These were from a old style bed frame that I know longer have. I thought there might be someone out there that might need something like these so didn't want to throw them a way if some one can use them so they are free you would just have to come get them. I listed for $1.00 as system with not let me list it other wise. I will take listing down once they are taken. please message and I will get back to you though the KSL message.
