Jail Vault Door

It's a jail door... slides open and slams shut... hand crafted from sturdy metal to fit the jail cell of your dreams, on sliding rails no less..  (it might be noteworthy to mention that although this door will keep customers for your escape room in, until they find the clues to open it... they may not be suitable during a zombie apocalypse) Also, these doors can be modified to fit a particular room design... so a medieval dungeon? Evil scientists lair? overly excitable rabbit, with huge gnashing fangs? oh, um, no... run away!! run away!!
