Good afternoon, We're in the process of switching some of our locking cases over to the Kwik Case system. I'm reaching out to see if any libraries have a Kwik Case magnetic detacher (unlocker) that is no longer being used. (Picture at http://www.gresscoltd.com/magnetic-detacher.html.) Please get in touch with me so we can talk price and details. Thanks, Matt Matt Church, Library Director Berkley Public Library 3155 Coolidge Hwy.
