Schlage Commercial ALX Series 2-3/8" Backset Restoring Spring Latch With 1" x 2-1/4" Square Corner Faceplate

Both. The A Series latch is adjustable for flat or beveled edge doors, so you set it to match the door you are working on rather than ordering a different part number. That matters on commercial openings where the lock stile is beveled to clear the frame.

It is a restoring spring latch, not a deadlatch. There is no auxiliary deadlocking plunger riding alongside the latchbolt, so it does not resist a credit card or shim attack the way a deadlatch does. Use it on passage, privacy, and interior openings where the latch just needs to hold the door closed and return positively. If the opening is an exterior or entry door where you want deadlocking, look at a deadlatch instead, such as the Dexter Grade 1 deadlatch for the C1000 Series.

Yes. The latch is a certified Schlage part for the ALX Series and is made to work with the lock trim, so you can pull the old latch and drop this one in behind the levers you already have. That is the normal repair: the trim is fine, the latch has worn or stopped restoring, and you replace only the latch.

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 643E aged bronze. Match the number to the finish code stamped or specified on the lock you are repairing, and the faceplate on the door edge will match the rest of the trim. 626 satin chrome and 613 oil rubbed bronze are the two most common on commercial ALX openings.

It is a commercial-rated part built with stainless steel, which is what you want on an opening that cycles all day: stainless resists the wear and corrosion that chews up a plated latch in a corridor, restroom, or exterior-adjacent door. This is the commercial ALX line, not a residential latch.

That is the failure this part addresses. A restoring spring latch returns the latchbolt and the lever to their rest position under spring force; when the spring weakens, the lever droops and the bolt drags on the strike instead of snapping home. Replacing the latch behind the trim usually clears it, and on ALX openings the trim itself stays on the door.

Not always. Deltana splits its 2-3/8 inch backset latches by function: the G1RLE238 is the Grade 1 regular latch for entry, and the G1RLP238 is the Grade 1 regular latch for passage/privacy. The Schlage ALX Series 2-3/8 inch spring latch is a restoring spring latch supplied as a replacement part for Schlage lock trim, so the function is set by the ALX lockset it goes into rather than by the latch being ordered separately. Match the latch to the lock body you are servicing.

On the Deltana regular latches, Grade 1 is stated across the range: G1RLE238 and G1RLE275 in entry, G1RLP238 and G1RLP275 in passage/privacy. The Schlage part is a certified Schlage replacement latch for the commercial ALX Series, and in a commercial ALX lockset the grade is carried by the complete lockset rather than the latch ordered on its own. If the drawing calls out a graded latch as a standalone line item, the Deltana regular latches state it directly.

The Lockey M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset, and it fits doors 1-1/8 inch to 2 inch thick. It is a complete lock with its own credential method, not a latch that drops into existing trim. The Schlage ALX Series part is the latch alone, a stainless steel replacement that adjusts for flat or beveled edge doors and works with Schlage lock trim already hung in the opening.

No. It is a lock-trim latch for a bored ALX opening and nothing else. For a sidelite you want a purpose-built auxiliary latch like the Accentra YSSL10 security sidelite latch, which is fire rated and made for 1-3/4 inch doors. For a keyless combination opening, the Lockey M230 is a self-contained mechanical pushbutton deadlocking spring latch lock with an adjustable backset, fitting doors 1-1/8 to 2 inches thick. Neither of those is a drop-in for an ALX latch pocket, and this latch is not a drop-in for theirs.
