Description
 
Door Lock Jackshaft (DJ) style commercial door operators are ideal for shopping mall applications with lighter rolling doors and grilles. Doors used with this operator should be balanced with the ability to be manually lifted by hand in an emergency or power outage. These operators include a door lock sensor to prevent damage to the door and operator caused by attempts to automatically open a locked door. The operators are typically mounted to the wall when used with smaller sectional overhead doors with vertical or high lift and mounted to the side, or the front of the hood, when used with rolling doors and grilles. DJ operators are attached to the door jackshaft to indirectly drive the door.
