Delaney Hardware 320601 – Frequently Asked Questions

1) Will the Delaney LU Series double cylinder deadbolt fit a 1-3/8 inch door, or is it only for 1-3/4 inch?
Both. The LU Series deadbolt is built for 1-3/8 inch through 1-3/4 inch doors as standard, which covers most older interior and standard commercial openings without any spacer or extension kit.
2) What door prep do I need to bore for a Delaney LU deadbolt?
Standard tubular prep: 2-1/8 inch cross bore through the face, 1 inch edge bore. Latch face prep depends on the backset you order, 1-1/8 x 2-1/4 inches for the 2-3/4 inch backset and 1 x 2-1/4 inches for the 2-3/8 inch. Strike prep is 1-1/8 x 2-3/4 inches. If the door already has a tubular deadbolt in it, you are likely dropping straight into the existing holes.
3) Do I have to pick a backset when ordering the Delaney LU deadbolt, and which one is UL?
Backset is a required selection, 2-3/4 inch or 2-3/8 inch. The 2-3/4 inch is the UL latch standard on this deadbolt. The 9091 latch itself is adjustable between the two, but the face plate cut differs, so order to the prep in your door.
4) Is a double cylinder deadbolt the right choice, or should I use a cylinder and thumbturn?
Double cylinder means key on both sides, no thumbturn. That's what you want on a door with glass beside or in it, where a thumbturn could be reached through a broken pane. It's the wrong choice on an egress door in occupied space, since nobody gets out without a key. If you need key outside and turn inside, ZenSupply carries the Hager 3215 and the Dexter DB2000 single cylinder in the same Grade 2 class.
5) Can I put the Delaney LU deadbolt on a fire rated door?
Yes. The LU Series deadbolt carries a UL 3 hour fire rating, and the bolt itself is rated 3-hour with a full 1 inch throw. Order the 2-3/4 inch backset with the 9091 UL latch to keep the listed configuration.
6) Will the Delaney LU deadbolt key into my existing Schlage keys?
Standard build is an SC4 6-pin keyway, and SC1 5-pin is available as an option, so it can be cut to Schlage-type keys. KW1 5-pin is also offered if the building runs Kwikset keys. Keying is a required choice, keyed different or keyed alike, so if you are doing a run of units on one key, say so on the order.
7) What is a direct alternative to the Delaney LU Series Grade 2 double cylinder deadbolt from another brand?
The Dexter DB2000 Series double cylinder deadbolt is the closest match in function and grade - it is a Grade 2 double cylinder deadbolt covering 1-3/8 inch to 1-3/4 inch doors, the same thickness range the Delaney LU Series double cylinder deadbolt is built for. The Hager 3214 is another Grade 2 double cylinder option for 1-3/8 inch to 1-3/4 inch doors and is supplied with a Schlage C keyway, which lines up with the SC4 6-pin keyway the Delaney LU carries as standard.
8) I need a heavier duty double cylinder deadbolt than a Grade 2 - what should I look at?
Two Grade 1 double cylinder deadbolts step up from the Grade 2 Delaney LU Series. The Design Hardware D1 Series double cylinder deadbolt is Grade 1, rated extra heavy duty, and built for 1-3/4 inch doors. The Dexter DB1000 Series double cylinder deadbolt is also Grade 1 and covers a wider 1-3/8 inch to 1-7/8 inch door thickness range, so it suits openings thicker than the 1-3/4 inch ceiling of the Delaney LU.
9) My local code will not allow a double cylinder deadbolt on this exit door. What is the equivalent with a thumbturn inside?
Stay in the same commercial Grade 2 tier and switch to a cylinder by thumbturn model. The Dexter DB2000 Series single cylinder deadbolt is Grade 2 for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw over the same thickness range - the same 1 inch full throw the Delaney LU bolt provides. The Arrow DBX61 and the Cal-Royal CB160 are further Grade 2 cylinder by thumbturn choices, the CB160 adding a tamper-resistant cylinder guard.
10) I want a small format interchangeable core deadbolt instead of a keyed cylinder - which one?
The Delaney LU Series deadbolt offers an optional small-format 6-pin interchangeable core. If you prefer a body supplied prepped for SFIC less core so your own cores go in, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt with a 2-3/4 inch backset. Both are single cylinder, so the inside becomes a thumbturn rather than a second keyed cylinder.
11) Which items that come up in a deadbolt search are not actually a replacement for a bored deadbolt like the Delaney LU?
