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.\u003c\/p\u003e\n\u003ch2 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSecurity \u0026amp;
