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

works great

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

Easy to cut to length, looks very durable

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

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

Best thing since sliced bread for diyers

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 will never use anything else on corners again. Lay it on some ram board coat it with mud stick it on the corner and trowel . Done.

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

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
