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

Best thing since sliced bread for diyers

I used this for off-angle corners (less than 90 degrees) on a cathedral ceiling. Its bad enough trying to make uniform joints with drywall on a hip cathedral ceiling without also having to correct it with nothing but paper tape. The rigid plastic strips make forming a straight joint easy. The blue line down the middle of the flex angle gives a visible confirmation for alignment and mud application. The No Coat refers to that blue line. as long as that remains visible, it is easy to keep the joint visibly straight and professional looking.

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

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

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!

works great

Worked as advertised. Made the project easy.

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

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