Salsbury Maximum Height Recessed Mounted 4C Horizontal Parcel Locker | 3 Parcel Lockers with USPS Access - Rear Loading

The Salsbury 3716S-3PARU is a USPS-approved, recessed-mounted 4C stand-alone parcel locker unit manufactured to USPS-STD-4C specifications for apartments, commercial buildings, and residential developments requiring dedicated or supplemental package receiving capacity in a narrow, full-height wall-recessed installation with rear carrier access. Configured as a single-column, maximum-height unit at 57⅛" tall, it houses 3 parcel lockers in a graduated size arrangement, 1 PL4.5 (15½" H), 1 PL5 (17¼" H), and 1 PL6 (20¾" H) providing a range of package accommodation sizes within a compact single-column footprint suited to installations where column width is constrained. Packages are loaded from behind through a heavy-duty rear access door with latch and continuous hinges, making it well suited to pass-through wall or back-of-house delivery configurations. Each locker is fitted with a 2-key security system, and the included 4C connector kit allows direct integration alongside existing or new 4C mailbox banks.
