The Falcon 030733-002 is the OEM Inner Spindle for the Falcon T851 and T881 electrified storeroom cylindrical locks, documented in the official Falcon T Series Parts Manual. Per the SecurityParts.com product name, this inner spindle is specifically designated for the T851/881 functions. Available (3-4 weeks).

Electrified Inner Spindle for T851 and T881 Functions

The T851 and T881 are electrified storeroom lock functions in the Falcon T Series. The T851 is the fail safe version, which unlocks when electrical power is removed. The T881 is the fail secure version, which remains locked when electrical power is removed. Both functions incorporate internal electrical components within the lock chassis that allow the latch retractor to be controlled by an access control or alarm system signal in addition to mechanical key operation.

The 030733-002 inner spindle is designed for use in these electrified chassis configurations. The significantly higher price of this spindle compared to the standard T Series inner spindle (030733-000-55) reflects the specialized construction required to accommodate the electrified internal mechanism of the T851 and T881 functions. When the inner spindle in an electrified storeroom lock fails, it must be replaced with the correct electrified spindle part rather than a standard spindle, which would not interface correctly with the electrified chassis components.

Distinguishing the Correct Inner Spindle for T851 and T881

The Falcon T Series catalog includes several inner spindle part numbers, each designed for specific function groups. The 030733-000-55 standard inner spindle covers passage through storeroom functions but is not listed for T851 or T881. The 030733-002 is the correct inner spindle specifically for the T851 and T881 electrified storeroom functions. Using the standard spindle in an electrified function, or the electrified spindle in a standard function, will result in incorrect mechanical or electrical engagement. Confirm the exact function before ordering.
