Time Master Inc. (TMI), Topeka, Kansas

TMI series 2400, modern - manufactured in 2010. This is one of the electronic readout time locks. These time locks have never been as popular as the concurrently produced all mechanical time locks by this and other companies. Perhaps it is because of the need for annual battery changes or the lingering doubts about the reliability of the time lock should the batteries or some electronic component unexpectedly fail. According to the owner's manual the lock is designed to go off guard under these eventualities, but the perception is hard to overcome for what is essentially a very conservative industry. 4"w x 3.5"h x 2.5"d.  file 155
