Weslock 0771 Square Single Cylinder Deadbolt with Adjustable Latch and Round Corner Full Lip Strike

The 0771 ships with an adjustable latch that sets to either 2-3/8 or 2-3/4 inch backset, which are the two standard bore positions, so you don't have to know the backset before you order. The cross bore is 2-1/8 inches, the normal residential deadbolt prep, and the latch face is 1 x 2-1/4 inches with a radius (round corner) faceplate.

If the door is already prepped with a 2-1/8 inch cross bore at a 2-3/8 or 2-3/4 inch backset, the 0771 goes straight in. The jamb is the part to check: it comes with a round corner full lip strike and a radius latch faceplate. If your old bolt used a square corner strike or a flat T-strike, you'll be chiseling the corners of the jamb mortise round, or reusing the existing strike if the bolt lines up.

Yes. Keyed alike is a free option on the 0771, alongside the standard keyed different, and there's a key code field if you need them cut to an existing code. The cylinder is a 5 pin on the Weslock keyway, so all the units you key together have to be Weslock keyway product. If your building is standardized on a Schlage C keyway, this is the wrong bolt for that job.

Residential. The 0771 is built to exceed ANSI Grade 3 lock standards, which is the residential tier, and it's catalogued for residential use. For a commercial opening or a high-turnover multifamily entry, step up to a Grade 2 or Grade 1 bolt: the Hager 3215 is a Grade 2 commercial single cylinder with a 1 inch throw, and the Delaney LM Series and Dexter DB1000 are Grade 1 single cylinder options.

No. The 0771 tops out at 1-3/4 inches. For a thicker slab, the Deltana 7312KA2 covers 1-3/8 to 2 inches, and the Corbin Russwin DL3011 cylindrical deadlock runs 1-3/4 to 2-1/4 inches. The Dexter DB1000 goes to 1-7/8 inches if you're only slightly over.

No. The Weslock 0771 is a residential cylinder x thumbturn deadbolt, which locks from inside by turning the thumbturn. Classroom-function deadbolts include the Falcon D111, a Grade 1 heavy duty classroom deadbolt with an adjustable backset, and the Falcon D211, a Grade 2 classroom function deadbolt with single cylinder operation. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder covering 1-3/8 to 1-3/4 inch doors, the same door thickness the 0771 adjusts to.

The Weslock 0771 is a square-trim single cylinder deadbolt in cylinder x thumbturn function with a 2-1/2 inch square rosette. The Bravura 310SC Elite is the nearest square-faced counterpart, a Grade 2 contemporary square deadbolt in the same cylinder x thumbturn function. The Callan Model 200S is another square-trim option, a Grade 3 single cylinder square trim deadbolt, also cylinder x thumbturn. The Brinks Mendocino Series E2402 is a contemporary square single cylinder deadbolt with a 4-way adjustable backset, which matches the Weslock 0771's 2-3/8 or 2-3/4 inch backset coverage. All three keep the square exterior look with a keyed outside and thumbturn inside.

The Weslock 0771 is a residential deadbolt built to exceed ANSI Grade 3. When a spec calls for Grade 1, the Dexter DB1000 single cylinder deadbolt is a Grade 1 cylinder x thumbturn unit covering 1-3/8 to 1-7/8 inch doors, which spans the 1-3/8 to 1-3/4 inch range the Weslock 0771 adjusts to. The Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset and a 1-3/8 to 1-3/4 inch door thickness range. The Deltana CL200LM and the Delaney LM Series are also Grade 1 single cylinder deadbolts in cylinder x thumbturn. For a commercial opening with a fire-rated latch, the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.

The Weslock 0771 is keyed outside with a thumbturn inside, so it is not the right choice where a double cylinder is required. Double cylinder equivalents include the Callan Model 210S, a Grade 3 double cylinder deadbolt, and the Delaney LU Series, a Grade 2 double cylinder deadbolt. The Dexter DB2000 double cylinder is Grade 2 and covers 1-3/8 to 1-3/4 inch doors, matching the door thickness range the Weslock 0771 adjusts to; the Dexter DB1000 double cylinder is the Grade 1 version and covers 1-3/8 to 1-7/8 inch. In a square contemporary look, the Baldwin Reserve Double Cylinder Contemporary Square Deadbolt keeps the square face while removing the thumbturn.

The Weslock 0771 uses a 5 pin cylinder on the Weslock keyway, so it keys into a Weslock master system rather than a Schlage one. If the building is already keyed Schlage C, the Hager 3215 is a single cylinder deadbolt with a 1 inch throw on the Schlage C keyway, Grade 2, covering 1-3/8 to 1-3/4 inch doors. The Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt on the Schlage C keyway over the same door thickness range, and the Hager 3118 is the Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder. For a small-format interchangeable core opening, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep supplied less core, and the Deltana CL200LAIC is a Grade 2 interchangeable core single deadbolt with a 2-3/4 inch backset.

Several. The Weslock 0771 is a bored deadbolt with a 2-1/8 inch cross bore and a 1 inch by 2-1/4 inch latch faceplate. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, so they need a mortise pocket, not a bored hole. The Dormakaba D900 is a small case mortise deadbolt and the Codelocks CL2210 is an electronic mortise deadbolt, both mortise-prepped. The Codelocks CL200 with key override and the CL2200 electronic deadbolt are surface deadbolts that mount on the face of the door. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock but is cylinder x blank with a 1-3/4 to 2-1/4 inch door thickness range, so it has no thumbturn and expects a thicker door than the 0771's 1-3/8 to 1-3/4 inch. The Arrow 460 is a mortise lock strike, hardware for the frame rather than a lock for the door.

