Deltana G2DLDB Grade 2 Drive-In-Latch Adjustable Backset Deadbolt 2-3/8" to 2-3/4"

One part covers both. The G2DLDB latch adjusts between a 2-3/8 inch and a 2-3/4 inch backset, which are the two standard bore spacings on residential and light commercial doors. For a property manager carrying stock across a building with mixed door preps, that means one deadbolt on the shelf instead of two.

Drive-in means the bolt housing is driven straight into the edge bore instead of being screwed to a mortised faceplate. There is no rectangular pocket to chisel in the door edge, which speeds up new installs and is common on prehung or replacement doors already cut for a round drive-in collar. If your existing door edge is mortised for a flat faceplate latch, a drive-in will leave that pocket exposed.

Single cylinder. Key on the outside, thumbturn on the inside. If you need key operation from both faces, say on a door with glass beside the lock, this is not the one to order, and a double cylinder unit like the Dexter DB2000 double cylinder or the Callan 210S is the configuration to look at instead.

Grade 2 is the medium duty tier under ANSI/BHMA and it is the usual choice for multi-family entries, offices and light commercial openings. The G2DLDB is catalogued for commercial use at that grade. For a high traffic main entrance or anywhere the spec calls out Grade 1, step up instead to something like the Cal-Royal CRB800 or the Design Hardware D1 Series.

The Deltana G2DLDB is a Grade 2 tubular single cylinder deadbolt with an adjustable 2-3/8 or 2-3/4 inch backset. The closest peers are the Cal-Royal CB160, a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, the Arrow DBX61 Grade 2 cylinder x thumbturn deadbolt, and the Dexter DB2000-SCT, a Grade 2 single cylinder deadbolt listed for 1-3/8 to 1-3/4 inch doors. All three are keyed outside and thumbturn inside, the same operation as the G2DLDB.

The Deltana G2DLDB is rated Grade 2. For a higher ANSI grade, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, the Dexter DB1000-SCT is a Grade 1 single cylinder deadbolt for 1-3/8 to 1-7/8 inch doors, and the Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset like the Deltana. The Accentra D111 is also Grade 1, but fixed at a 2-3/8 inch backset, so confirm your bore before specifying it.

The Deltana G2DLDB adjusts between 2-3/8 and 2-3/4 inch backset, so a single SKU fits either standard bore. Other deadbolts with adjustable backsets include the Cal-Royal ED500, a Grade 3 single cylinder deadbolt for 1-3/8 to 1-3/4 inch doors, the Falcon D111 Grade 1 classroom deadbolt with adjustable backset, and the Brinks E2401 Raleigh and E2402 Mendocino single cylinder deadbolts, both with a 4-way adjustable backset. That flexibility matters on a property with mixed bore spacing across doors.

The Deltana G2DLDB is single cylinder, keyed outside with a thumbturn inside. For key-both-sides openings, the Dexter DB2000-DCT is a Grade 2 double cylinder deadbolt for 1-3/8 to 1-3/4 inch doors, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for the same door range, the Delaney LU Series 320601 is a Grade 2 double cylinder deadbolt in stainless steel US32D, and the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors. Verify your local egress code before specifying double cylinder on an exit door.

Among the Grade 2 commercial deadbolts, the Hager 3215 single cylinder with a 1 inch throw and the Hager 3115 cylinder x thumbturn, both carrying a fire rating and fitting 1-3/8 to 1-3/4 inch doors, are the units to specify when the opening is a rated assembly. The Cal-Royal CRB800 heavy duty single cylinder deadbolt carries a UL 3-hour fire rated latch. The Deltana G2DLDB is a Grade 2 commercial tubular deadbolt and is the right choice where a fire label is not part of the opening requirement.

The Deltana G2DLDB is a keyed Grade 2 single cylinder deadbolt supplied as a complete unit. If your facility standardizes on interchangeable cores, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC less core, for 1-3/8 to 1-3/4 inch doors, and the Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D. Those let you install your own core and keep the deadbolts on the same key system as the rest of the building.

