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

works great

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

Best thing since sliced bread for diyers

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

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

Tried taping and mudding my vaulted ceiling, it would be very difficult without this product. Great to use, I tacked one end with a screw, then tacked the other end with a screw and started in the middle with the mud and worked my way out to each end, which I then removed the screw. Would have been easier with a second person, but that was not available. The angle looks great, the product is great.

Worked as advertised. Made the project easy.

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.

Loved every inch of it, easy to form and adhered really well and never moved. Would recommend!

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