The Falcon 030733-000-55 is the OEM T Series Inner Spindle for Falcon T Series cylindrical locks, documented in the official Falcon T Series Parts Manual. The inner spindle is confirmed in the Chassis Assembly position across a broad range of T Series functions covering passage, privacy, closet, entry, office, classroom, dormitory, and storeroom functions. Per the SecurityParts.com product page, this product has a minimum order quantity of 5. Available (3-4 weeks).

What the T Series Inner Spindle Does

The inner spindle is the central internal shaft that runs through the Falcon T Series cylindrical lock chassis and connects the inside and outside lever hubs. When a lever is turned, the inner spindle transmits the rotational force to the latch retractor mechanism, retracting the latch bolt and allowing the door to open. On functions where the inside lever always operates freely, the inner spindle must transmit rotation from the inside lever at all times regardless of the outside lever state. When the inner spindle wears, deforms, or breaks, lever rotation may not transfer correctly to the retractor, causing the latch to fail to retract during lever operation. Replacing the 030733-000-55 restores correct mechanical engagement between the lever hub and the latch retractor on affected T Series functions.

Minimum Order Quantity of 5

Per the SecurityParts.com product page, the 030733-000-55 T Series Inner Spindle has a minimum order quantity of 5 units. Orders below this quantity cannot be placed for this part number. This makes the 030733-000-55 suitable for facilities or service providers that maintain inventory of common wear components across multiple Falcon T Series installations.