The Weslock 0771 adjusts to door thickness from 1-3/8 to 1-3/4 inch, so a thicker slab is outside its range. The Deltana 7312KA2 is a Grade 3 heavy duty double cylinder deadbolt covering 1-3/8 to 2 inch. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 to 2-1/4 inch, though it is cylinder x blank rather than cylinder x thumbturn. If the door is closer to 1-7/8 inch and you want to keep the thumbturn inside, the Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn covering 1-3/8 to 1-7/8 inch.

Single cylinder: key outside, thumbturn inside. That's the right choice for a door with no glass near the lock, since anyone reaching through can't turn the bolt from outside. On a door with sidelites or glass within arm's reach of the lock, a double cylinder bolt (keyed both sides) is what people use instead, like the Bravura or Callan double cylinder deadbolts, though a key-both-sides bolt has egress implications you should confirm against your local code.

The 0771 uses a 2-1/2 inch square rosette with 3/4 inch projection on the exterior and 1-1/4 inch projection on the interior. That exterior number matters on a storm door or a screen door hung close to the slab, and on a door where a wreath, hanger, or gate swing passes the lock. The interior projection is the thumbturn side.

No. The 0771 has square trim, a 2-1/2 inch square rosette. Set beside a round rosette lock it reads as a different design, not a match. If the rest of the building is round, look at a round-trim bolt like the Bravura 310RC Elite or the Brinks Raleigh Series. If you're standardizing on square, the Bravura 310SC Elite and Callan 200S are square-trim single cylinder deadbolts too.

Everything for the door and jamb is in the box: the adjustable latch with the radius faceplate, the round corner full lip strike, and the cross cam deadbolt cam and sit-in-style cylinder that make it a straightforward install. Screws are concealed on the finished trim. You supply nothing beyond a prepped door, a 2-1/8 inch cross bore, and 2-3/8 or 2-3/4 inch backset.

The Weslock 0771 is a bored deadbolt using a 2-1/8 inch cross bore with a 2-3/8 or 2-3/4 inch backset. Grade 2 bored deadbolts that install the same way include the Arrow DBX61 single cylinder deadbolt, the Bravura 310B Elite traditional round deadbolt, the Bravura 310RC Elite contemporary round deadbolt, and the Cal-Royal CB160, which adds a tamper-resistant cylinder guard. The Dexter DB2000 single cylinder is Grade 2 in cylinder x thumbturn and covers 1-3/8 to 1-3/4 inch doors, the same door thickness the Weslock 0771 adjusts to. All are cylinder x thumbturn, so the outside stays keyed and the inside stays a turn.

Yes. The Weslock 0771 adjusts to a 2-3/8 or 2-3/4 inch backset and to door thickness from 1-3/8 to 1-3/4 inch. The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset covering 1-3/8 to 1-3/4 inch doors, the same thickness range. The Cal-Royal LSD is also Grade 3 cylinder x thumbturn over 1-3/8 to 1-3/4 inch and carries an ADA ergonomic thumbturn, which matters on doors where the interior turn has to be operable without tight grasping. The Brinks Raleigh Series E2401 is a transitional round single cylinder deadbolt with a 4 way adjustable backset if the round rosette suits the door better than the 0771 square trim.

The Weslock 0771 is a single cylinder deadbolt, keyed outside with a thumbturn inside, so it is not a fit where nothing should be keyed. The Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate on the outside and a thumbturn on the inside, covering 1-3/8 to 1-3/4 inch doors, which is the same door thickness range the 0771 adjusts to. For an opening that is only bored on one face, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt.

The Weslock 0771 is a mechanical single cylinder deadbolt on a 5 pin Weslock keyway, so every tenant change means a rekey or a new key. Keypad and credential alternatives include the Delaney KP400, a Grade 2 electronic deadbolt with a programmable remote; the Codelocks CL2200, a medium duty electronic surface deadbolt; the Dormakaba Saffire LX-D, an RFID electronic deadbolt with BLE and electronic lock override; and the Dormakaba Nova-D, an RFID multihousing smart electronic deadbolt built for multi-family. Note these are electronic-function locks rather than bored mechanical deadbolts, so confirm the door prep before you standardize.

The Weslock 0771 is a standalone deadbolt with no latching function, so it is normally paired with a separate knob or lever. The Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt built in, so one device covers both the latch and the bolt on a multi-family entry. The Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in entrance function if the design intent is a decorative bolt on a high-end unit rather than an interconnected set.

The Weslock 0771 ships as a complete single cylinder deadbolt with an adjustable latch and a round corner full lip strike. Some similarly named items are not complete locks: the BEST 8T is a T Series tubular deadbolt tube component, the Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, and the Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip. The Arrow E61 26D IC is a complete deadlock but is supplied less core, so a small format interchangeable core has to be ordered with it.

Five: oil rubbed bronze, matte black, satin brass, bright chrome, and satin nickel. That covers the usual pairing jobs, matte black or oil rubbed bronze against dark exterior trim, satin nickel or bright chrome against the more common builder-grade knob and lever sets.

The 0771 body is zinc alloy, which is the standard casting for residential deadbolt trim, and it's built to exceed ANSI Grade 3 residential lock standards. For a single-family or low-traffic exterior entry that's the normal spec. On a door cycled dozens of times a day, a heavier bolt is the better buy.
