10pcs PG9 Black White Plastic Waterproof Cable Gland Connectors Joints 4-8mm.

I have received these items in less than a month, after the purchasing. I was anxious to receive them because they are very important part of a project that I have for a garden electric junction box. I will make holes at the side of a waterproof plastic box and insert electric cables through these connectors, assuring that water and humidity will be kept out of this junction box. I was looking for a solution for a long time and after I have seen these pass-through connectors on Ali, I immediately know that they were the best way to solve it.
