The pins worked exactly as described and made a tricky job much easier. The large heads made it easy to hit the mark, as well as being a large surface to better secure the vapor barrier. The quality and design was very good and the price was much less than a tapcon. This was my first crawl space experience (hopefully my last), but the products purchased were perfect and the tech support was professional, courteous, very helpful.

The pins are very strong and durable.

depending upon the mil thickness, I use X amount of pins. I research everything and theses wont degrade for about 100 years. They fit a 1/4" drill hole perfectly and when i drill into mortar, I might add some Lock-Tite. They're perfect

After shopping locally and finding noting but thin plastic sheeting, I found Crawl Space Repair. Everything about my Vapor Barrier is amazing now. This was a great DIY project once I ordered the right products. Thank you for helping me keep my family safe...

Used it for the support of 15mil vapor barrier. We put it approx every 12" although you can space them further we just had plenty. There is no removing them so make sure you drill deep enough to install them all the way in.
