Baldwin Estate 8231 Traditional 2-1/8" Patio Deadbolt

The Estate 8231 is a patio-function deadbolt, which means there is no key cylinder at all. It throws and retracts from the inside turn piece only, so it locks a door from the inside and cannot be opened from the outside by anyone. That makes it right for a patio slab, a back door, or a bedroom or interior door where you want a positive lock but no outside key. If someone needs to unlock the door from outside with a key, this is the wrong part and a cylinder x thumbturn deadbolt is what you want.

In most cases yes, because the 8231 has an adjustable backset that sets to either 2-3/8 or 2-3/4 inches, the two standard bore positions on residential doors. Measure from the door edge to the center of the existing bore, set the latch to match, and the trim covers the same 2-1/8 inch cross bore this bolt is built for. If your old hole was drilled at some other backset, no adjustable deadbolt will pick it up.

It is built and rated as residential hardware, not commercial. For a leased entry door, a corridor door, or anything in a commercial facility, go with a graded commercial deadbolt: the Accentra D111 and the Delaney LM Series are Grade 1 single cylinder units, and the Cal-Royal CB160 or Dexter DB2000 are Grade 2 options. The 8231 belongs on a patio or secondary door in a house or a single-family rental where a decorative brass finish matters more than a cycle grade.

The Baldwin Estate 8231 is a residential patio deadbolt with a turn piece inside and no key. The Arrow E60 exit deadlock is the closest non-keyed peer with a commercial grade behind it: it is Grade 2, blank plate outside by thumbturn inside, and fits doors 1-3/8 inch to 1-3/4 inch. Functionally both give you inside-only operation with a blank exterior. The difference is the trim and the pedigree - the 8231 is a brass Estate Series residential piece, the E60 is a plain exit deadlock built to a Grade 2 commercial rating.

The Estate 8231 is a patio function deadbolt: it is not keyed, and the inside is a turn piece only, so there is no outside cylinder to carry a key. When the opening needs outside key control, a cylinder x thumbturn deadbolt is the swap. The Dexter DB1000 single cylinder deadbolt is Grade 1 cylinder x thumbturn and covers doors 1-3/8 inch to 1-7/8 inch. The Hager 3115 is a cylinder x thumbturn deadbolt on a Schlage C keyway for doors 1-3/8 inch to 1-3/4 inch. Both keep the inside thumbturn the 8231 already gives you and add the exterior cylinder it deliberately leaves off.

The Estate 8231 operates from a turn piece on the inside, which is the wrong answer next to breakable glass. A double cylinder deadbolt takes a key on both faces instead. The Hager 3214 is a Grade 2 double cylinder deadbolt on a Schlage C keyway for doors 1-3/8 inch to 1-3/4 inch. The Dexter DB1000 double cylinder is Grade 1 for doors 1-3/8 inch to 1-7/8 inch, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt if the decorative trim matters. Check the local egress code first - many jurisdictions restrict double cylinder deadbolts on a dwelling exit door.

The Estate 8231 is a residential deadbolt in a brass Estate Series trim. On an opening where a specification calls for an ANSI grade, the Grade 1 peers are the ones written to it: the Corbin Russwin DL3011 cylindrical deadlock for doors 1-3/4 inch to 2-1/4 inch, the Design Hardware D1 Series extra heavy duty double cylinder deadbolt for 1-3/4 inch doors, the Delaney LM Series Grade 1 less core deadbolt for interchangeable core keying, and the Accentra D111 Grade 1 with a 2-3/8 inch backset. Note the D111 is fixed at a 2-3/8 inch backset where the 8231 adjusts between 2-3/8 inch and 2-3/4 inch, so confirm the existing bore before you order it.

The Estate 8231 is a residential patio deadbolt. Where a fire rated opening is involved, choose a deadbolt carrying that rating: the Hager 3115, 3215, 3118 and 3214 are all listed with a fire rating and fit doors 1-3/8 inch to 1-3/4 inch, and the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. All are cylinder x thumbturn rather than patio function. Confirm the assembly listing for the specific door and frame before ordering.

No handing to specify. The 8231 is reversible, so the same box works on a left or right hand door. Order by finish and be done.

