Before I found it. I used masking tape which helped a little but was too flexible. These strips provide enough stiffness and adhesion to significantly reduce tearing. With five in a pack, this is going to take a long time. With this tape and some fine tuning of my miter saw I can achieve 90% accuracy and quality on a table saw and sled. Some reviewers complained that the sharp edges and thickness made it difficult for them to slide across the table saw. Well, it's not made for a table saw, and if you want a beveled edge you can always use some sandpaper (I tried cutting at an angle but it looked pretty sloppy). And the color matches my Dewalt saw. Beautiful attention to detail.
