Schlage 11-118 - A Series Spring Latch, Square Corner, 1-1/8" x 2-1/4" Faceplate, 3-3/4" Backset

No. The 11-118 is a 3-3/4 inch backset latch, so it only suits an opening prepped at 3-3/4 inches, well outside the 2-3/8 and 2-3/4 inch backsets used on most cylindrical prep. Measure door edge to bore center before you order. For a 2-3/8 or 2-3/4 prep, ZenSupply carries the Deltana G1RLE238 and G1RLE275 Grade 1 entry latches at those two backsets, with the G1RLP238 and G1RLP275 covering passage and privacy.

Yes. The 11-118 is the A Series spring latch, sold as a replacement part and built to work with the lock trim. Stainless steel, square corner faceplate measuring 1-1/8 x 2-1/4 inches, 3-3/4 inch backset. The one thing worth checking before ordering is that backset: pull the old latch, measure from the door edge to the center of the bore, and confirm it reads 3-3/4 inches. That dimension decides fit more than anything else on the part.

Both. A Series latches are adjustable for flat or beveled edge doors, so the same 11-118 covers a square-edge door and a beveled one without ordering a second part number. That matters if you keep spares on the shelf for a mixed building, since one bin covers every 3-3/4 inch backset opening regardless of how the edge was machined.

Only if the existing pocket is square cornered and sized to 1-1/8 x 2-1/4 inches. The 11-118 faceplate is square corner at that size. A pocket routed with radius corners, the other common shape on cylindrical latch prep, will leave the corners of the new plate proud and has to be chiseled square to seat flush. Hold the old latch face against the new one before you cut anything.

The 11-118 is a spring latch, so the bolt is spring loaded with no auxiliary deadlocking plunger riding beside it. That is fine on interior and non-keyed openings. On a keyed exterior door most specs call for a deadlatch instead, because the plunger stops the bolt being pushed back with a card. ZenSupply stocks the Lockey M230, a deadlocking spring latch with adjustable backset, and a Dexter deadlatch for C1000 Series locks, though that one is built for the Dexter chassis and will not go into a Schlage A Series lock.

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. Those are standard BHMA finish numbers, so match the number stamped on your existing Schlage trim rather than matching by eye. 605 and 606 are both brass and read very differently once they are up in a corridor, and the same goes for 625 against 626.

It is a commercial-duty part, built in stainless steel rather than plated steel. Stainless resists corrosion, which is what you want on an opening that sees moisture, cleaning chemicals or outside air, so it holds up in unconditioned stairwells and doors facing the weather as well as it does on interior traffic.

Different jobs entirely. The 11-118 is the latch that lives inside a Schlage A Series cylindrical lock, in the edge of the active door. A sidelite auxiliary latch such as the Accentra YSSL10 mounts on the narrow fixed panel next to the door and secures it with a thumbturn; the YSSL10 is listed for 1-3/4 inch doors and its thumbturn is ADA compliant. If you are rebuilding a lockset, the 11-118 is the part. If you are locking down the panel beside the door, it is not.

No. The Schlage 11-118 A Series spring latch is built for a 3-3/4 inch backset with a square corner 1-1/8 inch by 2-1/4 inch faceplate, so it lands in the door prep that was bored 3-3/4 inches from the door edge to the center of the lock hole. The Deltana Grade 1 regular latches are made in the two standard residential and light commercial backsets: the G1RLE238 at 2-3/8 inches and the G1RLE275 at 2-3/4 inches. Backset is not adjustable on those parts, so a 2-3/8 or 2-3/4 inch latch tail will not reach the retractor of a lock set 3-3/4 inches back. Measure from the door edge to the center of the existing lock bore before ordering: 3-3/4 inches calls for the Schlage 11-118, and a 2-3/8 or 2-3/4 inch measurement points to the matching Deltana part.

That plunger is the mark of a deadlatch, and it is a different part from a plain spring latch. The Schlage 11-118 is an A Series spring latch in stainless steel, square corner faceplate, 3-3/4 inch backset, and it is the retraction part that pairs with A Series lock trim. If what came out of the door was a deadlatch, match it to a deadlatch: the Dexter C1000 series deadlatch is made for the C1000 chassis, and the Lockey M230 is a deadlocking spring latch that comes as part of a mechanical keyless digital combination lock rather than as a loose replacement latch. Take the old part to the bench and look at the faceplate corner shape, the backset, and whether there is an auxiliary plunger before you order - a spring latch and a deadlatch of the same backset are not interchangeable in an opening that was specified for one or the other.

A sidelite panel is a different piece of hardware from a door latch. The Schlage 11-118 is a commercial A Series spring latch that installs in a bored door prep at a 3-3/4 inch backset and operates from A Series lock trim. For the sidelite itself, the Accentra YSSL10 is a security sidelite auxiliary latch with an ADA compliant thumbturn, listed for 1-3/4 inch door thickness and carrying a fire rating. That is the part written for the fixed panel next to the active leaf, and the thumbturn is what makes it workable where accessible operation is required. Use the YSSL10 on the sidelite and the 11-118 on the active bored door where the trim and the 3-3/4 inch backset match.

Going keyless means changing the lock, not the latch. The Schlage 11-118 is a replacement spring latch that serves an existing A Series lock and its trim - it does not change how the door is operated. The Lockey M230 is a mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, and it lists a door thickness range of 1-1/8 inch to 2 inch. Thickness matters on the M230 because the lock body has to clamp through the door, so measure the leaf before ordering; backset is less of a constraint there since it adjusts. Keep the 11-118 on the list for the openings you are leaving keyed, where the A Series trim stays and only the worn latch is coming out.
