bought this and a cheap (short) ethernet cable. Works great and havent lost any speed from my gigabit internet.

    Worked precisely as needed. Used it to daisy chain 2 shortened ethernets (instead of buying a whole new cable) and it worked exactly as needed. No complaints.
