Description
 
Door Lock Hoist/Jackshaft (DHJ) style commercial door operators are ideal for shopping mall applications with heavier rolling doors and grilles. The operators provide a floor level chain hoist to ease manual operation in an emergency or power outage. The 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 larger sectional overhead doors with vertical or high lift and mounted to the wall, or the front of the hood, when used with rolling doors and grilles. DHJ operators are attached to the door jackshaft to indirectly drive the door.
