## Abstract

Disclosed herein is a fenestration assembly. The assembly includes a movable sash assembly, a first lock counterpart connected to the movable sash assembly, a fixed sash assembly, a second lock counterpart connected to the fixed sash assembly, and a sill configuration. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a first height, the movable sash assembly is lockable to the fixed sash assembly. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a second height, the movable sash assembly is lockable to the fixed sash assembly. While there is an absence of locking between the movable and fixed sash assemblies, the movable sash assembly is movable relative to the sill configuration.
