Sure-Loc DB201-FR 15 – Frequently Asked Questions

1) Will the Sure-Loc Forma DB201 deadbolt fit a 1-3/8 inch door?
No. The Forma DB201 covers doors 1-3/4 inch to 2-1/4 inch (45-55mm) thick, so a standard 1-3/8 inch interior door is below its range. For thinner doors look at a deadbolt that starts at 1-3/8 inch, such as the Dexter DB2000 single cylinder (1-3/8 inch to 1-3/4 inch) or the Cal-Royal ED500.
2) Does the Forma DB201 deadbolt work with a 2-3/8 or a 2-3/4 inch backset bore?
Both. The DB201 backset is adjustable and specified as 2-3/8 inch or 2-3/4 inch (60-70mm), which are the two standard residential bore positions, so it drops into existing prep either way.
3) Can I key the Sure-Loc Forma deadbolt to match my existing Kwikset or Schlage keys?
The Forma DB201 cylinder uses the KW1 keyway, which is the Kwikset profile, and SC1 (the Schlage profile) is also available. That lets you bring it onto an existing residential key system rather than carrying a second key.
4) Is this a single cylinder deadbolt with a thumbturn inside, or keyed both sides?
Single cylinder: key outside, thumbturn inside. If you need a key on both sides for a door with glass beside it, a double cylinder unit such as the Callan 210S or the Dexter DB2000 double cylinder is the one to order instead. Keep in mind double cylinder deadbolts are restricted on egress doors in many jurisdictions.
5) Is the Sure-Loc Forma DB201 suitable for a commercial or institutional opening?
It is built and catalogued as residential hardware, aimed at entry doors on houses, rentals, and multi-family units. For a commercial opening where a spec calls out an ANSI grade, choose from the graded options instead, for example the Cal-Royal CB160 Grade 2 or the Accentra D111 Grade 1.
6) What is a close equivalent to the Sure-Loc DB201 Forma single cylinder deadbolt from another brand?
The Sure-Loc DB201 Forma is a keyed tubular single cylinder deadbolt with a KW1 keyway (SC1 also available). Comparable cylinder x thumbturn single cylinder deadbolts include the Dexter DB2000-SCT, a Grade 2 single cylinder deadbolt for doors 1-3/8 inch to 1-3/4 inch thick, and the Bravura 310B Elite, a Grade 2 traditional round single cylinder deadbolt. Both operate the same way - key outside, thumbturn inside - so the choice comes down to trim style, finish, and the door thickness you are working with.
7) I need a deadbolt for a 2 inch thick door - does the Sure-Loc Forma work, or do I need something else?
Yes. The Sure-Loc DB201 Forma fits doors 1-3/4 inch to 2-1/4 inch thick, so a 2 inch door is inside its range. Most comparable residential and commercial deadbolts stop short of that: the Dexter DB2000-SCT covers 1-3/8 inch to 1-3/4 inch, the Hager 3215 covers 1-3/8 inch to 1-3/4 inch, and the Cal-Royal ED500 covers 1-3/8 inch to 1-3/4 inch. If you want an alternative that also reaches past 1-3/4 inch, the Corbin Russwin DL3011 cylindrical deadlock is rated for 1-3/4 inch to 2-1/4 inch doors.
8) My door has glass next to it - is the Sure-Loc Forma the right choice or do I need a double cylinder?
The Sure-Loc DB201 Forma is a single cylinder deadbolt, meaning it is keyed outside with a thumbturn inside. Where glass sidelites or a glass panel let someone reach the thumbturn, a double cylinder that requires a key on both sides is the usual call. Double cylinder options include the Dexter DB2000-DCT for doors 1-3/8 inch to 1-3/4 inch thick, the Callan Model 210S Grade 3 double cylinder deadbolt, and the Hager 3214 Grade 2 double cylinder for 1-3/8 inch to 1-3/4 inch doors. Confirm your local egress code before specifying double cylinder on an exit door.
9) I need small format interchangeable core on my deadbolts - is the Sure-Loc Forma an option?
The Sure-Loc DB201 Forma ships as a keyed tubular deadbolt on a KW1 keyway profile, not an interchangeable core prep. If your facility keys on SFIC or IC cores, look instead at the Arrow E61 Grade 2 single cylinder deadlock supplied with SFIC prep less core for doors 1-3/8 inch to 1-3/4 inch thick, the Deltana CL200LAIC Grade 2 interchangeable core deadbolt with a 2-3/4 inch backset, or the Delaney LM Series Grade 1 single cylinder less core deadbolt in dull chrome US26D.
10) How secure is the bolt on the Sure-Loc Forma deadbolt against sawing?
The bolt carries hardened steel rolling inserts, which spin under a blade and resist cutting or sawing. The housing itself is solid brass. It's residential-duty security, not a graded commercial deadbolt.
11) I'm standardizing deadbolts across a rental portfolio. Can I put the same Forma deadbolt on every unit door?
Yes, provided the doors are 1-3/4 to 2-1/4 inch thick. With a 2-3/8 or 2-3/4 inch adjustable backset, one part number covers both common bore positions, and a single keyway (KW1, or SC1) across the portfolio keeps the key system consistent. Pick one of the four finishes and it repeats the same across every opening.
12) What else in the same thickness range as the Forma DB201 could I use on a thicker door?
