Handed Orientation: They come in a mirrored pair engineered for specific sides of a window frame—the Left handle curves gently outward to the left, while the Right handle mirrors it to the right.
Mechanism: The top pivoting lever operates the locking latch or wedges into a strike plate mounted on the window frame to seal it shut securely.
Application: These heavy-duty brass or polished steel handles are a standard hardware fixture for classic steel and French casement window setups.
