I had a hard time with these. I even added some extra glue around it because they make me a bit uncomfortable to use. I'm not sure how well these will work out, but I hope they last a while. I bought these to setup an enclosed box for my holiday lights. I don't recommend these. Get something with longer threads. They do seem to do well for the waterproofing but the threads make me a little nervous about how well they will hold up.