The Corbin Russwin DL3011 cylindrical deadlock also covers 1-3/4 inch to 2-1/4 inch doors, so it's the option when the opening is thick and the spec calls for Grade 1 commercial hardware rather than residential trim.
13) Is the BEST 8T tubular deadbolt a substitute for the Sure-Loc Forma DB201?
No. The Sure-Loc DB201 Forma is a complete single cylinder tubular deadbolt with solid brass housing, trim, and a cut-resistant bolt. The BEST 8T is a T Series tubular deadbolt tube component - the bolt assembly on its own, not a finished lock with trim and cylinder. In the same vein, the Baldwin Reserve 8BR0618001 is a deadbolt spacer and the Arrow 460 is a mortise lock strike, both accessories rather than deadbolts.
14) What deadbolt should I use on a classroom door instead of the Sure-Loc Forma?
The Sure-Loc DB201 Forma is a residential single cylinder deadbolt. Classroom-function deadbolts are a different animal: the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, the Falcon D211 is the Grade 2 medium duty classroom-function version with single cylinder operation, and the Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in classroom function, cylinder x blank, for 1-3/4 inch doors.
15) My building is keyed on Schlage keys - can I use the Sure-Loc Forma or should I pick a different deadbolt?
The Sure-Loc DB201 Forma uses a KW1 keyway with SC1 also available, so it can be specified to run on a Schlage-profile key system. If you would rather buy a deadbolt built around the Schlage C keyway from the start, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder.
16) I want a keyless or electronic version instead of the keyed Sure-Loc Forma - what are my options?
The Sure-Loc DB201 Forma is a keyed mechanical deadbolt with no electronic components. For keyless operation, the Codelocks CL200 is a surface deadbolt with key override, and 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 thick. For electronic, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote and the Codelocks CL2200 is an electronic surface deadbolt in brushed steel.
17) Is there a square-trim deadbolt alternative to the round Sure-Loc Forma for a modern entry?
The Sure-Loc DB201 Forma comes in satin nickel, polished chrome, flat black, and satin brass. If you want square or contemporary trim to match a modern entry, the Bravura 310SC Elite is a Grade 2 contemporary square single cylinder deadbolt, the Callan Model 200S is a Grade 3 single cylinder square trim deadbolt, and the Brinks Mendocino Series is a contemporary square single cylinder deadbolt with a 4 way adjustable backset. All three are cylinder x thumbturn like the Forma.
18) I have a door with no interior bore prepped - can I still use the Sure-Loc Forma?
The Sure-Loc DB201 Forma is a tubular deadbolt that needs a full cross bore through the door for the cylinder outside and thumbturn inside. If the door is only prepped on one face, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt built for that condition. For a surface-applied option that does not rely on a cross bore at all, the Codelocks CL200 is a surface deadbolt with key override.
19) I need a deadbolt with a thumbturn that is easier to grip for ADA - is the Sure-Loc Forma that, or is there a better pick?
The Sure-Loc DB201 Forma is a standard single cylinder deadbolt with a conventional thumbturn. If ergonomic operation is the driver, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt built with an ADA ergonomic thumbturn, sized for doors 1-3/8 inch to 1-3/4 inch thick.
20) Does the Sure-Loc Forma work as a European mortise deadbolt replacement?
No. The Sure-Loc DB201 Forma is a tubular deadbolt that installs into a standard bored door prep with a 2-3/8 inch or 2-3/4 inch backset. A door prepped for a European mortise case needs a mortise body: the Emtek 2050 is a European mortise deadbolt with integrated roller latch in square trim and the Emtek 2051 is the round trim version, both cylinder x thumbturn. The Dormakaba D900 is a small case mortise deadbolt, cylinder x thumbturn, keyed different on SC keyways.
21) I want a Grade 1 deadbolt instead of the Sure-Loc Forma for a rental turnover - what are the equivalents?
The Sure-Loc DB201 Forma is a residential tubular single cylinder deadbolt. If your spec calls for Grade 1 on the same cylinder x thumbturn function, the Dexter DB1000-SCT is a Grade 1 single cylinder deadbolt for doors 1-3/8 inch to 1-7/8 inch thick, the Deltana CL200LM is a Grade 1 single cylinder deadbolt, and the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt with a 2-3/8 inch backset.
22) What finishes does the Sure-Loc Forma single cylinder deadbolt come in?
Four: 15 Satin Nickel, 26 Polished Chrome, FBL Flat Black, and SB Satin Brass. Satin Nickel and Satin Brass are the usual matches for older residential trim; Flat Black suits current black hardware packages across a unit turnover.
23) Is the Sure-Loc Forma deadbolt electronic or keypad operated?
No, it's a mechanical key deadbolt with no electronics. If you want code or credential entry on that opening, the Delaney KP400 electronic deadbolt or the Codelocks CL2200 surface deadbolt are the electronic routes.
24) How does the Sure-Loc Forma compare to a solid bronze or cast deadbolt for a high-end entry?
The Sure-Loc DB201 Forma pairs a solid brass housing with a cut-resistant bolt using hardened steel rolling inserts, offered in satin nickel, polished chrome, flat black, and satin brass. If you are specifying a decorative entry, the Emtek #11 Tuscany is a lost wax cast bronze cylinder x thumbturn deadbolt and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in entrance function. The Emtek matches the Forma's single cylinder key-outside thumbturn-inside operation; the Baldwin 8011 is keyed both sides.
