Christmas tree fasteners are used to permanently attach plastic vapor barrier to the foundation walls of the crawl space. These plastic retainer clips got their start in the automotive industry and was quickly adopted by crawl space companies and DIYers to make crawl space vapor barrier installation simple and effective.

We recommend using our 2" Butyl Tape in conjunction with the Christmas tree fasteners to secure the vapor barrier to the foundation wall.

    I installed mine through the plastic and butyl tape into 2”foam board and they hold tremendously!

    I was worried these wouldn't work in my old crawlspace walls ... no need to worry. They are holding perfectly in less-than-ideal concrete! Having small hands, I used a rubber mallet to tap them in (GENTLY!!).

    Great and easy to use. I also made a small flap at the ends and was able to double the holding power to the vaper barrier. Only four stars because i didn't see a fastener available that could hold my foam board. ( not long enough)
