Rated 4.9 out of 5 by 24 reviewers.
Rated 5.0 out of 5.0 by Did what they were meant to do. Helped make short work of insulating under my house, which had no prior insulation. Just make sure you know which size you need in advance, and order an extra box or two, just in case. It's no fun to have to stop in the middle of a job and run back to the store! July 27, 2015
Rated 5.0 out of 5.0 by The best product ever! After reading the reviews of these support ties, I realized that I could fix the existing and add insulation under the house. (it can get expensive to have a professional do the job) The supports were very easy to use and I could do it with one hand. I know I probably used more than I needed. I just never wanted to go under the house in such a small crawl space again. These support ties are a must have when putting up insulation! BTW I'm female and hate bugs October 16, 2014
Rated 5.0 out of 5.0 by it works They do the job they were meant for. It would be costly and time consuming to put up wood slats to hold the insulation under a floor. Last owner did not put anything to hold the insulation up and most of it was on the grown. I put new insulation in with a higher R value. January 21, 2014
Rated 5.0 out of 5.0 by Works great for pilot bits I'm an electrician and I've never used them for insolation I use them because there so skinny and if you put them in a drill it will go right through wood. You will never find a pilot bit as small as these rods. And getting 100 lets you have bits for a long time. January 20, 2015
Rated 5.0 out of 5.0 by tensile wire It was used to make door latches for transport cages, good stiff wire with spring like capabilities. It's a little tough to bend but had great outcome. (also works great for insulation-it grabs and hold great). June 16, 2015
Rated 5.0 out of 5.0 by Excellent product for keeping insulation in place. This product is easy to use and installation is a breeze. March 18, 2015
Rated 5.0 out of 5.0 by Works well They work! We looked for this specific color at several stores and found them here. April 28, 2015
