This connector seems well made and was the only one I found that was screwed on instead of being loosely secured with a rubber cap. However, it is very small. The screw holes are so small that two out of the three stainless steel screws I used to fasten to the deck twisted off, even though I drilled pilot holes. 14 gauge wire for a long run up the mast was to big to fit through the plug. If you have your precision screw drivers handy, it's a very good product.
