Deltana ZDR Solid Brass Elite Series Zinc Modern Low Profile Round Deadbolt Lock, Grade 3

No. The Deltana ZDR Elite Series round deadbolt is specified for a 1-3/8 inch door with a 2-3/8 inch backset. On a standard 1-3/4 inch commercial door you want a deadbolt rated across that range instead, such as the Hager 3215 or the Dexter DB2000 single cylinder, both listed for 1-3/8 to 1-3/4 inch doors.

Single cylinder. Key on the outside, thumbturn on the inside. If you need key access from both faces (common on glass-adjacent or sidelight doors where a burglar could reach the turn), look at a double cylinder deadbolt instead, like the Baldwin Reserve Contemporary Round or the Callan 210S.

The ZDR uses the Schlage C keyway, so it works with the same C-section keys and pinning as the rest of a Schlage C system. That makes it straightforward for a locksmith or property manager to bring it onto an existing residential-style master key setup rather than carrying a separate key.

Grade 3 is the light-duty ANSI/BHMA tier, aimed at residential and low-traffic openings. For a unit entry in a building you own and control, it holds up. For a high-turnover multifamily entry, a lobby, or anything you want to standardize across a commercial facility, step up: the Cal-Royal CB160 and Bravura 310RC are Grade 2, and the Accentra D111 and Design Hardware D1 are Grade 1.

It is a tubular deadbolt on a 2-3/8 inch backset, which is the standard prep on most residential entry doors: a 2-1/8 inch cross bore through the face and a 1 inch edge bore. If the door you are replacing off has that prep at 2-3/8 backset, the ZDR drops in. If your existing bolt is set at 2-3/4 backset, it will not line up, and you would want a deadbolt with an adjustable backset such as the Cal-Royal ED500 or the Brinks Raleigh.

Deadbolt only. The ZDR throws a bolt when you key it or turn the thumbturn, and it does nothing to hold the door closed on its own. You still need a passage, entry, or keyed knob or lever in the lower bore. If you would rather have one unit doing both, an interconnected lock such as the Falcon H2101 combines an entrance lockset with a single cylinder deadbolt.

The Deltana ZDR is a Grade 3 single cylinder tubular deadbolt. Where a fire rating governs the opening, the Hager 3215 single cylinder deadbolt with 1 inch throw is a Grade 2 commercial lock carrying a fire rating for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. Both are cylinder x thumbturn, the same operation as the ZDR.

The Deltana ZDR is a Grade 3 single cylinder tubular deadbolt. If the specification calls for Grade 1, the Dexter DB1000 single cylinder deadbolt is a Grade 1 cylinder x thumbturn deadbolt covering doors 1-3/8 inch to 1-7/8 inch thick, and the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset covering 1-3/8 inch to 1-3/4 inch doors. Both keep the same single cylinder outside key, inside thumbturn operation as the ZDR.

The Deltana ZDR is listed for a 1-3/8 inch door with a 2-3/8 inch backset. For a 1-3/4 inch leaf at the same grade, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset covering 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal LSD is a Grade 3 single cylinder deadbolt over the same thickness range with an ADA ergonomic thumbturn. Both are cylinder x thumbturn like the ZDR.

The Deltana ZDR is single cylinder only, meaning key outside and thumbturn inside. For keyed operation on both sides with similar round contemporary trim, the Baldwin Reserve Double Cylinder Contemporary Round Deadbolt is a double cylinder function, and the Emtek 8323 Modern Disc Deadbolt is a brass double cylinder. If grade matters, the Callan Model 210S is a Grade 3 double cylinder deadbolt and the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 inch to 1-3/4 inch doors.

The Deltana ZDR ships with a Schlage C keyway. Hager also builds to Schlage C: the 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway, the 3118 is a Grade 1 classroom deadbolt with Schlage C and a 6-pin cylinder, and the 3214 is a Grade 2 double cylinder deadbolt with Schlage C. All three cover 1-3/8 inch to 1-3/4 inch doors. The Dormakaba D900 small case mortise deadbolt is also supplied with SC keyways, keyed different.

The Deltana ZDR is built to a 2-3/8 inch backset. When the prep is unconfirmed or mixed across a set of doors, an adjustable-backset unit removes the guess: the Brinks Raleigh Series round single cylinder deadbolt has a 4-way adjustable backset, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Falcon D111 is a Grade 1 deadbolt with adjustable backset.

Several deadbolt-named items are not drop-in for a tubular bored deadbolt like the Deltana ZDR. The Arrow 460 is a mortise lock strike, not a lock. The Baldwin 8BR0618001 is a deadbolt spacer, and the BEST 8T is a tubular deadbolt tube component rather than a complete lock. The Emtek 2051 round unit is a European mortise deadbolt with integrated roller latch, which needs a mortise pocket, and the Codelocks CL200 is a surface mounted deadbolt with key override. None of these fit a standard bored deadbolt prep.

The Deltana ZDR is a single cylinder deadbolt with an inside thumbturn. For classroom or deadlock functions with a cylinder on one side and a blank the other, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock, cylinder x blank, for 1-3/4 inch to 2-1/4 inch doors, and the DL3211 is the same cylinder x blank arrangement for 1-3/4 inch doors. The Arrow E61 is a Grade 2 single cylinder deadlock prepped for SFIC less core, covering 1-3/8 inch to 1-3/4 inch doors, if the facility standardizes on interchangeable cores.

The Deltana ZDR is a Grade 3 zinc deadbolt. Where cycle counts and abuse are higher, the Design Hardware D1 Series is an extra heavy duty Grade 1 double cylinder deadbolt for 1-3/4 inch doors, the Falcon D111 is a heavy duty Grade 1 deadbolt with adjustable backset, and the Kaba Ilco 4500 Series is a heavy duty professional deadbolt. If a single cylinder function must be kept, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset, matching the ZDR backset.

The ZDR is built on a zinc substrate within Deltana's Elite Series brass line. Zinc die cast is the body material, so treat it as an interior-side or protected-entry choice rather than a fully exposed coastal opening. If you want cast bronze or solid brass through and through, the Emtek #11 Tuscany is lost wax cast bronze and the Emtek 8323 Modern Disc is brass.

The Deltana ZDR uses a low profile round rose on a single cylinder tubular deadbolt. For square trim in the same single cylinder configuration, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt, the Callan Model 200S is a Grade 3 single cylinder square trim deadbolt, and the Brinks Mendocino Series is a contemporary square single cylinder deadbolt with a 4-way adjustable backset. The Baldwin Reserve Contemporary Square Deadbolt is square trim but a double cylinder function.

The Deltana ZDR is keyed, single cylinder, with a Schlage C keyway. If key control is not wanted, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and thumbturn inside for 1-3/8 inch to 1-3/4 inch doors. For code entry rather than a key, the Codelocks CL2200 is an electronic surface deadbolt in brushed steel and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote.

The Deltana ZDR is a through-bored single cylinder deadbolt with trim on both faces. Where only the interior face gets hardware, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt, which needs no cross bore through the leaf. For a surface applied approach, the Codelocks CL200 is a surface mounted deadbolt with key override.

Three: Oil Rubbed Bronze, Brushed Nickel, and Polished Chrome. That covers the usual pairing choices, warm dark trim, satin, and bright. If you are matching a set of doors, pick the finish once and order all openings the same way, since the ZDR is a low profile round rose with no other trim shape option.
