Redesigned Parcel Lock Now Available

The redesigned parcel lock for parcel lockers of older (revision E) cluster box units (CBUs) is now available. The redesigned lock includes the following features:

• Properly positioned upper lock (the pins face down). This will prevent buildup of dust and dirt, which affected the tumblers of the previous locks.
• Tool clearance hole located in the lock’s rear cover. If a key breaks in the lock, you will no longer have to drill out the two rear cover rivets in order to remove the rear cover and push out the key stubs. The access hole in the rear cover is aligned with the back of the upper (customer) lock, making it easy to push out a broken key stub. The field maintenance pro­cess is now easier and quicker.
• A tab-in-slot design in place of the lower rear cover rivet. The rear cover can now be held in place with only one rivet, which is easily accessible from the top of the lock assembly. It is now easier to replace the lock cover, saving time and effort.
• Repositioned upper (customer) lock key code mark­ing location. This makes it easier to identify the key code needed to order replacement keys.
