Arch-Flex 333 is the first arch product that comes on a roll. Designed for all radius curves, Arch-Flex also resists dents and paint chipping, cuts easily with a utility knife or scissors, is applied with all-purpose joint compound, and will not rust. The tape is manufactured with patented tear strips to create easy straight-to-curve transitions. To apply, measure entire curved application by using Arch-Flex 333 as a tape measure. Cut to measured length plus 1 in. Fold Arch-Flex 333 completely in half at crease and remove tear strip by folding along perforations and pulling. Leave tear strip intact where a straight-to-curve transition is required. Apply all-purpose compound to corner. Starting from one end, press Arch-Flex 333 firmly into compound. Re-cut length to fit if needed. Wipe down compound and adjust to a smooth curve. Apply second coat immediately and let dry. Apply final coat, let dry, and sand.

Rated 3.1 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by A must have for arches Easy to use and saved me a lot of time and work on my archway project. September 2, 2014
Rated 2.0 out of 5.0 Hard to use and changed to plastic after attempting use. Bought four boxes and only used one and changed to another product. April 17, 2012
Rated 5.0 out of 5.0 by Really Good Stuff This is a fantastic tape that follows curves without having to cut slits in the tape. It makes life so much easier and work faster. April 6, 2015
Rated 1.0 out of 5.0 by Worst Stuff Ever Ignore the instructional video. This stuff does not glue on, nail on, staple one -- it doesn't stay on at all! Ended up tearing it out and using something different. Don't waste your money or time on this product. February 15, 2014
Rated 1.0 out of 5.0 by Not what I expected The product has a good plan however it fails to come to fruition when using on arch ways. Once the tabs are cut they do not want to remain laying in the compound without attaching. February 21, 2015
Rated 4.0 out of 5.0 by easy to use it was easy to install and I received it faster than promised May 27, 2014
Rated 4.0 out of 5.0 by Worked quite well with only minimal issues After reading several reviews about the edges of this flex corner bead not wanting to "bond" to the mud, I was admittedly concerned that I would have similar issues. I believe one reviewer even went so far as to say they finally removed this bead and went with something else. Needless to say, I was expecting problems from the beginning. After applying a thin base-coat, I simply removed the plastic edge strips and applied the bead, then put another coat of mud on to cover the tabs. It bonded fairly well, with only a few tabs coming away from the mud\wall. I simply grabbed my staple gun and stapled those few rebellious tabs down. Once that joint compound cured out, I sanded and applied another coat. After that cured out, I sanded and applied a final coat then sanded, primed and painted once it dried. All in all, I'm quite pleased with the project and the results. The only real issue was the join point between the metal corner bead and this plastic corner bead didn't mesh up perfectly...but nothing a little mud couldn't fix. My only qualm is the both the product box, that the corner bead came in, and the sales receipt\invoice, plainly stated this was a free sample from the vendor. I wasn't too particularly pleased at the concept that I paid Home Depot good money for something that cost them nothing. Oh, well. C'est la guerre. If you want to dance, I guess someone has to pay the piper. October 14, 2014
