FSB 1292 Door Lever Set • Casson

FSB 1292 is part of FSB's Standard Mortise Lock (SML) program — German-engineered architectural door hardware known for precise proportions and a tactile, ergonomic grip.

Developed in 2024 by Foster + Partners Industrial Design as a longer, slimmer evolution of the FSB 1291, drawn from the shapes of everyday tools and objects. It anchors FSB's largest product family, awarded the iF Design Award Gold in 2026.

Available in passage, privacy, single dummy, and double dummy configurations. Handing is required for single dummy.
