We have a limited number of lockers now. Each unit is 12 inches wide (opening is 9" wide), 11.5 inches tall, and 17 inches deep. Each one can be locked by your own lock. While no one here is going to mess with your stuff, we do recommend using a secure lock if you wish to guarantee that no one opens your locker.
We have not yet discussed a monthly rate for renting these lockers.
