Baldwin Estate 8231 Traditional 2-1/8" Single Cylinder Deadbolt

Yes. The Estate 8231 ships with an adjustable latch that sets to either a 2-3/8 inch or a 2-3/4 inch backset, so it drops onto either of the two standard residential bore layouts without re-drilling the door edge. Measure from the door edge to the center of the 2-1/8 inch cross bore and set the latch to match.

The 8231 uses Baldwin's C keyway, so it keys into an existing Baldwin C-keyway system. Order it keyed alike if you want several doors on one key, or keyed different if each opening gets its own, and give the key code at order time if you are adding to a system already in place.

The Baldwin 8231 is single cylinder: key outside, thumbturn inside. That is the right choice for a solid door, and it is what most codes want on an egress door because you can get out without a key. If the door has glass within arm's reach of the bolt and you have decided a key-both-sides bolt is what you want, a double cylinder such as the Emtek 8323 Modern Disc or the Callan 210S is the version to look at instead.

The 8231 is a residential deadbolt, built for house and condo entry doors where the finish and the traditional trim matter. For apartment or commercial entries taking heavy traffic, look at a graded commercial bolt instead: the Accentra D111 and the Dexter DB1000 are Grade 1 single cylinder deadbolts, and the Hager 3215 is a Grade 2 commercial bolt with a 1 inch throw for 1-3/8 to 1-3/4 inch doors.

On a door already bored for a tubular deadbolt at 2-1/8 inches with a 2-3/8 or 2-3/4 inch backset, the 8231 goes straight in. That is the common residential prep. What it will not do is replace a mortise deadbolt or a European-style mortise bolt like the Emtek 2050, those sit in a pocket routed into the door edge and the openings are not interchangeable.

The Baldwin Estate 8231 is a residential single cylinder deadbolt in cylinder x thumbturn function. If the opening calls for a Grade 1 bolt in the same cylinder x thumbturn arrangement, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset, and the Dexter DB1000 Series single cylinder deadbolt is Grade 1 for doors 1-3/8 inch to 1-7/8 inch thick. The Deltana CL200LM is another Grade 1 single cylinder deadbolt in cylinder x thumbturn. All three keep the keyed outside and turn piece inside that the 8231 provides.

The Baldwin Estate 8231 is single cylinder with a turn piece on the interior, which is what a glazed opening usually rules out. Double cylinder deadbolts key both sides instead: the Delaney LU Series is a Grade 2 double cylinder deadbolt, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for doors 1-3/8 inch to 1-3/4 inch thick, and the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt for 1-3/4 inch doors. The Emtek 8323 Modern Disc deadbolt is a brass double cylinder if the trim needs to stay decorative.

Both are single cylinder deadbolts in cylinder x thumbturn function, so the door prep and the way they operate line up. They differ in what they are built for: the Baldwin Estate 8231 is a residential brass deadbolt with a Traditional design and C-keyway cylinder, while the Hager 3215 is a Grade 2 commercial lock with a 1 inch throw, a fire rating, and a door thickness range of 1-3/8 inch to 1-3/4 inch. Choose the 3215 where a fire rated commercial bolt is specified and the 8231 where the trim has to match a decorative brass suite.

The Baldwin Estate 8231 is a bored deadbolt with an adjustable 2-3/8 inch or 2-3/4 inch backset, so it takes a standard cross-bore and edge bore. Several deadbolts in the same function need different prep entirely: the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, the Dormakaba D900 is a small case mortise deadbolt, and the Codelocks CL200 is a surface mounted deadbolt with key override. The Arrow 460 is a mortise lock strike rather than a lock body at all.

The Baldwin Estate 8231 is a keyed deadbolt with a C-keyway cylinder outside and a turn piece inside. Where the outside should have no cylinder, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and thumbturn inside, for doors 1-3/8 inch to 1-3/4 inch. The Callan Model 205S is a Grade 3 one sided half-bore deadbolt, which only bores one face of the door.

The Baldwin Estate 8231 is an entry function residential deadbolt with a fixed C-keyway cylinder. Facilities that key to a master system or need classroom function usually go a different way: the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors, and the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep supplied less core. The Deltana CL200LAIC is a Grade 2 single deadbolt with a 2-3/4 inch backset prepped for an interchangeable core.

The Baldwin Estate 8231 is a residential deadbolt. Where the opening needs a fire rated bolt, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch in cylinder x thumbturn function, and the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway, fire rated, for doors 1-3/8 inch to 1-3/4 inch thick.

No handing to specify. The 8231 is reversible, so the same bolt works on a left hand or right hand door and on an inswing or outswing opening. Keyed cylinder outside, turn piece inside, either way you hang it.

Nine finishes, all on a brass base: 003 Polished Brass PVD, 031 Non-Lacquered Brass, 033 Vintage Brass, 050 Satin Brass Black, 056 Lifetime PVD Satin Nickel, 102 Oil Rubbed Bronze, 112 Venetian Bronze, 190 Satin Black, and 402 Distressed Oil Rubbed Bronze. The PVD finishes (003 and 056) hold their color; 031 non-lacquered brass is meant to live and patina over time, so pick that one only if you want the door to change.

A reinforcing strike is included. It is high-grade steel and the bolt case itself is heavy gauge steel, which is the part that matters on a kick-in: the strike screws are what hold the frame. Nothing extra to order unless your jamb prep does not match the strike cutout already in the frame.

No. The 8231 is an entry function bolt, keyed outside and thumbturn inside, so anyone on the inside can throw or retract it by hand. For a classroom deadbolt where the inside is not free-turning, the Falcon D111 (Grade 1) and Falcon D211 (Grade 2) are classroom function bolts, and the Hager 3118 is a Grade 1 classroom deadbolt on the Schlage C keyway.

The Baldwin Estate 8231 is a brass Estate Series deadbolt sold in nine finishes including Polished Brass PVD and Oil Rubbed Bronze. For a plainer round or square bolt in the same cylinder x thumbturn function, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 inch to 1-3/4 inch doors, the Callan Model 200S is a Grade 3 single cylinder with square trim, and the Bravura 310B Elite is a Grade 2 traditional round deadbolt. The Brinks Raleigh Series is a transitional round single cylinder deadbolt with a 4 way adjustable backset.

The Baldwin Estate 8231 is a mechanical single cylinder deadbolt operated by key outside and turn piece inside. For coded or credential access on the same door, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is an electronic surface deadbolt in a brushed steel finish, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Dormakaba Nova-D is an RFID multihousing smart deadbolt for portfolios keying whole buildings to credentials.

The Baldwin Estate 8231 uses a standard turn piece on the interior. Where an easier grip is wanted, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, in the same cylinder x thumbturn function, for doors 1-3/8 inch to 1-3/4 inch thick.

The Baldwin Estate 8231 pairs a heavy gauge steel deadbolt case with a reinforcing strike of high-grade steel. If a guarded cylinder is the priority, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard in cylinder x thumbturn function, and the Detex DX Series is a hinge side locking deadbolt with multi-point security for openings attacked at the hinge edge.
