The 42 was and is a must for installing the vapor barrier. I am so glad I did my research and found it. I can see where the 42 protects the plastic from sharp objects. It also helps to keep the dirt from getting all over the top of the plasitc during installation. Awesome product. Thanks Randy

I used all your products including the 42 550. I used the 42 in the event 88 was identified as a problem. I will always use the 42 on future jobs. Even a very well prepared crawl space will have small rocks and gravel that cause no problem when the 42 is used.

I really liked the 42 it is the first time that I used it on a dirt crawlspace.

I was pleasantly surprised how strong this is. I tried to tear it or poke holes in it, but I couldn't. I put it on top of rough edged stone, before I laid down the vapor barrier. It's much better than any of the alternatives I was considering. I'm very satisfied with it's performance.

Amazing product and exceptional customer service
