FSB 1291 Door Lever Set

FSB 1291 is part of FSB's Standard Mortise Lock (SML) program — German-engineered architectural door hardware known for precise proportions and a tactile, ergonomic grip.

Foster + Partners Industrial Design drew FSB 1291 along a single freehand curve, with a short grip and soft geometry the designers describe as a play of light. It opens FSB's largest product family, which took the iF Design Award Gold in 2026.

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