Weslock 0667 Turn Only Deadbolt with Adjustable Latch and Deadbolt Strike

That's exactly what the 0667 is built for. It's a one-sided turn only deadbolt, so the thumbturn side is the only side that operates it and the outside face gets no cylinder. Common uses are interior doors, storage and utility rooms, garage-to-house doors, and any opening where you want to throw a bolt from inside but never need to unlock it from outside. If someone on the other side needs key access, this is the wrong part and you want a single cylinder deadbolt instead.

Both. The 0667 ships with an adjustable latch that sets to either 2-3/8 or 2-3/4 inches, which are the two standard residential backsets, so you measure from the door edge to the center of the bore and set the latch to match. You don't have to know the backset before you order.

The 0667 uses a 2-1/8 inch cross bore, the standard bore for residential deadbolts, and the latch faceplate mortises into a 1 by 2-1/4 inch pocket in the door edge. If you're replacing an existing deadbolt that was bored to those dimensions, the prep is already there and no new drilling is needed.

Weslock lists the 0667 as residential hardware, Traditionale collection, so it suits houses and light residential openings rather than commercial traffic. For a commercial entrance or a high-traffic multi-family door, look at a graded deadbolt instead: the Accentra D111 and the Delaney LM Series are Grade 1 single cylinder units, and the Arrow DBX61 or Cal-Royal CB160 are Grade 2.

Both are one-sided deadbolts operated by a thumbturn with no exterior keyed cylinder. The Weslock 0667 is a Traditionale series residential deadbolt with a 2-3/4 inch diameter turn and 7/8 inch projection, a 1 inch by 2-1/4 inch latch faceplate, and a 2-3/8 or 2-3/4 inch backset. The Callan 205S is a Grade 3 half-bore deadbolt, meaning the door is prepped on the inside face only. Both suit an opening where you want the door bolted from inside and nothing on the exterior face.

A turn only deadbolt has no exterior cylinder, so an opening that must be locked and unlocked from outside needs a single cylinder unit instead. The Dexter DB2000 single cylinder is a Grade 2 cylinder by thumbturn deadbolt for doors 1-3/8 to 1-3/4 inch thick, and the Dexter DB1000 single cylinder is the Grade 1 equivalent for doors 1-3/8 to 1-7/8 inch. Both keep a thumbturn on the inside face while adding a key on the outside.

The 0667 is a residential Traditionale deadbolt. For a commercial opening carrying a graded spec, the Cal-Royal CRB800 is a heavy duty Grade 1 single cylinder deadbolt with a UL 3-hour fire rated latch, the Hager 3215 is a Grade 2 single cylinder with a 1 inch throw for doors 1-3/8 to 1-3/4 inch, and the Design Hardware D1 Series is an extra heavy duty Grade 1 double cylinder for 1-3/4 inch doors.

The escutcheon measures 2-3/4 inches in diameter with a 7/8 inch projection. That matters where the door swings tight to a wall or where a storm door, screen door, or cabinet sits close to the face, and the 2-3/4 inch round trim also tells you how much of the old finish ring it will cover if you're swapping out a previous bolt.

The deadbolt strike is included along with the adjustable latch, so the door edge and the jamb are both covered in the box. What is not included is anything for a jamb that's chewed up or out of alignment, which is the usual reason a bolt won't throw fully after a swap.

Three different answers to the same opening. A one-sided turn only bolt like the Weslock 0667 has no outside cylinder at all, so nobody enters through it, keyed or not. A double cylinder needs a key on both faces, which is what people put on glass-adjacent doors so an arm through a broken pane can't turn a thumbturn; the Callan 210S and the Delaney LU Series are double cylinder units. A single cylinder gives you key outside, turn inside, which is the normal entry-door setup. Check your local egress code before putting a double cylinder on a required exit door.

The Weslock 0667 is a turn only, one-sided bolt on a 2-1/8 inch cross bore. If your door is already bored partway or you want a half-bore prep, the Callan 205S is a one-sided half-bore deadbolt. Both give you a thumbturn inside and a blank outside; the difference is how much of the door you have to drill through.

It works as a thumbturn-from-inside bolt, but understand the tradeoff: with no outside cylinder, anyone who pulls that door shut behind them is locked out until someone opens it from inside. For a non-keyed exit deadlock built for that duty, the Arrow E60 is a Grade 2 blank plate by thumbturn deadlock for 1-3/8 to 1-3/4 inch doors.

A double cylinder deadbolt keys both faces and eliminates the thumbturn entirely, the opposite arrangement from the Weslock 0667 turn only. The Callan 210S is a Grade 3 double cylinder, the Delaney LU Series 320601 is a Grade 2 double cylinder in stainless steel US32D, and the Deltana 7312KA2 is a Grade 3 double cylinder for doors 1-3/8 to 2 inch thick. Verify local egress code before specifying a double cylinder on a required exit door.

The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 to 1-3/4 inch thick. The Weslock 0667 uses a 2-3/4 inch diameter turn with a 7/8 inch projection. Where a facility is standardizing on ergonomic turn hardware, the LSD carries the ADA thumbturn but also carries an exterior keyed cylinder, which the turn only 0667 does not.

The 0667 is a turn only deadbolt with no exterior cylinder to core. For a small format interchangeable core opening, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for doors 1-3/8 to 1-3/4 inch, and the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt with an interchangeable core prep on a 2-3/4 inch backset.

No. The Baldwin 8BR0618001 is a spacer component for a Reserve double cylinder deadbolt, not a working lock. The Weslock 0667 is a complete turn only deadbolt with an adjustable latch on a 2-3/8 or 2-3/4 inch backset and a deadbolt strike. The same caution applies to the BEST 8T tube component, which is the tubular deadbolt tube for a T Series assembly rather than a finished deadbolt.

The Weslock 0667 covers 2-3/8 or 2-3/4 inch backsets on a 2-1/8 inch cross bore. For the same backset flexibility with an exterior key, the Brinks Raleigh E2401 is a transitional round single cylinder deadbolt with a 4 way adjustable backset, the Brinks Mendocino E2402 is the contemporary square version, and the Cal-Royal ED500 is a Grade 3 single cylinder with adjustable backset for doors 1-3/8 to 1-3/4 inch.

Not directly. The 0667 is a bored deadbolt installed through a 2-1/8 inch cross bore with a 1 inch by 2-1/4 inch latch faceplate. Mortise units such as the Emtek 2050 European mortise deadbolt with integrated roller latch, the Dormakaba D900 small case mortise deadbolt, and the Codelocks CL2210 electronic mortise deadbolt all require a mortise pocket routed into the door edge, which is a different door prep entirely.

Classroom function deadbolts key the exterior and are graded for institutional traffic, unlike the residential turn only 0667. The Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, the Falcon D211 is the Grade 2 medium duty classroom version, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for doors 1-3/8 to 1-3/4 inch.

Brass substrate, offered in Antique Brass. If you're matching other Traditionale hardware on the same door or across a house, the brass body and antique brass finish are what to compare against the knobs and levers already hung.

The Weslock 0667 is a mechanical turn only deadbolt. For credential-based operation on the same door, 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 Nova-D is an RFID multihousing smart electronic deadbolt for multi-family use.
