Review: Great Panel Mount Plug But How to Reach Plug to Soldier - I suppose for many, the use of a spanner wrench to disconnect the plug from the base is obvious. But if you don't have a collection of spanner wrenches you can use a small screwdriver - as shown in the photo attached. The product itself is perfect for my needs.
Review: Worked great - The plastic didn't melt while soldering, and the pins took the solder nicely. Nice gaskets to prevent water from entering.

### ⭐⭐⭐⭐⭐ Great Panel Mount Plug But How to Reach Plug to Soldier
*by R***N on July 10, 2023*

I suppose for many, the use of a spanner wrench to disconnect the plug from the base is obvious. But if you don't have a collection of spanner wrenches you can use a small screwdriver - as shown in the photo attached. The product itself is perfect for my needs.

### ⭐⭐⭐⭐⭐ Worked great
*by J***R on November 30, 2024*

The plastic didn't melt while soldering, and the pins took the solder nicely. Nice gaskets to prevent water from entering.

### ⭐⭐⭐⭐ Good solid connector.
*by D***E on September 4, 2020*

A solid connector , for a good price. It uses a fine tread , makes it a little difficult to get the nuts or cap on. Would not like to do that outdoors in a freezing cold. The lanyard is a little clumsy. But for this price, I'm OK with it. Will use more of this brand.
