Delaney Hardware 300602 – Frequently Asked Questions

1) Will the Delaney LU Series deadbolt fit a 1-3/8 inch door, or do I need a 1-3/4 inch door?
Both. The LU Series deadbolt is built for 1-3/8 inch through 1-3/4 inch doors as standard, which covers the usual commercial 1-3/4 inch leaf and the thinner older interior doors you still run into on apartment turns. Door prep is a 2-1/8 inch cross bore with a 1 inch edge bore, so it drops into a standard bored prep.
2) What backset do I order for a Delaney LU deadbolt, and can I use it on a door already bored at 2-3/8 inches?
Backset is a required choice at order time, 2-3/4 inch or 2-3/8 inch, so a door already bored at 2-3/8 is covered. The 2-3/4 inch version is the UL latch standard. The latch itself (9091 UL) is adjustable between 2-3/8 and 2-3/4, but the latch face differs by backset: 1-1/8 x 2-1/4 inches on the 2-3/4, and 1 x 2-1/4 inches on the 2-3/8, so the mortise pocket in the door edge has to match what you order.
3) Will this Delaney deadbolt latch into the strike plate that is already in my frame?
The LU deadbolt ships with a 1-1/8 x 2-3/4 inch strike (9111) plus a reinforcement plate, which is the common ANSI-style deadbolt strike footprint. Bolt throw is a full 1 inch, so the frame pocket behind the strike has to be deep enough to take it. If your existing strike is a different size, use the supplied one and the reinforcer rather than trying to reuse the old plate, since the fire rating rides on the supplied latch and strike.
4) Can I key this Delaney LU deadbolt to my existing Schlage or Kwikset keys?
Keyway is a selectable option: SC4 6-pin as standard, or SC1 5-pin, or KW1 5-pin. SC1 and SC4 are the Schlage keyways and KW1 is the Kwikset one, so a building already on either system can stay on it. Keying is a required selection too, keyed different or keyed alike, so a property manager rekeying a block of units can put them all on one key.
5) Is a Grade 2 deadbolt enough for an apartment entry door, or should I step up to Grade 1?
Grade 2 is the standard for multi-family and light commercial entry, and the LU Series is a commercial-rated Grade 2 with a hardened steel rod latch insert, a cylinder protection sleeve and a free spinning collar, which are the anti-attack features that matter on a tenant door. For a high-abuse opening or a spec that calls out Grade 1, step to something like the Dexter DB1000 Series single cylinder deadbolt or the Deltana CL200LM, both Grade 1 cylinder x thumbturn deadbolts.
6) What is a fire rated alternative to the Delaney LU Series deadbolt?
The Delaney LU Series uses a UL 3 hour fire rated latch with a full 1 inch throw bolt. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3 hour fire rated latch and the same cylinder x thumbturn function. The Hager 3215 is a Grade 2 single cylinder commercial deadbolt with a 1 inch throw, carries a fire rating, and covers 1-3/8 inch to 1-3/4 inch doors, matching the LU Series door thickness range.
7) I need a deadbolt that takes a small format interchangeable core. What are my options?
The Delaney LU Series offers an optional small format 6-pin interchangeable core alongside its standard SC4 6-pin keyway. The Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC and supplied less core, for 1-3/8 inch to 1-3/4 inch doors. The Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt supplied non-cylinder with a 2-3/4 inch backset, which is the same backset the LU Series uses as its UL latch standard.
8) What deadbolt should I use if the opening needs a key on both sides instead of a thumbturn?
The Delaney LU Series is a single cylinder deadbolt, keyed outside with a thumbturn inside. For a key on both sides at the same Grade 2 level, the Dexter DB2000 double cylinder deadbolt covers 1-3/8 inch to 1-3/4 inch doors, and the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway over the same 1-3/8 inch to 1-3/4 inch range. At Grade 1, the Design Hardware D1 Series double cylinder is rated extra heavy duty for 1-3/4 inch doors, and the Dexter DB1000 double cylinder covers 1-3/8 inch to 1-7/8 inch. Verify that a double cylinder is permitted on the egress door before specifying it.
