A sally in jail refers to a sally port—a secure, controlled access point used for bringing individuals into or out of a correctional facility. It functions like an airlock, ensuring that movement is monitored and secure at all times.

How a sally port works

The sally port consists of multiple heavy-duty doors that do not open simultaneously. When a police or transport vehicle enters, the outer door closes completely before the inner door opens. This creates a buffer zone that prevents unauthorized exits and enhances safety for staff and inmates.

Origin of the term

The term 'sally port' has military roots, originally describing a passage in fortifications that allowed soldiers to sally forth for attacks while remaining protected. In modern jails, the function is defensive—focused on containment and control rather than offense. Today, it is a standard feature in secure facilities, critical for managing inmate transfers safely.
