The Falcon 031467-004-30 is the OEM Schlage FSIC Throw Member for the Falcon T Series IC cylindrical lock, designated for the RU/T571 dormitory function configuration, documented in the Falcon T Series Parts Manual. It is compatible across 12 T Series IC function variants: T351-IC, T381, T381-IC, T411, T501-IC, T511-IC, T521-IC, T561-IC, T571-IC, T581-IC, T851-IC, and T881-IC.

The throw member is specific to the Schlage FSIC (Full Size Interchangeable Core) format. It is not compatible with Best/Arrow SFIC cores or other IC formats. Confirm the installed IC format before ordering.

What the FSIC Throw Member Does in a Falcon T Series Lock

In an FSIC lock, the system has two physically separate components where a standard lock has one. A standard lock has a fixed cylinder - the cylinder housing and the plug are both permanent. An FSIC lock has a removable core (the plug) that can be extracted with a control key, plus a housing that stays in the lock permanently. The throw member lives inside that permanent housing.

Here's what the throw member actually does: when an FSIC core is inserted into the Falcon T Series lock, the tail of the core engages the throw member. When the key is turned, the core rotates, and that rotation drives the throw member. The throw member is the mechanical interface that converts core rotation into the locking action of the lock chassis - locking or unlocking the outside lever, retaining or releasing the hub, depending on the specific T Series function installed.

When a control key removes the core, the throw member stays behind in the housing. It holds its last-commanded position until a replacement or rekeyed core is inserted. This is a key operational detail: if the throw member fails or wears out, the core may rotate in the housing without producing the correct locking/unlocking response in the lock chassis. Replacing the 031467-004-30 throw member restores the mechanical connection between the FSIC core and the lock mechanism.

Falcon FSIC Throw Member: 031467-004-30 vs 031467-000-30

The Falcon T Series FSIC throw member family has at least two part numbers:

031467-000-30 = "RU/T Series Standard Functions" - covers the standard function group within the T Series IC catalog.

031467-004-30 (this product) = "RU/T571" - designated for the T571 dormitory exit function and the extended compatible function list shown above.

The suffix difference (-000 vs -004) indicates these are physically different components with different throw travel, cam interface geometry, or hub engagement profiles to match the different mechanical behavior of each function group. The T571 dormitory function has specific operational behavior - the inside push button locks the outside lever in a way that differs from standard entry functions - and the throw member geometry is matched to that function's mechanical requirements.

Do not substitute 031467-000-30 for 031467-004-30 in the functions listed above, or vice versa. The throw member geometry must match the function's chassis behavior.

Falcon Cylindrical Lock Catalog: T Series IC Function Applications

The compatible functions for the 031467-004-30 span the full range of keyed T Series functions used in commercial IC installations. The T501 is the entry function, T511 is entry/office, T521 is office, T561 is classroom, T571 is dormitory/exit, T581 is storeroom. The T851 and T881 are the electrified storeroom functions in fail-safe and fail-secure configurations respectively. All use the same Schlage FSIC throw member format and all are served by the 031467-004-30 in this specific throw member configuration.
