Safety has been engineered into the Bandlock™ 2 at every stage of its design and manufacture. A hand-
For complete safety, the locking band can be seen at all times, which satisfies design code requirements and means that the operator can actually see that the door is securely closed and locked.
For horizontal use the door is double pivoted on hinges with self-
Vertical installation includes a davit which enables the Bandlock™ 2 door to be lifted and swung clear of the hub. At diameters over 30”, lifting eyebolts are normally fitted instead of the davit, so that the door can be lifted out of the way.
