Deltana G1RLP275 Grade 1 Regular Latch, Passage/Privacy, 2-3/4" Backset

It is rated Grade 1 and catalogued for commercial use, built in steel and zinc. Grade 1 is the highest ANSI/BHMA durability tier, so it suits high traffic openings like schools, offices and multi-family corridors rather than light residential duty.

The G1RLP275 is a regular latch, not a deadlatching one. It has no auxiliary deadlocking plunger beside the latchbolt. For an exterior or keyed-entry opening where you want anti-carding protection, specify a deadlatch instead, such as the Dexter deadlatch for the C1000 Series or the Schlage 16-480 deadlatch.

The Deltana G1RLP275 is fixed at a 2-3/4 inch backset, so it will not drop into a 2-3/8 inch bore. For that opening, the Schlage 16-480 deadlatch is adjustable to either 2-3/8 or 2-3/4 inch backset with a 1 inch by 2-1/4 inch face and square corner, and the Schlage 16-228 is also adjustable between the two backsets with a 1-1/8 inch by 2-1/4 inch face. Either covers a mixed-backset building without having to stock two part numbers.

The Deltana G1RLP275 is a regular latch for a commercial bored lockset and is not a sidelite unit. For a narrow sidelite, the Accentra YSSL10 security sidelite auxiliary latch is built for that application, is fire rated, fits 1-3/4 inch door thickness, and comes with an ADA compliant thumbturn.

They are both cylindrical lock latches, but they are not graded the same. The Deltana G1RLP275 is a Grade 1 latch, while the Dexter deadlatch for the C1000 series is Grade 2. If the door schedule calls out Grade 1, the Deltana is the one that meets it; the Dexter is the match when you are servicing an existing C1000 series lock.

It is a passage/privacy latch, so it pairs with non-keyed knob or lever sets: passage sets that always retract freely, and privacy sets with a thumbturn and emergency release. It is not the latch for a storeroom or classroom function.

Tubular, for a standard cylindrical bored lockset prep. It drops into the cross bore and edge bore of a bored door, so it is not a substitute for a mortise lock body.

Only if the bore is actually at 2-3/4 inches. The Deltana unit is fixed at that dimension with no adjustment. If your openings vary across a building, an adjustable latch that covers both 2-3/8 and 2-3/4 inches, like the Schlage 16-228 or the 12-289, keeps one part number on the truck.

No. The Deltana G1RLP275 is a regular spring latch for a bored cylindrical lock in a passage/privacy function. The Schlage 12-289 is a deadbolt latch for the B500 series and the 12-630 is a deadbolt latch for the B600, B700 and B800 series. Those go in the deadbolt bore above the lockset, not in the knob or lever bore, so they are an addition to the opening rather than a substitute.

The Deltana G1RLP275 is a latch component only - it is the steel and zinc latch that goes behind a separate passage or privacy trim. The Lockey M230 is a complete mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, fitting doors 1-1/8 to 2 inches thick. Choose the M230 when you want code entry with no key; choose the Deltana when you are replacing the latch in an existing bored lockset.

The Deltana G1RLP275 is a regular spring latch, which is the right choice for interior passage and privacy doors where the latch is not the security point. On an exterior or keyed entry door, a deadlatch with its auxiliary plunger resists carding - the Schlage 16-480 deadlatch for the S200 series is one, with a 1 inch by 2-1/4 inch square corner face and adjustable 2-3/8 or 2-3/4 inch backset.

Two: Brushed Chrome and Polished Brass. Pick the one that matches the trim on the opening, since the latch face and strike show at the door edge.

It is sold each, as the latch mechanism only. Knob or lever trim, and the strike if you need a new one, are ordered separately.
