The KS31.2 CL ES supports a wide range of sliding configurations with its 24/28 mm interlock depth, delivering enhanced panel-to-panel sealing and structural rigidity across multi-panel installations of up to 6 sashes.

The add-on frame system enables seamless multi-sash expansion, while the choice between stainless steel and aluminium guiderails allows specification teams to balance durability, aesthetics, and budget requirements for each unique project.

An optional flyscreen provision and a concealed striker detail ensure the system maintains clean, uninterrupted sightlines, combining sophisticated visual refinement with elevated security performance across all configurations.

CRAFTED FOR PERFORMANCE 

System Features

The KS31.2 CL ES is a modular frame sliding system engineered around a 24/28 mm interlock for superior weather performance and panel alignment. It accommodates a maximum panel size of window: 1.0 m (w) × 1.8 m (h) and door: 1.2 m (w) x 2.4 m (h) and accepts glass thickness from 5 to 22 mm.

With a wind load capacity of up to 2 kPa, a choice of stainless steel or aluminium guiderail provisions, and a concealed striker for a refined finish, the system is equally at home in high-specification residential and commercial environments.

Single and multiple locking mechanisms deliver robust security, while the modular add-on frame and optional flyscreen provision ensure the KS31.2 CL ES remains a complete, adaptable sliding solution from design through to installation.
