Delaney Hardware 320601 – Frequently Asked Questions

1) Will the Delaney LU Series deadbolt fit a 1-3/8 inch door, or is it 1-3/4 only?
The LU Series Grade 2 deadbolt is built for doors from 1-3/8 to 1-3/4 inches thick, so it covers both the older interior thickness and standard commercial 1-3/4 inch doors. Door prep is a 2-1/8 inch cross bore with a 1 inch edge bore, which is standard tubular prep.
2) Does the Delaney LU deadbolt come in a 2-3/8 inch backset for a residential door?
Both backsets are available. The UL latch ships standard at 2-3/4 inches, and 2-3/8 inches is the optional selection; the 9091 UL latch itself is adjustable between the two. Backset is a required choice when ordering. Note the latch face differs: 1-1/8 x 2-1/4 inches at the 2-3/4 backset, 1 x 2-1/4 inches at 2-3/8.
3) Is a double cylinder deadbolt legal and right for my application, or should I use a single cylinder with a thumbturn?
The LU Series is keyed on both sides, with no thumbturn. That is what you want on a glass-adjacent or sidelite door where a thumbturn could be reached from outside. It also means nobody exits without a key, which many egress codes do not allow on a required exit. If you need keyed outside and thumbturn inside, go with a cylinder x thumbturn model such as the Hager 3215 or the Dexter DB2000 single cylinder, both Grade 2.
4) Can I use this deadbolt on a fire rated door?
Yes. The LU Series carries a UL 3 hour fire rating, and the bolt itself is rated for 3 hours with a full 1 inch throw. Keep in mind a keyed-both-sides deadbolt is often not permitted on a required egress door regardless of the fire rating, so confirm the opening's egress function before you specify it.
5) Will this deadbolt latch into my existing strike?
The bolt has a full 1 inch throw and ships with a 1-1/8 x 2-3/4 inch strike (9111) plus a reinforcement plate. That is the common ANSI-style commercial strike footprint, so if your frame is prepped for a 1-1/8 x 2-3/4 strike it drops in. A frame cut for a larger 1-1/4 x 4-7/8 ANSI strike will leave a gap and needs a filler or new frame prep.
6) What keyway does the Delaney LU deadbolt use, and can I key it to my existing Schlage or Kwikset keys?
Standard is an SC4 6-pin keyway. KW1 5-pin and SC1 5-pin are also available if you need to match existing Kwikset or 5-pin Schlage keys on the building. Keying is a required selection: keyed different, keyed alike, or keyed to an existing system.
7) What is a direct equivalent to the Delaney LU Series Grade 2 double cylinder deadbolt from another brand?
The closest straight equivalent is the Dexter DB2000 Series Grade 2 double cylinder deadbolt, which carries the same Grade 2 rating and double cylinder function and fits 1-3/8 inch to 1-3/4 inch doors, matching the Delaney LU door thickness range. The Hager 3214 is another Grade 2 double cylinder option for 1-3/8 inch to 1-3/4 inch doors and is fire rated, like the UL 3 hour rated LU bolt.
8) If a Grade 1 double cylinder deadbolt is required instead of Grade 2, what should be used?
Step up to the Design Hardware D1 Series Grade 1 double cylinder deadbolt, rated extra heavy duty for 1-3/4 inch doors, or the Dexter DB1000 Series Grade 1 double cylinder deadbolt for 1-3/8 inch to 1-7/8 inch doors. The Delaney LU Series is Grade 2, so where a spec calls for ANSI Grade 1 double cylinder these are the ones to quote.
9) Is the Delaney LU single cylinder deadbolt an alternative if a thumbturn is needed inside?
The Delaney LU Series deadbolt is double cylinder, keyed on both sides, with no thumbturn. For a cylinder by thumbturn opening in the same Grade 2 class, the Dexter DB2000 single cylinder deadbolt fits 1-3/8 inch to 1-3/4 inch doors, the Hager 3215 is a Grade 2 single cylinder with a 1 inch throw, and the Cal-Royal CB160 is a Grade 2 single cylinder with a tamper-resistant cylinder guard.
10) Will a mortise deadbolt work in place of the Delaney LU Series deadbolt?
No. The Delaney LU Series is a bored deadbolt needing a 2-1/8 inch cross bore and 1 inch edge bore with a 2-3/8 inch or 2-3/4 inch backset. Mortise-prepped units such as the Dormakaba D900 small case mortise deadbolt or the Emtek 2050 European mortise deadbolt with integrated roller latch require a mortise pocket in the door edge instead, so they are not drop-in substitutes for a bored prep.
11) What should be used instead of the Delaney LU deadbolt on a door that must allow free egress without a key?
A double cylinder deadbolt like the Delaney LU Series requires a key on the inside as well as the outside. Where keyless egress is needed, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate by thumbturn function for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for the same thickness range.
12) What looks like a substitute for the Delaney LU deadbolt but is actually only a component or accessory?
