Per the SecurityParts.com product page: "Houses Sargent 6-pin FSIC cores for manual latch retraction and tactile ADA alerts." The lever features knurled tactile grooves on the back of the handle. Supplied less cylinder. Non-handed. Original Part# 03-077-8TH. Available (3-4 weeks).

What the 03-277 Sargent FSIC Format Means

The 03-277 prefix identifies levers with factory preparation for the Sargent Full-Size Interchangeable Core (FSIC) in the J-SAR format. Per the SecurityParts.com FAQ: "This lever will not accept standard Key-in-Lever cylinders or Schlage-branded interchangeable cores. It is uniquely machined to seat the specific physical sizing and locking lug paths of a Sargent FSIC system." A compatible Sargent FSIC (J-SAR) 6-pin core must be sourced separately. The core is not included.

The 03-277 format is distinct from the 03-244 Sargent conventional KIL lever family. The 03-244 levers accept a Sargent conventional Key-in-Lever cylinder, which is a non-interchangeable cylinder pinned at the factory. The 03-277 levers accept a Sargent FSIC, which is a full-size interchangeable core that can be removed and replaced in the field using a control key. Confirm the cylinder type in the installed lock before ordering to ensure the correct format is selected.

Knurled Tactile Grooves and ADA Compliance

Per the SecurityParts.com product page, the 03-277-8AT "features knurled tactile grooves on the back of the handle to meet ADA compliance for hazardous or restricted areas." The tactile grooves provide detectable surface feedback for persons with visual impairments at outside trim positions where the Sargent FSIC core requirement and the tactile designation are both specified. The primary function is confirmed as "Houses Sargent 6-pin FSIC cores for manual latch retraction and tactile ADA alerts."
