Super durable, feel heavy duty!

I purchased this to gel my Aputure 600D lights, which isn't very often, but I wanted something large enough in case I needed it for as 1200D or use color gel on a 1200X. I was worried this could be fragile and susceptible to bending in transport, but this thing is built extremely well. It has a solid thickness to it while remaining light weight. This will also work well on C-Stands!
Very useful

I bought this to use it with rosco diffusion papers. I was fearing it would be heavy, but I'm glad it is not.. It doesn't feel cheap and have some weight but not heavy for a lightwight stand to hold. It's not large or huge but it's not detachable, which I already knew before i ordered, makes it a bit tough to transport. Overall it is great and a must in my kit.

question
Does this come with a stand?
No.. You would need a stand and a grip head

question
Matthews Diffusion Frame - 18x24 - Knife Blade How do I mount this? What kind of fitting(s) do I need?
To mount just use a standard grip head. You can skin the gels on it with snot tape or just use clamps.