9) What is a Grade 1 equivalent to the Delaney LU Series single cylinder deadbolt?
The Delaney LU Series is a Grade 2 single cylinder deadbolt with a cylinder x thumbturn function. If a Grade 1 deadbolt is required, the Dexter DB1000 series single cylinder deadbolt is Grade 1 with the same cylinder x thumbturn function and a 1-3/8 inch to 1-7/8 inch door thickness range. The Accentra D111 is also a Grade 1 single cylinder deadbolt, cylinder x thumbturn, with a 2-3/8 inch backset and a 1-3/8 inch to 1-3/4 inch door thickness range. The Deltana CL200LM is a Grade 1 single cylinder deadbolt, cylinder x thumbturn, as well.
10) What can I use on a stairwell or exit door where the inside needs a turn but no key outside?
The Delaney LU Series takes a key on the outside and a thumbturn inside. Where the outside face should carry no cylinder at all, the Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and a thumbturn inside, for 1-3/8 inch to 1-3/4 inch doors. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock with a cylinder outside and a blank inside face, which is the opposite arrangement and is used where the inside must not release the bolt.
11) Will the Delaney LU Series deadbolt work on a door thicker than 1-3/4 inches?
The Delaney LU Series is built for 1-3/8 inch to 1-3/4 inch doors as standard. For a thicker door, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch, and the Deltana 7312KA2 double cylinder deadbolt covers 1-3/8 inch to 2 inch. Confirm the door thickness at the cross bore before ordering either.
12) What looks like a substitute for the Delaney LU Series deadbolt but will not drop into the same door prep?
The Delaney LU Series is a bored deadbolt requiring a 2-1/8 inch cross bore and a 1 inch edge bore. Several deadbolts sold under the same word are not bored units. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, cut into a mortise pocket rather than a bore. The Dormakaba D900 is a small case mortise dead bolt. The Codelocks CL200 is a surface mounted deadbolt with key override, and the Arrow 460 is a mortise lock strike, not a lock body at all. None of these fit a 2-1/8 inch cross bore prep.
13) What deadbolt do I use on an aluminum storefront or narrow stile door instead of the Delaney LU Series?
The Delaney LU Series is a bored deadbolt needing a 2-1/8 inch cross bore, which a narrow stile does not offer. The International Door Closers DH-1821 is a hook bolt deadlock with a flat faceplate, a hook bolt being the usual choice where the frame cannot accept a straight throw. The DT-1851 is a long throw deadlatch lock and the DL-4511 is a deadlatch lock, both with flat faceplates. These are lock cases fitted into the stile rather than bored trim sets.
14) Does the Delaney LU deadbolt come with screws for a hollow metal door, or do I need to buy them?
Screws are in the box and they are combination screws that suit either wood or metal door mounting, so you are not sourcing separate fasteners for hollow metal frames. Three inch security screws are included as well, which is what you want going into the strike side to reach the framing rather than just the jamb. The strike reinforcement plate is included too.
15) What finishes does the Delaney LU Series deadbolt come in, and will it match the rest of my hardware?
Three finishes: US32D satin stainless steel, US26D satin chrome, and US19 matte black. US32D and US26D both read as a brushed or bright silver and are the two most common commercial finishes, so it will sit alongside existing lever sets and closers on a typical commercial opening. US19 matte black is there for the newer black-hardware packages.
16) What are the closest alternatives to the Delaney LU Grade 2 deadbolt from other brands?
Straight swaps at the same grade and function (cylinder x thumbturn, Grade 2) include the Arrow DBX61, the Cal-Royal CB160 with its tamper-resistant cylinder guard, the Dexter DB2000 single cylinder, and the Bravura 310B Elite. The Hager 3215 is the nearest on spec, a Grade 2 single cylinder with a 1 inch throw for 1-3/8 to 1-3/4 inch doors and a fire rating, matching the LU on throw and thickness range. Pick on keyway and finish, since the fit envelope is essentially the same across them.
17) Do I need to worry about handing when ordering a Delaney LU deadbolt?
