SW TOUCH LOCK LEFT AND RIGHT (BROWN & NERLING)

For uPVC sliding windows utilizing dark, wood-grain laminated profiles (like Walnut, Mahogany, or Dark Oak), a Brown finish is the industry standard to ensure the hardware blends seamlessly into the frame rather than standing out.

When pairing this color with a knurled (historically spelled “nerling”) design texture, it completely elevates the window hardware from standard commercial plastic to a luxury, tactile architectural detail.

Texture & Architectural Detailing

The Knurled Edge (Nerling): Rather than a smooth, slippery aluminum or plastic touch-lever, the handle features a distinct diamond-pattern or linear-cut textured grid. This pattern is cross-hatched directly into the zinc alloy or brass component prior to finishing.
Benefits: Beyond the high-end industrial aesthetic, the texturing adds significant slip-resistant grip. This makes operating heavy, double-glazed sliding sashes much easier on the fingers.
