DormaKaba L1000 Series Clutch Assembly – Right Hand (Part 201788-000-01)

The DormaKaba 201788-000-01 is a genuine Right Hand Clutch Assembly for the L1000 Series lever-operated access control lock — the platform originally introduced as the Simplex Unican mechanical combination lock and carried forward under the Simplex, Simplex Unican, Kaba, and now DormaKaba brand names over more than 30 years of continuous production. Field technicians and contractors sometimes refer to this platform as a cypher lock or combination push-button lock. This clutch assembly is the correct service part when the lever mechanism exhibits slippage, free-spinning, or fails to retract the latch under normal operation.

Handing Information

A Right Hand (RH) Clutch Assembly is compatible with both Right Hand (RH) swing and Right Hand Reverse (RHR) swing doors. Verify door handing before ordering — the clutch assembly is handed and is not field-reversible.

• Right Hand (RH): Hinges on the left when viewed from the pull (exterior/secure) side; door swings away from you into the space.
• Right Hand Reverse (RHR): Hinges on the left when viewed from the push (interior) side; door swings toward you.

Key Benefits

• Genuine OEM-sourced replacement part — maintains original lock performance and code compliance
• Correct fit for the long-running L1000 lever platform across all brand-name iterations (Simplex, Kaba, DormaKaba)
• Restores positive lever-to-latch engagement without full lock replacement
• Handed design ensures precise mechanical indexing for reliable, cycle-rated operation

Typical Applications

• Preventive maintenance and repair of DormaKaba / Kaba / Simplex L1000 Series lever combination locks in commercial, institutional, and government facilities
• Schools, healthcare facilities, and office buildings where L1000-platform locks have been in service for extended periods
• Service calls where the lever spins freely or fails to retract the latch bolt despite correct combination entry
