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...

The 12 Mil Crawl Space Vapor Barrier, GuardianLiner™ is the ideal covering for my dirt floor crawl space. It arrived on time, it is easy to work with and it is both economical and tough and is of better than average construction. I plan on buying more when it is time to finish encapsulating my crawl space.