The Deltana G2DLDB is a cylinder outside by thumbturn inside. For other trim arrangements, the Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and thumbturn inside, non-keyed, for 1-3/8 to 1-3/4 inch doors. The Corbin Russwin DL3011 and DL3211 are Grade 1 cylindrical deadlocks with cylinder by blank plate, the DL3011 for 1-3/4 to 2-1/4 inch doors and the DL3211 for 1-3/4 inch. The Callan 205S is a Grade 3 one-sided half-bore deadbolt where only one face of the door is prepped.

Yes. It is a tubular bored deadbolt, so it installs in its own cross bore above the latch set and works independently of whatever knob or lever is already there. If you would rather have the deadbolt and lever retract together on one trim, an interconnected lock such as the Falcon H2101 is the different animal to look at.

All three are Grade 2 single cylinder deadbolts. The separator is the latch: the Deltana ships with an adjustable backset drive-in latch that covers both 2-3/8 and 2-3/4 preps without a faceplate mortise. The Arrow DBX61 and the Bravura 310B Elite are catalogued as Grade 2 cylinder x thumbturn deadbolts without that adjustable drive-in latch called out. If your doors are a mixed bag of preps, the Deltana is the one that absorbs the variation.

Look elsewhere for a labeled opening. Where a fire rating has to appear on the submittal, the Hager 3115 and 3215 Grade 2 single cylinder deadbolts are the ones in our range that carry a fire rating on record, and both cover 1-3/8 to 1-3/4 inch doors.

No. The Deltana G2DLDB is a tubular deadbolt that installs in a standard cross-bore and edge bore. The Dormakaba D900 is a small case mortise deadbolt with a D cylinder, and the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch. Mortise bodies require a pocket routed into the door edge and will not drop into a tubular bore, so they are not a swap for the G2DLDB on an existing prep.

The Deltana G2DLDB is a Grade 2 unit flagged for commercial use. For lighter duty openings, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 to 1-3/4 inch doors, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, and the Callan 200S is a Grade 3 single cylinder square trim deadbolt. Note that the ADA thumbturn on the LSD is a feature the G2DLDB record does not claim, so if turn ergonomics are part of your spec that is the one to look at.

The Deltana G2DLDB is a mechanical keyed deadbolt. If you want code or credential access on the same function, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Codelocks CL200 is a surface deadbolt with mechanical code entry and key override if you want no electronics at all.

The Deltana G2DLDB is offered in brushed chrome and polished brass with round trim. For other trim shapes and decorative finishes, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt and the 310RC Elite is a Grade 2 contemporary round, the Bravura 910005 is a Grade 2 rectangle single cylinder deadbolt, and the Emtek #11 Tuscany is a lost wax cast bronze deadbolt. All of those are cylinder by thumbturn like the Deltana, so the function stays the same while the trim changes.

Neither is a substitute for the Deltana G2DLDB, which is a complete keyed Grade 2 tubular deadbolt. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, a frame component rather than a lock. The BEST 8T is a T Series tubular deadbolt tube component, a piece of a BEST lock rather than a standalone deadbolt. If you are replacing a whole deadbolt, order the complete unit.

For thick doors, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock listed for 1-3/4 to 2-1/4 inch doors, the widest range among the commercial deadbolts here. The Dexter DB1000 Series covers 1-3/8 to 1-7/8 inch in both single and double cylinder. The Deltana G2DLDB is a Grade 2 tubular deadbolt whose strength is backset flexibility, adjusting between 2-3/8 and 2-3/4 inch, so it is the pick when bore spacing varies rather than door thickness.

Two: brushed chrome and polished brass. Brushed chrome is the one that blends with most existing commercial lever and closer hardware; polished brass suits older residential and hospitality openings where the rest of the trim is bright brass.

Steel and zinc construction throughout. That is standard for a medium duty tubular deadbolt and it is fine for interior and protected exterior openings.
