These are super easy to use. I had never used these before and had no problems using it on my Christmas lights cords. Thanks for the excellent blog posts and videos.
ordered the female ends by mistake. called customer service and they got my male ends in the mail the same day. got them 2 days later and was able to complete my display on time.
We took a 100 foot strand of C9 cord and used it in three separate places on our roof. It was very easy to use these male end plugs to create each cord.
the gilbert plugs are very easy to use and quick to install. you can even use the lip of the cap to hold the plug under the lip of the flashing.
