Schlage 03-031 Lever, Cylinder Prep, ND Series (Before February 2017)

The 03-031 is the key-in-lever trim for Schlage ALX, CO, and ND Series locksets, so it drops onto an ND lock body directly. One caveat on vintage: this version is the pre-February 2017 lever. Schlage changed the ND lever interface at that point, so match your lock's build era before ordering.

No cylinder is included. The 03-031 ships less cylinder with the key-in-lever prep machined, so you reuse the cylinder out of the lever you are replacing or order one separately keyed to your system. That is the point of the part for a locksmith rebuilding a keyed lever: the trim is new, the keying stays yours.

Handing doesn't apply. The 03-031 is non-handed, so a single part number covers both left and right hand doors. Useful if you stock spares across a building and don't want two bins of the same lever.

Yes, the 03-031 lever is ADA accessibility compliant, and it also meets the California code requiring a return to the door of 1/2 inch or less. That matters on any lever specified for a public-facing or state-funded opening in California, where a lever end that stands off further than 1/2 inch is a clothing snag hazard and gets rejected on inspection.

That is exactly what the 03-031 is for. It's a replacement trim part, lever only, not a complete lock. If the chassis, latch, and strike are still good and you have a broken, worn, or mismatched lever, you buy this and keep the lock in the door. If the chassis itself is failing, replace the lockset instead.

No - those are two different classes of part. The Schlage 03-031 is lock trim: a lever only, supplied less cylinder and prepped to take a key-in-lever cylinder, non-handed, for ALX, CO and ND Series locksets. The Cal-Royal CALDOR238 CAL101 is a dormitory dead latch, a complete latching unit in the dormitory function. Swapping the 03-031 onto a door gives you the handle and cylinder prep, not the latching mechanism, so it is a trim replacement on an existing Schlage chassis rather than an alternative to a dormitory dead latch.

Overall length is 5-1/8 inches. Measure from the rose out to the lever tip when you check clearance against an adjacent wall, door stop, or a second leaf on a pair. On the return side, the lever comes back to within 1/2 inch of the door face, so it sits tight rather than standing proud.

Nine lever designs: Athens (ATH), Boardwalk (BRK), Broadway (BRW), Latitude (LAT), Longitude (LON), Omega (OME), Rhodes (RHO), Sparta (SPA), and Tubular (TLR). Ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial, and 643E aged bronze. Match the design and finish code off the lever already on your other doors and the replacement disappears into the run.

Yes. The 03-031 is offered in 626AM, satin chrome antimicrobial, alongside standard 626 satin chrome. For a facility standardizing high-touch hardware in patient corridors, clinics, or classrooms, that lets you swap trim to the antimicrobial finish without touching the lock chassis or the keying.

The 03-031 is mechanical trim, not electronic. It does fit the CO Series, which is Schlage's offline electronic lock line, as the mechanical key-in-lever trim on that lock, along with ALX and ND. It is not itself a powered or credential-reading part, so it won't add access control to an opening that doesn't already have it.

If you're replacing a whole lock, yes, this is the wrong item. The 03-031 is lever trim only, with no chassis, no latch, and no cylinder. Buy a complete lockset instead and pick the function you need. For a dormitory function deadlatch, for example, the Cal-Royal CALDOR238 CAL101 is a complete unit rather than trim.

Pressure cast zinc, plated to match the product finish specification. Because the plating is done to the BHMA finish code, a 626 lever ordered here matches the 626 hardware already on the opening. Order by the number, not by the description, and the match holds.

Commercial. The 03-031 is trim for the ND and ALX commercial lock lines, which are the cylindrical locks specified in schools, offices, and multi-family corridors. It is not a residential-grade lever pack from a big box shelf, and it will not fit a residential tubular lockset.
