Introducing the new Aluco DUPLEX LOCK, an innovative feature that takes the authenticity of Aluco steel-look (aluminium) windows to an entirely new level. Designed to replicate the visible top-and-bottom locking system found on traditional steel windows, the Duplex Lock combines heritage-inspired styling with modern security and performance.

Using a single handle to operate two locking points, it delivers elegant functionality while enhancing the distinctive steel-look aesthetic that makes our Aluco windows so desirable.

Available in a range of period-inspired finishes including Antique Brass and Bronze, the Duplex Lock is more than just window hardware. It's a carefully engineered design feature that perfectly captures the character of classic steel windows without the cost, maintenance or limitations of steel.

For homeowners, architects and renovators seeking the most authentic steel-look window available, it's another reason why Aluco continues to set the benchmark.
