Sure-Loc DB301 26D – Frequently Asked Questions

1) Will the Sure-Loc Grade 2 single cylinder deadbolt fit a 1-3/8 inch door, or only a 1-3/4?
Both. The Sure-Loc Grade 2 single cylinder deadbolt fits doors 1-3/8 to 1-3/4 inches thick (35-45mm), which covers the standard 1-3/4 inch commercial door as well as older 1-3/8 inch interior doors. Thicker doors than 1-3/4 need a different bolt.
2) Does the Sure-Loc commercial deadbolt work with a 2-3/8 or 2-3/4 inch backset bore?
Either one. The backset is specified as 2-3/8 or 2-3/4 inches (60-70mm), and Sure-Loc bored locks are made to fit standard door prep with an adjustable backset, so it drops into whichever of the two crossbore centers your door already has.
3) Can I key this Sure-Loc deadbolt to my existing Schlage keys?
It comes with a 6-pin SC1 keyway, which is the standard Schlage residential keyway, so it can be keyed into an existing SC1 system. Keying is selected at order time as either keyed different or keyed alike.
4) I need several units keyed the same across a building - can Sure-Loc do that?
Yes. Keying is a required selection on the Sure-Loc Grade 2 deadbolt: keyed alike if you want one key to run multiple doors, or keyed different if each unit gets its own key. Both use the 6-pin SC1 keyway.
5) What is a direct equivalent to the Sure-Loc Commercial Grade 2 single cylinder deadbolt from another brand?
The Sure-Loc commercial deadbolt is a Grade 2 cylinder x thumbturn deadbolt with a 6-pin SC1 cylinder. The closest equivalents by grade and function are the Hager 3115, a Grade 2 cylinder x thumbturn deadbolt with Schlage C keyway fitting doors 1-3/8 inch to 1-3/4 inch, and the Dexter DB2000-SCT, a Grade 2 single cylinder deadbolt with the same 1-3/8 inch to 1-3/4 inch door thickness range. The Arrow DBX61 and the Cal-Royal CB160 are also Grade 2 cylinder x thumbturn deadbolts, the Cal-Royal adding a tamper-resistant cylinder guard.
6) My facility keys everything on small format interchangeable core - what deadbolt do I order instead?
The Sure-Loc commercial deadbolt ships with a 6-pin SC1 cylinder, so it is not an SFIC part. For interchangeable core keying, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for doors 1-3/8 inch to 1-3/4 inch, and the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt with interchangeable core prep 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.
7) I need a heavier deadbolt than Grade 2 for a high-traffic entry - what should I specify instead?
For a heavier specification, step up to a Grade 1 single cylinder deadbolt. The Accentra D111 is Grade 1 cylinder x thumbturn with a 2-3/8 inch backset, fitting doors 1-3/8 inch to 1-3/4 inch. The Dexter DB1000-SCT is Grade 1 cylinder x thumbturn covering 1-3/8 inch to 1-7/8 inch doors. The Falcon D111 is a Grade 1 heavy duty deadbolt with adjustable backset, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Sure-Loc unit remains the Grade 2 choice with its 6-pin SC1 keyway.
8) What do I use if the door needs a key on both sides instead of a thumbturn?
The Sure-Loc commercial deadbolt is cylinder x thumbturn, so it is keyed on one side only. For key-both-sides openings, the Hager 3214 is a Grade 2 double cylinder deadbolt with Schlage C keyway fitting 1-3/8 inch to 1-3/4 inch doors, the Dexter DB2000-DCT is a Grade 2 double cylinder over the same door range, and the Delaney LU Series 320601 is a Grade 2 double cylinder deadbolt. For Grade 1, the Design Hardware D1 Series is an extra heavy duty double cylinder deadbolt for 1-3/4 inch doors.
9) Which deadbolts look like substitutes for a Grade 2 single cylinder bolt but will not work in the same prep?
Several parts carry deadbolt in the name without matching a standard bored cylinder x thumbturn prep. The Arrow 460 is a mortise lock strike, not a lock. The BEST 8T is a tubular deadbolt tube component rather than a complete lockset, and the Baldwin 8BR0618001 is a deadbolt spacer. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, which need a mortise pocket. The Codelocks CL200 is a surface mounted deadbolt with key override. The Sure-Loc unit is a keyed bored deadbolt in cylinder x thumbturn function.
10) What if my doors are thicker than 1-3/4 inches?
The Sure-Loc commercial deadbolt fits doors 1-3/8 inch to 1-3/4 inch thick. For thicker doors, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 inch to 2-1/4 inch. The Deltana 7312KA2 is a Grade 3 double cylinder deadbolt covering 1-3/8 inch to 2 inch, and the Dexter DB1000-SCT Grade 1 single cylinder reaches 1-7/8 inch.
11) The opening needs a fire rated deadbolt - which comparable carries a fire rating?
