Ordered these to replace another set of the same item which broke less than a year later. Interchangeable mounting bases worked fine for about a month and then broke. They reportedly weigh 75 pounds each, and two of them supported a drawer that weighed well under 20 pounds. So two orders of these sockets were used on the same drawer and both broke after a short time with light use. This is simply unacceptable. I replace them with steel and do not advise anyone to use them to repair their drawers.
