Schlage 11-111 - A Series Spring Latch, Square Corner, 1" x 2-1/4" Faceplate, 2-3/4" Backset

Both. The A Series latches adjust for flat or beveled edge doors, so one part covers a square-edge door and a beveled stile without ordering a different latch. That is useful in a building where the doors were not all hung the same way.

Square corner faceplate, 1 x 2-1/4 inches. If the edge mortise on your door is a square-cut pocket at that size, the latch drops straight in with no re-routing. Doors prepped with a radius-corner faceplate pocket will show a gap at the corners, so match the corner style as well as the dimensions.

Yes, the 11-111 is a Schlage A Series replacement latch and is made to work with the lock trim already on the door. Keep the knobs, rose and strike and swap only the latch when the bolt is sticking or the spring has gone soft.

No. On an A Series knob lock the latch is a separate part, and the 11-111 is the factory replacement for the square corner, 1 x 2-1/4 inch faceplate, 2-3/4 inch backset version. Pull the trim, back out the latch screws, drop the new one in and reuse the knobs and strike. Confirm your faceplate size and backset first, because A Series latches are also built in other faceplate and backset combinations.

The Schlage 11-111 is a 2-3/4 inch backset spring latch with a square corner 1 inch by 2-1/4 inch faceplate, so it will not reach a 2-3/8 inch bore. For that opening, the Deltana G1RLE238 is a Grade 1 regular latch in entry function at 2-3/8 inch backset, and the Deltana G1RLP238 is the Grade 1 regular latch in passage/privacy function at the same 2-3/8 inch backset. Measure from the door edge to the center of the bore to confirm which backset the door is prepped for before ordering.

Yes. The Deltana G1RLE275 is a Grade 1 regular latch in entry function at 2-3/4 inch backset, and the Deltana G1RLP275 is the Grade 1 regular latch in passage/privacy function at 2-3/4 inch backset. Both share the 2-3/4 inch backset of the Schlage 11-111. The difference is that the Schlage 11-111 is a certified Schlage replacement part for A Series lock trim, so if the trim on the door is Schlage A Series, the 11-111 is the part built to it; the Deltana latches are chosen by function and grade rather than by matching a Schlage chassis.

No. The Dexter Grade 1 Deadlatch for C1000 Series is built for the Dexter C1000 chassis, and the Schlage 11-111 is a certified Schlage A Series part made to work with A Series lock trim. They are not interchangeable across chassis. It is also a deadlatch rather than a spring latch, so it carries a deadlocking plunger the 11-111 does not. Match the latch to the lock family already in the door.

The Schlage 11-111 is an A Series spring latch for commercial lock trim, sold as a certified Schlage replacement part. For a sidelite opening specifically, the Accentra YSSL10 is a security sidelite auxiliary latch with an ADA compliant thumbturn, fire rated, for 1-3/4 inch doors. It is an auxiliary latch for the sidelite panel rather than a latch that drops into a bored A Series lock, so the two serve different openings in the same entrance.

It is a spring latch, meaning the bolt is beveled and retracts when the door closes against the strike. It does not carry a deadlocking plunger. For an exterior opening where you want the latch guarded against being carded, specify a deadlatch instead of this one.

It is a commercial-duty part built in stainless steel, which is what you want for a corridor or tenant door that cycles all day. Stainless also holds up better than plated steel in a damp stair or a coastal exterior opening.

Eight finishes: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome and 643E aged bronze. Only the faceplate shows once the door is hung, and it shows on the edge, so match it to the existing faceplate and strike rather than to the knob if the two ever differed. For a fleet of doors in a property, 626 satin chrome and 613 oil rubbed bronze are the common commercial choices.

The 11-111 is fixed at 2-3/4 inches, so it will not cover a mixed set of preps. Deltana's regular latches are ordered per backset, G1RLE238 or G1RLP238 for 2-3/8 and G1RLE275 or G1RLP275 for 2-3/4, so you would stock both. If you are replacing the whole lock rather than a latch, the Lockey M230 keyless deadlocking spring latch lock has an adjustable backset. Easiest route on a property with mixed doors is to measure a few, count how many fall each way, and buy to those two counts.

Only where the preps match. The 11-111 covers doors with a 2-3/4 inch backset and a square corner 1 x 2-1/4 inch faceplate pocket. Survey a sample of your openings for those two things; if the building was hardware-specified in one package, they will usually all be the same, and one part number then covers every door. Older or renovated wings often carry a 2-3/8 inch backset or a radius faceplate and need a different A Series latch.

The Schlage 11-111 is a replacement spring latch that works behind A Series lock trim, so it needs an existing lock chassis and trim to operate it. If the opening is being converted to keyless access, the Lockey M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset and a 1-1/8 inch to 2 inch door thickness range, so it brings its own credential and latch rather than replacing a component inside a Schlage lock.

It depends on what is already hanging. Where the doors carry Schlage A Series trim, the Schlage 11-111 is the certified Schlage part for them, in a square corner 1 inch by 2-1/4 inch faceplate at 2-3/4 inch backset, adjustable for flat or beveled edge doors, in stainless steel, and offered in finishes including 626 satin chrome and 613 oil rubbed bronze so it can be matched to existing trim. Where the standard is being set by function instead, the Deltana G1RLE275 covers entry and the Deltana G1RLP275 covers passage/privacy, both Grade 1 at the same 2-3/4 inch backset.

No, and they are not interchangeable. The 11-111 goes into the edge of a bored door under A Series knob trim. A sidelite auxiliary latch like the Accentra YSSL10 mounts on the fixed panel beside a door to secure it, and that one is built for 1-3/4 inch thickness with a thumbturn. If your problem is a rattling sidelite panel rather than a failing knob latch, the 11-111 is the wrong part.
