Works great for sound deadening install!
Size: 3 Pack
I recently put Kilmat in my van I am converting. I thought I wouldn't need to get rollers to install the sound deadening mat in my van but I ordered these anyway. Why not, 3 rollers under $20.00 and I could return them if I didn't like them. Well I ordered this roller set. I was able to put the mat on and smooth it with my hands but these rollers really helped flatten out the sound mat to get better adhesion, especially where I overlapped the seems. The rollers were more necessary than I thought. They are very sturdy and work well. They do not feel cheap and I actually liked them quite a bit. The rollers have smooth function and leave little lines in the mat where I used them. This was very handy as it let me know where I had already used them. It was nice having 3 sizes. The big roller did not fit in some of the curved areas, so I used the smaller rollers. These will work well with sound mat that is thicker than the Kilmat as well. If you are installing sound deadening mat, you should purchase these. I saw other rollers that were more money and didn't have multiple sizes. This was a good purchase. I will try to add a picture to help with visualization purposes soon.

These mat rollers do a terrific job and worth more than the listed price.
Size: 3 Pack
This product is AWESOME!! to be sure. The 3 sizes you will come to appreciate, as I did. They have some 'heft' to them, and the ribbed rollers are far superior to the flat rollers. I just finished installing sound/thermal mats 'under' the rear speaker shelf of my '71 spiffy GTO. Tomorrow, I expect to do under the rear seat, and I am sure happy that I have three different size quality rollers. Buy these, you can't go wrong.
