Sliding Window Locks

Sliding window locks are a vital safeguard for homes, strata properties, and commercial sites. By securing sliding sashes in place, they protect against forced entry, prevent accidental openings, and improve compliance with Australian safety standards. A reliable lock not only provides peace of mind but also ensures windows operate smoothly and last longer.

Doric offers a complete range of keyed sliding window locks, child safety restrictors, and durable lock systems for aluminium and timber frames. Whether you’re upgrading security for a family home, managing maintenance across a strata complex, or fitting out a new commercial project, Doric sliding window locks are designed to perform in Australian conditions.
