Deltana G1RLE275 Grade 1 Regular Latch Entry, 2-3/4" Backset

It's a regular latch, meaning a plain spring latch with no auxiliary deadlocking plunger alongside the latchbolt. That's fine behind a locked knob or lever on an interior or secondary opening, but on an exterior door where the latch face is reachable a deadlatch is the better choice because the auxiliary plunger blocks the bolt from being carded back. Dexter's deadlatch for the C1000 series and Schlage's 16-480 are deadlatching options.

Yes. It carries an ANSI/BHMA Grade 1 rating, which is the highest of the three grades and the level normally specified for commercial and institutional openings. Deltana also classes it as a commercial part rather than residential, so it's the right latch for multi-family corridors, schools, and offices rather than a light-duty house door.

The Deltana G1RLE275 is a fixed 2-3/4 inch backset latch, so it will not drop into a 2-3/8 inch bore. The Schlage 16-228 for the S200 and CS210 series is adjustable to either 2-3/8 or 2-3/4 inch backset with a 1-1/8 by 2-1/4 inch face and square corner, and the Schlage 16-480 deadlatch for the S200 series is also adjustable between the two backsets with a 1 by 2-1/4 inch face. Either covers the opening where the backset is uncertain or where you are standardizing across doors bored both ways.

They are not equivalent on grade. The Deltana G1RLE275 is a Grade 1 entry latch, while the Dexter deadlatch for the C1000 series is Grade 2. If your spec or facility standard calls for ANSI/BHMA Grade 1 on the opening, the Deltana is the one that meets it; the Dexter part is built for the C1000 series chassis and carries the lower grade.

It's a tubular latch for a cylindrical (bored) lockset, the knob or lever type installed through a round cross-bore in the door face with the latch running in from the edge. It is not a mortise lock component and will not go into a mortise pocket.

Yes, it's built as an entry function latch, so it pairs with keyed entry knob and lever sets that lock from the inside and release with a key or by turning the inside trim. It carries no function of its own beyond throwing and retracting the spring latch.

No. A 2-3/4 inch backset needs a wide enough stile to take the cross-bore that far back from the edge, so it does not suit a sidelite or narrow stile opening. For a sidelite, the Accentra YSSL10 security sidelite auxiliary latch is purpose built for that application and is listed for 1-3/4 inch doors with a fire rating.

For a fire-rated application, the Accentra YSSL10 security sidelite auxiliary latch carries a fire rating and is built for 1-3/4 inch doors, and it includes an ADA compliant thumbturn. The Deltana G1RLE275 is a Grade 1 commercial entry latch with a 2-3/4 inch backset for standard cylindrical lock prep. Match the part to the opening: the YSSL10 is an auxiliary latch for sidelite and narrow stile work, the Deltana is the replacement latch for a bored entry lockset.

No - those are deadbolt latches, not entry latches. The Schlage 12-289 is a B500 series deadbolt with an adjustable 2-3/8 or 2-3/4 inch backset and a 1 by 2-1/4 inch face with 1/4 inch round corner, and the 12-630 is a B600/700/800 series deadbolt at a fixed 2-3/8 inch backset with a 1-1/8 by 2-1/4 inch face and square corner. The Deltana G1RLE275 is a tubular entry latch for a bored lockset, so it retracts with the knob or lever rather than a thumbturn or key throw.

Two finishes: brushed chrome and polished brass. The exposed part is the latch face on the door edge, so property managers standardizing a floor usually pick the one matching the existing knobs and strikes. Brushed chrome reads with satin nickel and chrome trim, polished brass with brass trim.

No handing to specify. It's a tubular cylindrical latch sold as a single each, and the bolt reverses for left or right hand doors the way bored latches normally do. You order by backset and finish only.
