Deltana G2RLP275 Grade 2 Regular Latch, Passage/Privacy, 2-3/4" Backset

Yes, the G2RLP275 is built to a 2-3/4 inch backset, which is the standard commercial bore spacing (2-3/8 inch is the other common one, typically residential). Measure from the door edge to the center of the bore hole: if that comes out at 2-3/4 inches, this latch drops in. If your door is bored at 2-3/8 inches, you need a 2-3/8 inch latch instead, not this one.

It is a drive-in latch. The latch body is driven into the cross-bore in the door edge rather than mortised for a faceplate, so there is no routing of the edge and no faceplate screws. That matters two ways: your door edge has to be prepped as a plain round cross-bore (no rectangular mortise), and if your existing door is already mortised for a faceplate latch, a drive-in will leave that cutout exposed and you want a faceplate-style latch instead.

The strike is 1-1/8 x 2-1/4 inches, which is the common full-lip cylindrical strike size. If your frame already has that prep from a previous cylindrical lockset, the latch lines up with it. Frames prepped for a T-strike or a 4-7/8 inch ANSI strike are a different cutout and will need the opening reworked or a filler.

Grade 2 and classed for commercial use. For a property manager or MRO buyer, that puts it in the range for apartment interiors, offices, and light commercial corridors rather than high-cycle main entrances, where Grade 1 is the usual spec. If a facility standard on your drawing calls out Grade 1 cylindrical hardware, this latch does not meet it.

Yes. The latch is a passage/privacy function, meaning the latch itself just holds the door closed and retracts from either side by turning the knob or lever. It is the same latch whether the trim is a plain passage set or a privacy set with a thumbturn and emergency release, because the locking happens in the trim, not in the latch. What it will not do is accept a key, so it is not the part for a keyed entry or a storeroom function.

Yes, the G2RLP275 is sold as a single latch, each, so you can swap only the failed mechanism and keep the existing knobs or levers. Two things have to line up for that to work: your door bore must be 2-3/4 inch backset, and the door edge must be prepped for a drive-in body rather than a mortised faceplate. Both of those are quick to check with a tape before you order a batch for a building.

Drive-in makes sense when you control the prep or the doors are factory bored round with no edge mortise: installation is faster and there is nothing to rout. A faceplate latch is the better call on existing doors that already carry a rectangular edge mortise, on metal frames where the faceplate carries the screws, and anywhere a facility keeps one standard latch across hundreds of openings that were originally mortised. The G2RLP275 is the drive-in version at 2-3/4 inch backset, Grade 2.

One latch covers both hands. A cylindrical passage/privacy latch of this type has a reversible latchbolt, so the same part serves a left hand or right hand opening without ordering a hand. You only need to make sure the bolt bevel faces the frame when it goes in.

Mostly it matters at the door edge and the strike. The latch comes in Brushed Chrome and Polished Brass, and on a drive-in latch the visible part is the collar ring at the door edge plus the strike in the frame. Pick the one that matches your existing trim so the edge does not read as a mismatch. Function is identical between the two.

Steel and zinc construction. That is a solid choice for interior openings and typical corridor and unit doors. For openings taking direct weather, salt air, or washdown, a plated steel and zinc latch is not the material you want exposed long term, so keep it on the interior side of the building envelope.