No handing to specify. The LU is a bored deadbolt, cylinder outside and thumbturn inside, so it installs the same on a left or right hand door. What you do have to specify is the backset (2-3/4 or 2-3/8 inch) and the keying, both of which are required selections. Handing only becomes a question on the lockset or exit device sharing the opening, not on this bolt.
18) Can I put a Delaney LU deadbolt above an existing lever set to add a second lock?
Yes, it installs as an independent bored deadbolt on its own 2-1/8 inch cross bore with a 1 inch edge bore, so it goes in above a knob or lever with no interconnection between them. That means two separate motions to lock up. If you want one lever that retracts the latch and bolt together for a tenant entry, an interconnected lock like the Falcon H2101 Grade 2 entrance set with a single cylinder deadbolt does that in one device.
19) Is there a lighter duty deadbolt than the Delaney LU Series for interior or low traffic doors?
The Delaney LU Series carries a Grade 2 rating for commercial use. For openings that do not call for Grade 2, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal LSD is a Grade 3 single cylinder deadbolt over the same door thickness range with an ADA ergonomic thumbturn. The Callan Model 200S is a Grade 3 single cylinder deadbolt with square trim.
20) Is there an electronic deadbolt I can use instead of a keyed Delaney LU Series?
The Delaney LU Series is a mechanical deadbolt keyed to an SC4, KW1 or SC1 keyway. If credentials rather than keys are wanted, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt. The Codelocks CL2200 is a medium duty electronic surface deadbolt in a brushed steel finish, and the Codelocks CL2210 is an electronic mortise deadbolt. The surface and mortise units do not use the same door prep as a bored deadbolt.
21) What is the difference between the Delaney LU Series deadbolt and a classroom function deadbolt?
The Delaney LU Series is a single cylinder deadbolt, cylinder x thumbturn, so the bolt throws by key outside or by turn inside. The Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset, and the Falcon D211 is the Grade 2 medium duty classroom function version; both are listed as cylinder x thumbturn. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder over a 1-3/8 inch to 1-3/4 inch door thickness range. Classroom function governs who may secure the door, so confirm the function called for on the door schedule before substituting.
22) The Delaney LU Series needs a full cross bore. What if the door can only take a bore on one side?
The Delaney LU Series requires a 2-1/8 inch cross bore through the door plus a 1 inch edge bore. Where a through bore is not possible, the Callan Model 205S is a Grade 3 one sided half-bore deadbolt. For a fully surface applied approach, the Codelocks CL200 is a surface deadbolt with key override, which mounts to the door face rather than into a bore.
23) Can a Delaney LU Series deadbolt replace an interconnected entry lock?
The Delaney LU Series is a standalone deadbolt with a cylinder x thumbturn function and no latch or lever. The Falcon H2101 is a Grade 2 entrance interconnected lock that carries a single cylinder deadbolt together with the latching trim in one assembly. If the existing opening is interconnected, a standalone deadbolt covers only the deadbolt half of that prep and a separate latchset is needed to complete the door.
24) Is a deadbolt spacer or tube component a substitute for a complete Delaney LU Series deadbolt?
The Delaney LU Series ships as a complete deadbolt with a 9091 UL adjustable latch, a 1-1/8 inch by 2-3/4 inch 9111 strike with reinforcement plate, and combination screws for wood or metal doors. The BEST 8T is a T Series tubular deadbolt tube component and the Baldwin Reserve 8BR0618001 is a deadbolt spacer, both of which are pieces fitted to an existing deadbolt rather than a lock that secures a door on its own.
25) I want a deadbolt with contemporary square trim instead of the round trim on the Delaney LU Series. What matches?
The Delaney LU Series comes in US32D satin stainless steel, US26D satin chrome and US19 matte black. For a squared trim in the same Grade 2 cylinder x thumbturn function, the Bravura 310SC Elite is a contemporary square deadbolt and the Bravura rectangle deadbolt is a Grade 2 single cylinder with rectangular trim. The Bravura 310RC Elite is the contemporary round version at the same grade and function. The Brinks Mendocino is a contemporary square single cylinder deadbolt with a 4 way adjustable backset.
