Grabber 318111 No-Coat Ultraflex 325 Flexible Corner Tape, 100 X 3-1/4

I used for a cathedral ceiling, very happy with the result. It WILL follow the imperfections of the drywall

This is the stuff to use on outside and inside corners. LOVE it!

We had less of a mess with it easy to put up. Cut back on how much you had to sand. Got the job done faster

Worked as advertised. Made the project easy.

This is an amazing product. Does what it says. Just make sure you do the skim coat on the edges after setting

This will definitely get you out of prepacking off angles. This is sometimes wildly expensive on Amazon though. Should cost about $45.

I use this and the 450 for all my outside corners. Its super fast and really easy to install. The finished corners are really strong and dont chip or flake off when hit like traditional corner beads. The only drawback is the specialty tool required to make the installation go faster. Still the best no coat product Ive used so far.

I like this tape. The description says you can use it for inside or outside corners. Its rather pricey so using it for inside corners is wasteful in my opinion. One thing I found is that in order for this to stick to the wall properly, you need to ensure that the wall is filled in behind the tape fully. You cant get by with one edge not aligning perfectly with the other edge. This takes some getting used to but after you play with it a while, youll get the hang of it. I did use this on angles less than 90 which I feel is this tapes forte. My opinion is it beats old metal corner bead.

Easy to install and durable to use and mud -used it on angled ceilings and adjusted to the variable pitch

works great
