Metal pieces (Chalfont 18914)

I mistakenly was given these when buying a bed frame from someone. They didn’t respond when I reached out , so I’d like to get rid if them. I don’t know what these were originally make for but if you can use them they’re yours.

2 pieces are 10” long
1 piece is 34” high
