4C Units can be used together with new Vario Configurable Mail Shelters. Vario mail Shelters are constructed such that 4C Units from 4C suites A, C, D, and G can be used in the Vario units.  4C units from different 4C suites, cannot be mixed with each other within the same Vario Shelter unit.  4C units from different suites, however, can be mixed by placement in separate Vario Shelters.  Units in all suites are either single-wide - 17 1/2", or double wide 31 9/16".   All 4C units within the same suite are all the same height.  7 different heights available.

Postal regulation STD-4C requires 1 parcel locker for each 10 customer compartments.   4C Units come prepared for the USPS to install special USPS locks for the master door, parcel lockers, and outgoing mail compartment. 

Applications:
