Schlage 09-633N Inside Thumbturn x Lever N Escutcheon

That is exactly what this part is for. If the lock case still works and only the inside trim is dented, scratched, or the wrong finish, the 09-633N swaps the inside thumbturn-and-lever plate and leaves the mortise case in the door. Common on rental turns and building refinishes where the door prep stays as it is.

Yes. The 09-633N covers the plate. The lever, the thumbturn, and the mortise lock case are ordered on their own, and all of them need to be Schlage L Series parts to line up with this trim. Match the finish across the lever and turn as well, since the plate ships in one of nine finishes and a mismatch on the same door is obvious.

Nine finishes: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, 625 bright chrome, 626 satin chrome, and 630 satin stainless steel. If you are matching escutcheons across a building, order by the BHMA number rather than the finish name, since 626 satin chrome and 630 satin stainless read similarly in photos but are different materials and will not match side by side.

It comes down to what your door is already prepped for. An escutcheon like the 09-633N is a single 8 inch plate covering the lever hub and the thumbturn together, which hides an older or rougher door prep and gives a continuous piece of trim. Rose trim uses separate small round escutcheons for the lever and the turn and shows more of the door face. If you are retrofitting a door that previously carried plate trim, stay with the escutcheon; cutting back to roses can leave the old prep exposed.

The N escutcheon is a symmetrical rectangular plate with a lever hub and a thumbturn hole, so the plate itself is not handed. Handing lives in the mortise lock case and the lever, not this trim. Order the lever and the L Series case to your door's hand.

For corridor and entry doors that get handled constantly, 630 satin stainless steel and 626 satin chrome hide wear and fingerprints better than the polished options. 605 bright brass and 625 bright chrome show scratches and hand oils quickly, which is why they read better on low traffic or decorative openings. 613 oil rubbed bronze and 622 matte black are living or coated finishes that change appearance with wear, so keep them consistent across a whole floor rather than mixing them into an existing satin chrome fleet.
