I chose this 9mm peg to use with a K&M folding metal stand, to safely hold my wooden Irish flute. Ordinary flute pegs are too large in diameter for this purpose, but this is perfect. I already have a similar set-up for a clarinet.
I have numerous K&M products and am always totally satisfied with them. If one contacts the company for any suggestions, they are very helpful and even send technical drawings to assist.
