Deltana G2RLDB75 Grade 2 Regular Latch, Deadbolt, 2-3/4" Backset

The G2RLDB75 is a 2-3/4 inch backset deadbolt, which is the standard commercial backset on most exterior and commercial openings. If the existing cross-bore in your door measures 2-3/4 inches from the door edge to the center of the hole, this drops straight in. If your door is prepped at 2-3/8 inches, this is the wrong part and you need a 2-3/8 backset deadbolt instead.

It is a Grade 2 deadbolt classified for commercial use. Grade 2 is the medium-duty tier, which suits apartment entries, offices, and multi-family corridors. For a high-traffic or higher-security opening where the spec calls Grade 1, step up to something like the Design Hardware D1 Series or the Delaney LM Series Grade 1 deadbolt.

The G2RLDB75 is a tubular (bored) deadbolt. It installs through a standard cross-bore and edge bore, no lock case pocket to route. If your door is prepped for a mortise case instead, this will not fit and you would want a mortise deadlock like the Dormakaba D900 small case mortise deadbolt or the Emtek 2050 European mortise deadbolt.

The Deltana G2RLDB75 is a Grade 2 deadbolt. For a higher ANSI/BHMA grade in the same single cylinder function, look at the Dexter DB1000-SCT, a Grade 1 cylinder x thumbturn deadbolt for 1-3/8 to 1-7/8 inch doors, the Accentra D111 Grade 1 single cylinder deadbolt with a 2-3/8 inch backset, or the Falcon D111, a Grade 1 heavy duty deadbolt with an adjustable backset. The Delaney LM Series is a Grade 1 single cylinder less-core deadbolt if you are keying into an existing interchangeable core system.

The G2RLDB75 is built for a 2-3/4 inch backset only. If the door prep is unknown or you are stocking one part for mixed openings, an adjustable-backset deadbolt is the safer buy: the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 inch doors, the Falcon D211 is a Grade 2 single cylinder deadbolt, and the Falcon D111 offers an adjustable backset at Grade 1. The Brinks Raleigh E2401 single cylinder deadbolt uses a 4-way adjustable backset.

The Deltana G2RLDB75 is single cylinder, keyed outside with a thumbturn inside. Where a thumbturn is not acceptable, double cylinder options at the same grade include the Dexter DB2000-DCT Grade 2 double cylinder deadbolt for 1-3/8 to 1-3/4 inch doors, the Delaney LU Series Grade 2 double cylinder in stainless steel (US32D), and the Hager 3214 Grade 2 double cylinder deadbolt with a Schlage C keyway. For a keyed outside with blank plate inside, the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock, cylinder x blank, for 1-3/4 inch doors. Confirm your local code before specifying a double cylinder on an egress door.

Several nearby parts share the deadbolt name but not the tubular bored-door application of the G2RLDB75. The Arrow 460 is a mortise lock strike for latchbolt x deadbolt functions, not a lock. The BEST 8T is a tubular deadbolt tube component rather than a complete lockset, and the Baldwin Reserve 8BR0618001 is a deadbolt spacer. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, which require a mortise pocket. The Codelocks CL200 is a surface-mounted deadbolt with key override, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt - both entirely different preps and operation from a keyed tubular deadbolt.

For fire-rated openings, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw and a fire rating, sized for 1-3/8 to 1-3/4 inch doors, and the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway and a fire rating. At Grade 1, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Hager 3118 is a Grade 1 classroom deadbolt with a 6-pin Schlage C cylinder. Match the rating to the door and frame label.

Several Grade 2 single cylinder units cover the same duty level with different trim. The Arrow DBX61 and the Cal-Royal CB160, which adds a tamper-resistant cylinder guard, are direct Grade 2 cylinder-by-thumbturn options. Bravura offers the 310B Elite in traditional round, the 310RC in contemporary round, and the 310SC in square trim if the finish and shape need to match a design package.

A 1 inch strike comes with the deadbolt. On a replacement job the existing strike mortise in the jamb usually accepts it, but check the lip and the depth of the pocket before you pull the old one; a jamb cut for a wider strike plate will leave a gap you need to fill or re-mortise.

Yes, that is the normal use. The G2RLDB75 is a standalone keyed deadbolt, not an interconnected lock, so it bores separately above the existing lockset and operates independently. If you would rather have the latch and deadbolt retract together with one motion on the inside, you want an interconnected lock instead, such as the Falcon H2101 entrance interconnected lock with a single cylinder deadbolt.

No handing to specify. A tubular deadbolt throws a straight bolt into the jamb, so it works on a left or right hand door, inswing or outswing, with no reversing. Handing only matters here in the sense that the cylinder side must face out.

The G2RLDB75 is a Grade 2 commercial deadbolt. For lighter-duty openings, Grade 3 single cylinder options include the Callan 200S with square trim, the Cal-Royal LSD with an ADA ergonomic thumbturn for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal ED500 with adjustable backset. The Callan 205S is a Grade 3 one-sided half-bore deadbolt where only the interior side is needed.

The Deltana G2RLDB75 is offered in Brushed Chrome and Polished Brass. If the trim profile matters for matching existing hardware, Bravura offers the 310B Elite in a traditional round shape, the 310RC Elite in a contemporary round, and the 310SC Elite in a contemporary square, all Grade 2 cylinder x thumbturn deadbolts, plus a Grade 2 rectangle single cylinder deadbolt. The Callan 200S-G2 is a Grade 2 single cylinder with round trim.

The G2RLDB75 is a keyed mechanical deadbolt. Electronic equivalents in the deadbolt format include the Delaney KP400, a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 electronic surface deadbolt in brushed steel and the CL2210 electronic mortise deadbolt, and the Dormakaba Nova-D RFID multihousing smart electronic deadbolt. Note that the surface and mortise versions do not use the same door prep as a tubular bored deadbolt.

The G2RLDB75 is keyed with a single cylinder. Where no key is wanted on the outside, the Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate outside and thumbturn inside, for 1-3/8 to 1-3/4 inch doors. If you want the same opening keyed later with an interchangeable core, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core, also for 1-3/8 to 1-3/4 inch doors.

Two finishes: brushed chrome and polished brass. Brushed chrome is the usual match for commercial openings already running satin chrome or brushed nickel trim, while polished brass suits older brass lever and knob sets you are trying to keep consistent across a building.
