This blade foam works well in both thick walled and 7/8" thin walled blade stock. Adding a quad wrap of blade film will ensure a more snug fit in thin walled stock, but is not strictly necessary. I have used this foam with flexible pixel strips as well as the KRv2 strips and it works amazingly well with both, providing solid diffusion while still allowing that very bright and beautiful glow from the pixels ;)