Several items with deadbolt in the name are not complete locks. The BEST 8T T Series tubular deadbolt tube component is a tube assembly, the Baldwin Reserve 8BR0618001 is a deadbolt spacer, and the Arrow 460 is a mortise lock strike for latchbolt by deadbolt functions. The Delaney LU Series ships as a complete Grade 2 double cylinder deadbolt with a 9111 strike, reinforcement plate, combination wood or metal screws and 3 inch security screws.
13) What should be specified for a door thicker than the Delaney LU Series range?
The Delaney LU Series is set up 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 doors, and the Deltana 7312KA2 double cylinder deadbolt covers 1-3/8 inch to 2 inch doors.
14) Does this deadbolt work on a hollow metal door, or only wood?
Both. The LU Series ships with combination screws that suit wood or metal door mounting, plus 3 inch security screws for the strike into the frame. Prep is the same either way: 2-1/8 inch cross bore, 1 inch edge bore.
15) Is a Grade 2 deadbolt enough for an apartment or office entry, or do I need Grade 1?
Grade 2 is the standard commercial medium duty tier and is commonly used on multi-family and office entries. If the opening sees heavy traffic or abuse, or a spec calls Grade 1, step up to a Grade 1 double cylinder like the Design Hardware D1 Series or the Dexter DB1000 double cylinder. Both are keyed both sides like the LU.
16) What keeps the cylinder from being wrenched or attacked on this deadbolt?
Three things on the LU Series: a protection sleeve over the cylinder, a free spinning cylinder collar that defeats wrench attacks, and a hardened steel rod insert in the bolt to resist sawing. The 3 inch security screws anchor the strike into the frame stud rather than just the jamb.
17) Looking for a double cylinder deadbolt for a storefront or decorative entry instead of a plain commercial one. What else is there?
The Delaney LU is a plain commercial trim, Grade 2, keyed both sides. For decorative double cylinder trim we also carry the Baldwin Reserve contemporary round and square deadbolts, the Baldwin Estates 8011 contemporary, and the Emtek 8323 Modern Disc in brass. For a lower cost keyed-both-sides option, the Callan 210S is Grade 3 and the Deltana 7312KA2 is Grade 3 with a 1-3/8 to 2 inch door thickness range.
18) Does the Delaney LU deadbolt have a handing I need to specify?
No handing to specify. It is a bored tubular deadbolt with a square corner 1 x 2-1/4 inch faceplate and an adjustable latch, so it works on either hand. What you do have to specify is backset (2-3/4 or 2-3/8) and the keying.
19) What alternative accepts a small format interchangeable core if the Delaney LU keyway is not wanted?
The Delaney LU Series is SC4 6-pin standard with an optional small-format 6-pin interchangeable core, and KW1 5-pin and SC1 5-pin keyways can also be specified. If a factory SFIC-prepped unit is preferred, the Arrow E61 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.
20) What is a lighter-duty double cylinder deadbolt than the Delaney LU Series?
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. The Delaney LU Series is a Grade 2 commercial deadbolt, so these Grade 3 units sit a grade below it for lower-traffic openings.
21) Is a Baldwin double cylinder deadbolt interchangeable with the Delaney LU Series?
Both are double cylinder deadbolts, but the Baldwin Reserve contemporary round and square double cylinder deadbolts and the Baldwin Estates 8011 contemporary 1-5/8 inch double cylinder are decorative residential-styled trims, while the Delaney LU Series is a commercial Grade 2 bolt with a UL 3 hour fire rating, hardened steel rod latch insert and protection sleeve. They share the function, not the duty class.
22) What is the alternative if a classroom-function deadbolt is specified rather than a double cylinder one?
The Falcon D211 is a Grade 2 classroom function deadbolt with single cylinder operation, and the Falcon D111 is the Grade 1 classroom deadbolt with adjustable backset. The Delaney LU Series is a Grade 2 double cylinder deadbolt, keyed both sides, so it does not cover a classroom function call-out.
23) Is there an electronic or keypad alternative to the Delaney LU double cylinder deadbolt?
Yes, if mechanical keying is not required. The Codelocks CL2200 is a medium duty electronic surface deadbolt, the Codelocks CL2210 is an electronic mortise deadbolt, and the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt. The Delaney LU Series is a mechanical bolt keyed on both sides with SC4 6-pin cylinders, so switching to electronic changes both the credential and the door prep.
24) What finish does the Delaney LU deadbolt come in, and will it match our other stainless lever hardware?
It is supplied in US32D stainless steel, the satin stainless commercial finish that pairs with 630 and other brushed stainless trim. If your building is standardized on satin chrome 626, expect a slight tone difference between the two.
25) What is a Grade 2 alternative to the Delaney LU deadbolt for a single cylinder storefront or secondary door in a stainless-look finish?
The Delaney LU Series is offered in US32D stainless steel with a double cylinder function. For a single cylinder Grade 2 alternative, the Arrow DBX61 and the Bravura 310B Elite are both Grade 2 cylinder by thumbturn deadbolts, and the Callan 200S-G2 is a Grade 2 single cylinder round trim deadbolt.
