Dexter DB1000 Series - Grade 1 Double Cylinder Deadbolt

Yes. With the standard conventional cylinder the DB1000 covers 1-3/8 inch through 1-7/8 inch doors, so a 1-3/4 inch commercial door sits comfortably in range. If you order the SFIC prep version instead, the range shifts up to 1-5/8 inch through 2 inches, which still covers 1-3/4 but rules out thin 1-3/8 inch interior doors. Pick the conventional cylinder for older 1-3/8 inch leaves.

A double cylinder deadbolt is keyed on both sides, so there is no thumbturn inside. The Dexter DB1000 in the double cylinder function is used where a glass sidelight or lite means an inside thumbturn could be reached and flipped from outside. The tradeoff is that nobody leaves without a key, which is why many jurisdictions restrict double cylinder on a required egress door. If the opening needs free egress, order a cylinder x thumbturn instead: the Accentra D111 and the Cal-Royal CRB800 are both single cylinder Grade 1 deadbolts with a thumbturn inside.

Yes, if your building keys on Schlage C. The DB1000 takes a Schlage C keyway conventional 6-pin cylinder, shipped keyed different, so a locksmith can key it into an existing Schlage C system. For a facility running small format interchangeable core, order the SFIC prep less core version and drop your own cores in both sides.

Both are included. Every function ships with a 2-3/8 by 2-3/4 inch universal square corner latch, part number 30-253, and a 1-1/8 by 2-3/4 inch square corner lipless strike. The universal latch is what lets the same bolt serve either the 2-3/8 or 2-3/4 inch backset, the two standard bores you will find in an existing door.

In most cases yes on a standard tubular deadbolt prep. The universal latch covers both the 2-3/8 and 2-3/4 inch backset, so you do not have to know which one was bored. The frame side is the thing to check: the included strike is a 1-1/8 by 2-3/4 inch square corner lipless strike, so if your frame is mortised for a radius corner strike or a lipped strike you will need to re-prep the frame or reuse the existing strike.

The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt supplied with a UL 3-hour fire rated latch. The Hager 3118 is a Grade 1 cylinder by thumbturn deadbolt with a fire rating, for 1-3/8 inch to 1-3/4 inch doors. Both are cylinder by thumbturn rather than keyed both sides, so on a fire-rated opening you are also changing the inside function away from the Dexter DB1000's double cylinder.

The Corbin Russwin DL3011 cylindrical deadlock is a Grade 1 deadbolt built for doors 1-3/4 inch to 2-1/4 inch. The Dexter DB1000 tops out at 1-7/8 inch with the conventional cylinder and 2 inch in SFIC form, so on a 2-1/4 inch door the DL3011 is the one that fits.

Go to a thumbturn or non-keyed inside instead. The Falcon D111 is a Grade 1 heavy duty deadbolt with cylinder by thumbturn and an adjustable backset. The Hager 3118 is a Grade 1 cylinder by thumbturn deadbolt in Schlage C with a 6-pin cylinder, fitting 1-3/8 inch to 1-3/4 inch doors and fire rated. For no key at all, the Arrow E60 is a Grade 2 exit deadlock, blank plate by thumbturn, for 1-3/8 inch to 1-3/4 inch doors. The Dexter DB1000 is keyed on both sides.

The Design Hardware D1 Series is the nearest match. It is a Grade 1 double cylinder deadbolt rated extra heavy duty, keyed on both sides like the DB1000, and it is built for a 1-3/4 inch door. The DB1000 spans a wider opening range at 1-3/8 inch to 1-7/8 inch for the conventional cylinder, so on a 1-3/8 inch or 1-7/8 inch door the Dexter covers thicknesses the D1 does not.

Yes. The Hager 3214 is a Grade 2 double cylinder deadbolt in the Schlage C keyway, fitting doors 1-3/8 inch to 1-3/4 inch, and it carries a fire rating. The Delaney LU Series 320601 is another Grade 2 double cylinder, supplied in stainless steel US32D. The Dexter DB1000 is the Grade 1 option of the three and takes Schlage C 6-pin conventional cylinders as well as SFIC.

The Arrow E61 is a Grade 2 single cylinder deadlock prepped for SFIC less core, for 1-3/8 inch to 1-3/4 inch doors. The Deltana CL200LAIC is a Grade 2 single cylinder deadbolt supplied for an interchangeable core with no cylinder, on a 2-3/4 inch backset. The Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D. The Dexter DB1000 is the double cylinder SFIC prep option and takes a 1-5/8 inch to 2 inch door in SFIC form.