Several. The Arrow 460 is a mortise lock strike, not a lock. The BEST 8T is a tubular deadbolt tube component, and the Baldwin Reserve 8BR0618001 is a deadbolt spacer - both are parts rather than a complete deadbolt. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, which need a mortise pocket rather than the 2-1/8 inch cross bore and 1 inch edge bore the Delaney LU Series is prepped for. The Codelocks CL2200 is an electronic surface deadbolt and the Dormakaba Saffire LX-D is an RFID electronic deadbolt, both credential-driven rather than key operated.
12) The door on my job is thicker than 1-3/4 inches. What deadbolt fits?
The Delaney LU Series deadbolt is built for 1-3/8 inch to 1-3/4 inch doors as standard. For thicker stock, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch, and the Deltana 7312KA2 Grade 3 double cylinder deadbolt covers 1-3/8 inch to 2 inch. The Dexter DB1000 Grade 1 reaches 1-7/8 inch. Note the DL3011 is a cylinder by blank configuration, not keyed on both faces.
13) Which alternative deadbolts are also fire rated like the Delaney LU?
The Delaney LU Series deadbolt carries a UL 3 hour fire rating with its 9091 UL latch. Among alternatives, the Hager 3115, 3214 and 3215 Grade 2 deadbolts and the Hager 3118 Grade 1 classroom deadbolt are all listed as fire rated for 1-3/8 inch to 1-3/4 inch doors. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
14) Can I run the Delaney LU deadbolt on an interchangeable core system?
An optional small-format 6-pin interchangeable core version is available, which is what you want if your facility rekeys with control keys rather than pulling cylinders. If you need an SFIC deadlock less core from another brand, the Arrow E61 in 26D is the SFIC-prep equivalent we carry.
15) What comes in the box with the Delaney LU deadbolt, and do I need anything else for a metal door?
Strike (9111) with a reinforcement plate, the 9091 adjustable latch, and combination screws that work in either wood or hollow metal, plus 3 inch security screws for the strike. On a wood jamb those 3 inch screws should catch the framing behind the buck. Nothing else is needed beyond the door prep itself.
16) Is Grade 2 enough for an apartment or small commercial entry door?
Grade 2 is the medium-duty commercial tier and it's the usual specification for multi-family entries and light commercial back doors. The LU Series is catalogued commercial, with a hardened steel rod in the bolt and a free spinning cylinder collar to resist wrench attack. For a high-abuse opening or a spec that calls out Grade 1, look at the Design Hardware D1 Series double cylinder or the Dexter DB1000 double cylinder instead.
17) Is there a double cylinder deadbolt for a residential-grade opening instead of a commercial one?
The Delaney LU Series double cylinder deadbolt is specified for commercial use at Grade 2. If the opening does not need that duty level, the Callan Model 210S is a Grade 3 double cylinder deadbolt, and the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt covering 1-3/8 inch to 2 inch doors, which reaches thicker doors than the Delaney LU range.
18) What deadbolt should I use on a door that only needs to lock from the inside, with no key at all?
That calls for a non-keyed deadlock rather than the keyed Delaney LU Series double cylinder deadbolt. The Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and a thumbturn inside, for 1-3/8 inch to 1-3/4 inch doors - the same thickness range the Delaney LU covers. For a door that takes hardware on one face only, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt.
19) I need a classroom function deadbolt, not a double cylinder. What are my options?
The Delaney LU Series is a double cylinder deadbolt, keyed on both faces. For classroom function, the Falcon D211 is a Grade 2 medium duty classroom deadbolt with single cylinder operation, and the Falcon D111 is the Grade 1 heavy duty classroom deadbolt with adjustable backset. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder, which matches the 6-pin SC4 keying the Delaney LU uses as standard.
20) Is there a deadbolt with an adjustable backset instead of ordering a fixed 2-3/8 or 2-3/4?
The Delaney LU Series deadbolt uses an adjustable 9091 UL latch covering both 2-3/8 inch and 2-3/4 inch backsets, with 2-3/4 inch as the UL standard. If you want the same flexibility in another line, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Brinks Raleigh and Mendocino Series single cylinder deadbolts use a 4-way adjustable backset. The Falcon D111 Grade 1 classroom deadbolt also has an adjustable backset.
21) Will a Delaney LU deadbolt in stainless match my other 26D hardware?
The finish is US32D satin stainless steel, which sits alongside 26D satin chrome on most openings and is the standard commercial look. If you are standardizing a building, US32D is the finish to hold across levers, closers and exit trim.
22) I need a decorative double cylinder deadbolt for a residential entry rather than a plain stainless commercial one.
The Delaney LU Series double cylinder deadbolt comes in a US32D stainless steel finish with commercial trim. For a decorative face, the Baldwin Reserve double cylinder deadbolt is offered in contemporary round and contemporary square trim, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt.
