Good afternoon: I have a couple of questions regarding your library's door locks. 1. Do you have any electric locks in your building? If so what brand and do you like them? 2. How frequently do you change your locks? Thanks in advance. -- Amy Knepp, Director Oscoda County Library <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
