The Falcon Q330-433 LAT is the OEM Latitude lever assembly for the Falcon T Series Grade 1 cylindrical lock, configured for Schlage Full Size Interchangeable Core (FSIC). It is the field replacement lever trim for T Series locks that were specified or are being converted to the Latitude lever style in the Schlage FSIC cylinder format. Finish must be specified at time of order. This part is documented in the Falcon T Series Parts Manual and ships as a lever assembly ready for installation on an existing T Series lock chassis or as part of a new assembled specification.

The Latitude (LAT) is one of seven lever styles available across the Falcon T Series catalog. It carries the same Grade 1 structural rating and the same compression spring chassis as every other T Series lever configuration.

Falcon LAT Lever: What the Latitude Style Is

The Latitude is a horizontal, architectural lever profile - clean lines, a moderately elongated bar with a low-profile return, and a design that suits contemporary commercial interiors without the bulk of a more traditional lever shape. Like all Falcon T Series levers, it is solid pressure cast zinc finished to match companion hardware. The rose mounts through-bolted using steel rose inserts in a wrought brass or bronze housing, giving the trim assembly the rigidity to pass ANSI/BHMA A156.2 Series 4000 Grade 1 cycle testing.

The Latitude lever is available with abrasive coating along the lever length for applications requiring hazardous area identification per ADA accessibility standards, and with lead lining for X-ray room and radiation-sensitive area installations. Both are options across all T Series lever styles, including the LAT.

Falcon Cylindrical Lock FSIC Configuration: Schlage Format Explained

The T Series is specifically engineered to accept multiple cylinder formats, which is one of its defining commercial advantages over competing Grade 1 cylindrical locks. The Q330-433 LAT is the FSIC Schlage format lever - the lever housing is configured for Schlage Full Size Interchangeable Core cylinders.

FSIC cylinders are larger removable cores that can be pulled out of the lock with a control key without removing the lock from the door or disassembling the trim. The control key engages the control pin at 15 degrees of rotation, allowing the core to be extracted. A replacement or rekeyed core drops back in and latches automatically. This makes FSIC the standard specification for large commercial campuses - universities, healthcare systems, government buildings - where frequent rekeying across hundreds of doors is a practical reality.

Schlage FSIC format is distinct from the SFIC (Small Format Interchangeable Core) format used by Best, Arrow, and ASSA. The two formats are not interchangeable. If the installed T Series lock uses Schlage FSIC cores, the Q330-433 LAT is the correct lever. If it uses Best/Arrow/ASSA SFIC cores, a different lever assembly applies. Confirm the IC format before ordering.

Falcon Cylindrical Lock Catalog: T Series Lever Assembly Replacement

The T Series lever assemblies are independently replaceable without replacing the lock chassis. The compression spring mechanism, the chassis hub, and the internal mechanism all remain on the door. The lever trim pulls off and a replacement lever assembly installs onto the existing hub. This is a design feature Falcon built into the T Series specifically for high-traffic institutional applications where lever damage from abuse, vandalism, or wear is a maintenance reality.

The Q330-433 LAT is the correct replacement when the Latitude lever on a Schlage FSIC configured T Series lock is damaged, worn, or being replaced during a renovation that changes lever style across a building. Specify finish when ordering to match the existing installation.