Two choices, four combinations total. Cylinder: KDC conventional 6-pin Schlage C keyed different, or SFIC prep less core if you supply your own cores. Finish: 626 satin chrome (US26D) or 613 oil rubbed bronze (US10B). Both cylinder options are offered in both finishes. Note the cylinder choice also changes the door thickness range, so settle the door first.

For a door that gets daily commercial traffic or an entry you expect to be attacked, Grade 1 is the ANSI/BHMA top tier and the DB1000 meets it. Grade 2 is the step down and is common on lighter multifamily work. If budget pushes you there, the Hager 3214 is a Grade 2 double cylinder that also uses a Schlage C keyway, and the Delaney LU Series is a Grade 2 double cylinder in US32D stainless. If you want to stay Grade 1 and double keyed, the Design Hardware D1 Series is the direct equivalent, though it is a 1-3/4 inch door only device.

The DB1000 comes in 626 satin chrome (US26D) and 613 oil rubbed bronze (US10B), the two finishes most commercial openings are already running, and it ships in master cartons of 8 for every UPC, which is the quantity to think in for a fleet order. Key the whole run on Schlage C conventional cylinders, or spec the SFIC prep and put your own cores in so you keep one core inventory across the property.

The SFIC prep version ships less core: it is machined for small format interchangeable cores that you supply and install, which is how facilities rekey in seconds without pulling the lock. The conventional version arrives complete with a 6-pin Schlage C cylinder, keyed different. Two practical consequences: the SFIC version needs your core inventory on hand before it can be locked, and its door range starts at 1-5/8 inches rather than 1-3/8, so it will not serve a thin older door.

They share the double cylinder function, but the Baldwin Reserve round and square Contemporary deadbolts are decorative trim products, and the Baldwin Estates 8011 Contemporary is a 1-5/8 inch double cylinder in the Estate Series. The Dexter DB1000 is a Grade 1 commercial deadbolt that accepts Schlage C 6-pin conventional or SFIC cylinders. If the opening is spec'd to an ANSI grade, the Baldwin double cylinders are not carrying that grade in their place.

No. The Baldwin Reserve 8BR0618001 is a spacer for a double cylinder deadbolt, a filler part rather than a working lock. The Dexter DB1000 is the deadbolt itself, Grade 1, keyed both sides, and shipped with a 2-3/8 inch by 2-3/4 inch universal square corner latch (p/n 30-253) and a 1-1/8 inch by 2-3/4 inch square corner strike. The BEST 8T tube component is similar in kind, a deadbolt tube part rather than a complete lock.

The Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the CL2210 is an electronic mortise deadbolt. The Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. All change the credential; the Dexter DB1000 stays mechanical on a Schlage C 6-pin or SFIC cylinder.

The Accentra D111 is a Grade 1 single cylinder deadbolt, cylinder by thumbturn, on a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch. The Deltana CL200LM is a Grade 1 single cylinder deadbolt, also cylinder by thumbturn. Both give a thumbturn inside where the Dexter DB1000 takes a key on both faces.

A mortise deadlock is the right family there. The International Door Closers DH-1821 is a hook bolt deadlock with a flat faceplate, and the DT-1851 is a long throw deadlatch lock with a flat faceplate. The Dormakaba D900 is a small case mortise deadbolt, cylinder by turn, keyed different in SC keyways. The Dexter DB1000 is a bored deadbolt that needs a standard cross-bore and a 2-3/8 inch by 2-3/4 inch latch prep.

The Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset, and the Cal-Royal ED500 is a Grade 3 deadbolt with an adjustable backset for 1-3/8 inch to 1-3/4 inch doors. The Brinks E2401 Raleigh and E2402 Mendocino single cylinder deadbolts use a 4-way adjustable backset. The Dexter DB1000 ships with a universal 2-3/8 inch by 2-3/4 inch latch (p/n 30-253) covering both standard backsets.

The Corbin Russwin DL3211 and DL2211 are Grade 1 cylindrical deadlocks, cylinder by blank plate, for 1-3/4 inch doors. That gives a keyed outside and a flat plate inside with no operating trim. The Dexter DB1000 is keyed on both faces instead.

No. The Arrow 460 is a mortise lock strike for latchbolt by deadbolt functions with a straight lip, sized for mortise lock prep. The Dexter DB1000 uses a 1-1/8 inch by 2-3/4 inch square corner lipless strike, which is a different frame cutout entirely.
