Cleat --used for securing stuff by winding a rope around it (New Costessey NR5)

Hello everone
Thanks for reading this.
I am hoping someone has got some unwanted cleats lying in a draw or in a shed somewhere. They need to be 15cm/6 inches long or bigger. I'm going to use them to rope down some roofing sheets with stout rope over cut logs for a firewood winter store. They can be tatty, made from metal or plastic.