Among comparable Grade 2 single cylinder bolts, the Hager 3215 is a Grade 2 commercial deadbolt with a 1 inch throw carrying a fire rating and fitting doors 1-3/8 inch to 1-3/4 inch, and the Hager 3115 is a fire rated Grade 2 cylinder x thumbturn with Schlage C keyway over the same range. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch if the opening calls for Grade 1.
12) My openings are all Schlage keyed - which comparable deadbolts key into the same system?
The Sure-Loc commercial deadbolt uses a 6-pin SC1 keyway, which is the Schlage keyway. Comparables on the same keyway family include the Hager 3115 and Hager 3214, both Grade 2 with Schlage C keyway, and the Hager 3118, a Grade 1 classroom deadbolt with Schlage C keyway and 6-pin cylinder. The Dormakaba D900 small case mortise deadbolt is supplied keyed different with SC keyways.
13) Is this a single or double cylinder deadbolt, and does it have a key on both sides?
Single cylinder: key outside, thumbturn inside (cylinder x thumbturn). No key is needed to exit. If you need a keyed cylinder on both faces, for example on a door with glass beside it, look at a double cylinder unit such as the Dexter DB2000 double cylinder Grade 2.
14) Does the handing matter when I order this Sure-Loc deadbolt?
No handing to specify. Sure-Loc bored locks are reversible, so the same deadbolt works on a left or right hand door with no parts swap.
15) Is a Grade 2 deadbolt enough for an apartment entry door, or should I step up to Grade 1?
Grade 2 is the normal choice for multi-family and residential entry doors, and the Sure-Loc unit is a Grade 2 UL deadbolt with a brass build and stainless steel substrate. For higher-traffic or institutional openings, Grade 1 options in the same cylinder x thumbturn function include the Accentra D111 and the Dexter DB1000 single cylinder, and the Falcon D111 Grade 1 for classroom-style use.
16) Do I need to cut a new bore to install the Sure-Loc commercial deadbolt?
Not on a door already prepped for a standard bored deadbolt. It fits standard residential door preparation and adjusts to the 2-3/8 or 2-3/4 inch backset, so on a retrofit you are usually just pulling the old bolt and dropping this one in. A new door needs the standard deadbolt bore and edge prep.
17) Is there a keyless or electronic alternative to a keyed single cylinder deadbolt?
The Sure-Loc commercial deadbolt is mechanical and keyed, not electronic. If the opening should not be keyed at all, the Arrow E60 is a Grade 2 exit deadlock with a blank plate on the outside and thumbturn inside for doors 1-3/8 inch to 1-3/4 inch. For credential-based access, the Delaney KP400 is a Grade 2 electronic deadbolt with programmable remote, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override.
18) Is there a lighter duty deadbolt if Grade 2 is more than my apartment turns need?
Yes. The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for doors 1-3/8 inch to 1-3/4 inch, and the Cal-Royal LSD is Grade 3 with an ADA ergonomic thumbturn over the same door range. The Callan 200S is a Grade 3 single cylinder deadbolt with square trim. All are cylinder x thumbturn like the Sure-Loc commercial deadbolt, at a lower ANSI grade.
19) I need a classroom function deadbolt rather than a standard entry deadbolt - what are my options?
The Sure-Loc commercial deadbolt is a straight cylinder x thumbturn entry deadbolt. For classroom function, the Falcon D211 is a Grade 2 classroom deadbolt with single cylinder operation at medium duty, and the Falcon D111 is the Grade 1 heavy duty classroom version. The Hager 3118 is a Grade 1 classroom deadbolt with Schlage C keyway and 6-pin cylinder for doors 1-3/8 inch to 1-3/4 inch. Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in classroom function with a cylinder outside and blank plate inside for 1-3/4 inch doors.
20) Only the exterior side of the door can be bored - is there a deadbolt for that?
For a half-bore opening, the Callan 205S is a Grade 3 one-sided deadbolt that installs in a half bore. The Sure-Loc commercial deadbolt is a full cylinder x thumbturn bolt requiring the standard through-bore prep on both faces.
21) I want a squared or contemporary trim shape instead of a round deadbolt escutcheon - what matches on grade?
Staying at Grade 2 cylinder x thumbturn, the Bravura 310SC Elite is a contemporary square deadbolt, the Bravura 310RC Elite is a contemporary round deadbolt, the Bravura 310B Elite is a traditional round deadbolt, and the Bravura 910005 is a Grade 2 rectangle single cylinder deadbolt. The Callan 200S-G2 is a Grade 2 single cylinder with round trim. All share the Grade 2 cylinder x thumbturn function of the Sure-Loc commercial deadbolt.
22) What finish does the Sure-Loc Grade 2 deadbolt come in?
Satin chrome, 26D. That is the standard commercial finish, so it lines up with 26D levers, closers and exit trim already on most commercial openings, and with the rest of the Sure-Loc deadbolt line.
