Awning & Casement Locks

Awning and casement locks are essential pieces of window hardware designed to keep homes, apartments, and businesses safe. Unlike standard sash or sliding locks, these locks secure outward-opening windows, giving you both peace of mind and ventilation flexibility. Doric’s range of locks combines strength, ease of use, and compliance with Australian Standards — making them a trusted choice for builders, locksmiths, and property managers across the country.

Whether you need keyed awning locks, casement window lock systems, or replacement awning window locks, the right solution ensures both day-to-day convenience and long-term security.

Types of Awning & Casement Locks

Different windows call for different lock designs. Doric supplies a wide range of window locks for awning windows and casement systems so you can match hardware to the specific opening style.

Keyed Awning Locks

These are the most common option for external awning windows. A keyed mechanism provides strong security while still allowing controlled ventilation. Many models feature dual-function systems where you can partially open the window without compromising safety.

Casement Window Lock Systems

Casement windows open outwards like a door, which means they need lock systems that resist forced entry at the hinge side. Doric’s casement window lock hardware ensures the sash is held tight against the frame, preventing prying or rattling in high winds.

Replacement Awning Window Locks

Over time, locks can wear down due to heavy use or weather exposure. Replacement units are designed to line up with existing cut-outs, making it easy to upgrade without drilling new holes or replacing the window frame.

Specialty Window Fasteners

For strata or multi-storey properties, restrictors and tamper-resistant locks provide compliance with child safety requirements while still allowing airflow.
