Keyless Two-Way Locking
In pharmaceutical cleanrooms, hospital air-locks, and laboratory containment areas, personnel require rapid deadbolt locking from both sides without carrying contaminated physical keys.
Dual-Turnpiece Architecture
- Thumbturns on Both Faces: Both interior and exterior sides feature solid brass thumbturn knobs.
- Direct Drive: Rotating either turnpiece throws or retracts the deadbolt immediately.
- Sizing Flexibility: Available in symmetrical and asymmetrical lengths up to 120 mm.
