The Schlage 03-042-RHO is the OEM Rhodes Rose for the Schlage ALX Series, ND Series, CO-100, CO-200, and CO-200/250 Series cylindrical locks, documented in the official Schlage ALX Series Service Manual (doc 113523), the Schlage ND Series Service Manual, and the Schlage CO Series Service Manual. Per the ALX Series Service Manual: "03-042 RHO inside/outside rose for all levers except Omega." The 03-042-RHO is the default rose included in every Schlage ALX chassis kit. 3-7/16 inch diameter. Finish must be specified. In stock.

The Default Rose in the Schlage ALX Chassis Kit

The Schlage ALX chassis kit (order code ALX CK) is a pre-assembled service package that includes a complete chassis assembly, an inside spring cage assembly, an ANSI strike assembly, and two roses. The ALX Series Service Manual confirms: "Each chassis kit includes one complete chassis assembly, one inside spring cage assembly, two roses (Rhodes design) and one ANSI strike assembly." The two roses included in every ALX chassis kit are the 03-042-RHO. This makes the Rhodes rose the standard and default inside/outside rose across the entire ALX and ND Series trim catalog.

The companion Omega rose (03-042-OME) is explicitly excluded from the chassis kit. The ALX Series Service Manual notes: "Omega rose design is not available with the chassis kit." When a project specifies the Omega lever, the 03-042-OME must be ordered separately. For every other lever design in the ALX and ND catalog, the 03-042-RHO is the correct rose and it comes included in the chassis kit when the chassis kit ordering path is used.

Schlage 03-042-RHO: Lever Design Compatibility

The 03-042-RHO serves nine standard lever design families across the ALX and ND Series plus their tactile variants. Standard designs: Athens (ATH), Boardwalk (BRK), Broadway (BRW), Latitude (LAT), Longitude (LON), Rhodes (RHO), Saturn (SAT), Sparta (SPA), and Tubular (TLR). Tactile variants: 8AT, 8BK, 8BY, 8LT, 8LN, 8RO, 8SP, and 8TR. Every one of these lever designs uses the 03-042-RHO on both the inside and outside trim positions. The Omega lever (OME) is the only design in the ALX and ND Series that uses a different rose, which is the 03-042-OME.

The Rhodes lever (RHO) that shares its name with this rose has an optional break-away feature available on most locking functions, as confirmed in the official Schlage ALX Series Data Sheet. When the break-away Rhodes lever is specified, the 03-042-RHO rose is the correct companion rose. Break-away levers are designed to fold down under forced lateral load rather than transferring attack force to the lock chassis, protecting the internal mechanism from permanent damage during vandalism attempts. The rose itself does not change when the break-away lever option is specified.

CO Series Compatibility: Beyond ALX and ND

The 03-042-RHO extends beyond the ALX and ND Series to cover the Schlage CO Series electronic access control cylindrical locks, specifically CO-100, CO-200, and CO-200/250 configurations. The CO Series combines electronic credential reading capability (proximity, smart card, keypad, or mobile) with the same trim format as the mechanical ND Series. Because the CO Series uses the same 03-042 rose mounting format, the 03-042-RHO serves as the inside/outside rose for CO Series installations using any lever design from the compatible list.

The 03-042-OME (Omega rose) was documented only in the ALX and ND Series Service Manuals. The 03-042-RHO is documented in three: ALX, ND, and CO Series Service Manuals. This broader documentation coverage reflects the 03-042-RHO status as the default rose across all three product lines.