A reinforcing strike is included, made of high-grade steel, along with a deadbolt case formed of heavy gauge steel. You are not sourcing a strike separately. What you do need to check is the frame: the reinforcing strike is meant to be fastened through into the framing, so on a hollow wood jamb plan on long screws reaching the stud.

They look interchangeable on a spec sheet and are not. The Baldwin Estate 8231 is a patio deadbolt with a turn piece inside and an adjustable 2-3/8 inch or 2-3/4 inch backset, so it goes through a standard full cross-bore. The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt - it drills only partway through the door and presents nothing on the far face. Use the 205S where the outside face must stay completely blank and unbored; use the 8231 where the door is already bored through for a standard deadbolt and you want a finished trim ring on both sides.

The Estate 8231 ships with an adjustable backset that sets to 2-3/8 inch or 2-3/4 inch, which is what lets one part number cover both common door preps. Among the alternatives, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for doors 1-3/8 inch to 1-3/4 inch, and the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset. The Brinks Raleigh E2401 uses a four way adjustable backset. If you are buying for a mixed set of openings and cannot survey every bore first, all four absorb the difference in the field.

The Estate 8231 is built around the C keyway, so a property standardizing on Schlage C keys can extend that system across other doors. The Hager 3115 is a cylinder x thumbturn deadbolt with a Schlage C keyway, the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder, and the Hager 3214 is a Grade 2 double cylinder deadbolt on the same Schlage C keyway. All three fit doors 1-3/8 inch to 1-3/4 inch. Keep in mind the 8231 itself is a non-keyed patio function, so it takes no key of any keyway - the C keyway matters for the rest of the Baldwin Estate line you are matching it to.

Only if you are prepared to change the door prep. The Baldwin Estate 8231 is a bored deadbolt on an adjustable 2-3/8 inch or 2-3/4 inch backset, so it drops into a standard cross-bore. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, in square and round trim respectively, and require a mortise pocket routed into the door edge. The Dormakaba D900 is a small case mortise deadbolt, also a mortise prep. On an existing bored door the 8231 and the other bored deadbolts are the drop-in; the mortise units are a different opening entirely.

The Estate 8231 operates on a turn piece from the inside. Where thumbturn ergonomics are being specified, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 inch to 1-3/4 inch, and it is the peer written for that requirement. The LSD is cylinder x thumbturn, so it adds an outside key the 8231 does not have. If the opening simply needs inside-only operation and the turn piece shape is not being specified, the 8231 keeps the brass Estate trim.

The Estate 8231 is non-keyed patio function, so it never enters a core system. Where the same opening has to join an IC keying program, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC less core, fitting doors 1-3/8 inch to 1-3/4 inch. The Deltana CL200LAIC is a Grade 2 single cylinder deadbolt with an interchangeable core prep and a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt. All three ship without the core so your locksmith supplies it from the existing system.

It changes what the lock does. The Estate 8231 is a mechanical patio deadbolt with a turn piece inside and no key at all, which suits a door secured only from within. If the unit needs credential control instead, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, the Nova-D is an RFID multihousing smart electronic deadbolt, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. Codelocks offers a mechanical middle ground - the CL200 is a surface deadbolt with key override, light duty.

Four: 003 Polished Brass PVD, 056 Lifetime PVD Satin Nickel, 112 Venetian Bronze, and 190 Satin Black. The two PVD finishes are the ones to match on an exposed exterior patio door if you are trying to keep a set of doors looking the same over time. The trim is brass under the finish.

It is Estate Series with traditional-design trim, so it is the family that matches other Estate levers, knobs, and entry sets rather than the lighter Reserve or Prestige lines. Match on finish code, not just on name: order the 8231 in the same code (003, 056, 112, or 190) as the hardware already hanging.

No. The Estate 8231 is reversible, so one part number serves left and right hand openings and there is nothing to specify at order. That is worth knowing when you are cross-shopping - the reversible construction and the adjustable 2-3/8 inch or 2-3/4 inch backset together mean a single SKU covers a mixed set of doors. Peers such as the Accentra D111 are built to a fixed 2-3/8 inch backset, so the prep has to be confirmed door by door.
