Pot clips - how do they work?

[alannanoelle]

My new phal is about 4 feet tall, and when I repotted it last night, it is a bit looser in the new bark medium than it was in the old moss. It sways a bit...I had to lean it against the wall to keep it from falling. I read on a post below that pot clips (or rhizome clips) work to help hold the plant up. I am about to make an orchid supply purchase, and I noticed that there are several different sizes and types of pot clips and rhizome clips. By looking at them, I can't figure out how they work. Can someone explain to me how they work? Also, what size and type would you recommend based on the size of my plant?

Thank you!
