I make these custom steel BARBELL LOCKS in my fabrication shop right here is AMERICA! They have a grey powdercoating, and come with a Brinks pad lock and 4' steel chain. This is far superior to the cheap plastic barbell locks available from other retailers. It requires no tools to use, just slide over the barbell, and put the lock on, takes 2 seconds! Great item to lock up your high-quality personal bars in commercial gyms. Can be chained to a rack with the supplied chain. The perfect Christmas present for crossfit, powerlifting, and  powerlifting athletes who want to protect their personal equipment.
