The box houses a mechanism arranged such that certain keys are wrapped when others are removed. Its simplest form a control key is trapped until all other keys have been returned to their respective exchange box locks and turned to their trapped positions. The control key can then be removed, wrapping all other keys. Number of such key-exchange boxes can be kept in sheet steel door enclosure box. The design of this box has been tested at CPRI Bangalore and it ensures IP 55 protection Door Lock Type DT1 & DT2 http://www.msenterprisingengineers.co.in/door-lock-type-dt1-dt2.htm http://www.msenterprisingengineers.co.in/door-lock-type-dt1-dt2.htm Sat, 07 Dec 2019 00:00:00 +0530 This interlock consists of two separate parts. One part is the basic interlock fixed on a Brass / Aluminium Body housing the mechanism. Another part is a sliding Bolt. When the sliding bolt is inserted in the main body and key is removed, the sliding bolt will remain trapped in the main body. To release the sliding bolt key should be inserted in the lock. This will release the bolt & trap the key. Mechanical Interlock Type DL http://www.msenterprisingengineers.co.in/mechanical-interlock-type-dl.htm http://www.msenterprisingengineers.co.in/mechanical-interlock-type-dl.htm Sat, 07 Dec 2019 00:00:00 +0530 This is the basic unit of our interlocking system. These locks consist of a mechanism housed within a brass body. A shaft of round or square cross section is projected from the rear of Lock-body. The lock is operated by inserting and rotating a special key in the lock. Standard Lock with 90°, 65°, or 45°, clockwise or Anticlockwise rotation can be supplied.
