The union (ex chubb) 3G114E bs 3621:2007 has proved to be one of the most popular locking solutions in the UK over the last 30 years. The chubb 3g114 E features an extended bolt and conforms with British Standard 3621. The union 5 lever mortice deadlock is commonly found in timber doors as the “secure element” in conjunction with a Latch or Nightlatch. The union 3g114e deadlock has larger “keep” and additional anti drill plates on each face of the lock – making replacement of an original 3G114E a job for a skilled tradesman.

The 3G114E is available in other variations:
