The Schlage 03-277-RHO is the OEM Rhodes Lever designed for Sargent Full-Size Interchangeable Core (FSIC / J-SAR) 6-pin applications, for the Schlage AD Series, CO Series, ALX Series, and ND Series cylindrical locks, documented in four official Schlage Service Manuals: ALX, ND, AD, and CO Series. Per the SecurityParts.com product page: "Schlage 03-277-RHO is a genuine OEM Rhodes-style exterior lever less core for compatible Schlage commercial locks configured for Sargent Full-Size Interchangeable Core (FSIC) cylinders. Supplied less core for field installation of the compatible Sargent LFIC." Standard non-tactile Rhodes lever. Non-handed.

Three Legacy Part Numbers Replaced by the 03-277-RHO

The 03-277-RHO replaces three legacy part numbers, as confirmed on the SecurityParts.com product page under "Original Part#."

• 03-077-RHO: Original part number for cylindrical lock outside trim applications using the Rhodes Sargent FSIC lever.
• 09-377-RHO: Original part number for mortise lock trim applications. The 09 prefix in the legacy Schlage system identified mortise trim levers.
• 03-377-RHO: Original part number for exit device outside trim applications.

Any maintenance record or specification referencing these three legacy numbers maps to the 03-277-RHO as the current OEM replacement, regardless of whether the original installation was on a cylindrical lock, mortise lock, or exit device.

Standard vs Tactile: 03-277-RHO vs 03-277-8RO

The 03-277-RHO is the standard non-tactile Rhodes Sargent FSIC lever. The 03-277-8RO is the tactile version with knurled tactile grooves on the handle for ADA hazardous area identification. Both accept a Sargent FSIC (J-SAR) 6-pin core and supply less cylinder. Confirm the original installation specification before ordering to avoid installing a standard lever at a position that required the tactile designation.

03-277-RHO vs 03-277-ATH: Service Manual Coverage Difference

The 03-277-RHO and the 03-277-ATH (Athens Lever, Sargent FSIC Less Core) are both standard non-tactile levers in the 03-277 Sargent FSIC format, at the same price with three legacy part numbers each. A notable difference is the Service Manual documentation. The 03-277-RHO is documented in four Service Manuals: ALX, ND, AD, and CO. The 03-277-ATH is documented in two Service Manuals: ALX and ND only. When AD Series or CO Series documented coverage is required alongside the standard non-tactile designation in a Sargent FSIC installation, the 03-277-RHO has broader formal Service Manual coverage than the 03-277-ATH. The lever profile is the only aesthetic difference between the two.

Series Compatibility and Finishes

Per the SecurityParts.com product page: "This replacement lever restores the original appearance and functionality of compatible AD Series, CO Series, ALX Series, and ND Series locks configured for Sargent large format interchangeable cores." The primary function is "Accommodates a Sargent conventional 6-pin LFIC (J-SAR) interchangeable core for manual latch retraction and rapid re-keying safety." A compatible Sargent FSIC core must be sourced separately. Finish must be specified at time of order. Contact SecurityParts.com for current finish and availability information.
