Delaney Hardware 301702 – Frequently Asked Questions

1) Does the Delaney LM Series deadbolt come with a cylinder, or do I have to supply the core?
It ships less core. The LM Series is a single cylinder deadbolt (cylinder outside, thumbturn inside) prepped for an optional small-format interchangeable core in 6-pin or 7-pin, so you supply and key the core to your existing system. If you want a deadbolt that comes complete with its own keyed cylinder, the Dexter DB1000 Grade 1 single cylinder or the Deltana CL200LM Grade 1 single cylinder are alternatives.
2) What door thickness will this Delaney LM deadbolt fit?
Standard range is 1-9/16 inch through 2 inch doors, so it covers 1-3/4 inch commercial doors and thicker stock up to 2 inches. If your doors are 1-3/8 inch, this is the wrong part; a Dexter DB2000 Grade 2 or Hager 3215 covers 1-3/8 to 1-3/4 inch instead.
3) Which backset do I have to specify when ordering the Delaney LM deadbolt?
Backset is a required choice: 2-3/4 inch or 2-3/8 inch. The 2-3/4 inch deadbolt latch (9058) is the UL standard option; 2-3/8 inch (9057) is optional. The faceplate changes with it, 1-1/8 x 2-1/4 inches on the 2-3/4 backset and 1 x 2-1/4 inches square corner on the 2-3/8. Measure from the door edge to the center of the 2-1/8 inch cross bore before you order.
4) Will the Delaney LM deadbolt drop into an existing 2-1/8 inch bored door?
Yes, it uses standard bored prep: 2-1/8 inch cross bore and 1 inch edge bore. Latch face prep is 1-1/8 x 2-1/4 inches for the 2-3/4 backset or 1 x 2-1/4 inches for the 2-3/8 backset. If the existing deadbolt faceplate mortise matches that, it is a straight swap with no new boring.
5) Can I use this deadbolt on a 3-hour fire rated opening?
The bolt carries a 3 hour fire rating and throws a full 1 inch. It is a Grade 1 commercial deadbolt, which is the level institutional and MRO specs usually call for on exterior and stair doors.
6) Which other deadbolt accepts a small format interchangeable core like the Delaney LM less core version?
The Delaney LM Series less core deadbolt is prepped for optional small-format 6-pin or 7-pin interchangeable cores. Two other SFIC-style options exist: the Arrow E61 Grade 2 single cylinder deadlock is supplied 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 single deadbolt with a 2-3/4 inch backset. Both are Grade 2 where the Delaney LM is Grade 1.
7) What is an equivalent Grade 1 single cylinder deadbolt if the Delaney LM Series is not the right fit?
Several Grade 1 cylinder x thumbturn deadbolts cover the same function as the Delaney LM Series. The Dexter DB1000 single cylinder deadbolt is Grade 1 cylinder x thumbturn with a 1-3/8 inch to 1-7/8 inch door thickness range, the Deltana CL200LM is a Grade 1 single cylinder deadbolt in the same function, and the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt with a 2-3/8 inch backset and a 1-3/8 inch to 1-3/4 inch door thickness range. The Delaney LM is ordered with a 2-3/4 inch or 2-3/8 inch backset and covers 1-9/16 inch through 2 inch doors.
8) What should I use instead of the Delaney LM deadbolt if the door needs a key on both sides?
The Delaney LM Series is single cylinder, cylinder x thumbturn, so it keys one side only. For double cylinder operation, the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt for 1-3/4 inch doors rated extra heavy duty, the Dexter DB1000 double cylinder is Grade 1 for 1-3/8 inch to 1-7/8 inch doors, and the Hager 3214 is a Grade 2 double cylinder deadbolt for 1-3/8 inch to 1-3/4 inch doors. Double cylinder deadbolts are restricted on many egress doors, so confirm code for the opening.
9) Which deadbolt can I standardize on for a fire rated door if I am not using the Delaney LM?
The Delaney LM Series deadbolt uses a full 1 inch throw bolt with a 3 hour fire rating. Among alternatives, the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Hager 3118 is a Grade 1 classroom deadbolt listed as fire rated with a Schlage C keyway and 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors. The Delaney LM is supplied less core for small-format interchangeable cylinders instead of a fixed keyway.
10) My doors are thicker than 1-3/4 inches. Which deadbolts handle that besides the Delaney LM?
The Delaney LM Series is standard for 1-9/16 inch through 2 inch doors. Among alternatives, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch doors, and the Deltana 7312KA2 Grade 3 double cylinder deadbolt covers 1-3/8 inch to 2 inch doors. Many of the Grade 2 options, such as the Hager 3115 and Dexter DB2000 single cylinder, stop at 1-3/4 inches.
11) What strike comes with the Delaney LM Series deadbolt, and do I need a reinforcement plate separately?
A 1-1/8 x 2-1/4 inch strike (9121) is included along with a reinforcement plate, so the frame side is covered in the box. It also comes with 3 inch security screws and combination screws that work for either wood or metal door mounting.
12) Will this dull chrome deadbolt match the satin chrome hardware already on my building's doors?
The finish is US26D dull chrome (satin chrome), the standard commercial satin chrome code, so it matches other US26D levers, closers, and exit trim on the same openings. US26D is the only finish offered on this LM Series deadbolt.
13) Can I mount this deadbolt on a hollow metal door, or is it wood only?
Both. The LM Series ships with combination screws suited to wood or metal door mounting, so the same deadbolt covers hollow metal and wood leaves as long as the door is 1-9/16 to 2 inches thick and bored 2-1/8 inch cross bore with a 1 inch edge bore.
14) Is there a lighter duty alternative to the Delaney LM Grade 1 deadbolt for low traffic doors?
Yes. The Delaney LM Series is a Grade 1 commercial deadbolt; for lower traffic openings the Arrow DBX61 and Cal-Royal CB160 are Grade 2 cylinder x thumbturn deadbolts, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal ED500 is a Grade 3 cylinder x thumbturn deadbolt with an adjustable backset. Note the Delaney LM covers doors up to 2 inches thick, which those ranges do not.
15) If the opening needs a non-keyed thumbturn instead of a cylinder, what replaces the Delaney LM deadbolt?
The Delaney LM Series is a keyed single cylinder deadbolt with a thumbturn inside. For a non-keyed opening, 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 Callan 205S is a Grade 3 one-sided half-bore deadbolt, which suits doors where only one face takes hardware.
16) Does the Corbin Russwin DL3011 do the same job as the Delaney LM Series deadbolt?
Not the same configuration. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock with cylinder outside and a blank plate inside for 1-3/4 inch to 2-1/4 inch doors, so there is no inside thumbturn to retract the bolt. The Delaney LM Series is cylinder x thumbturn, keyed outside with a turn inside. If you want the Delaney function in that family, the cylinder x blank DL3211 and DL2211 are also blank-inside designs rather than thumbturn.
17) The Delaney LM needs a 2-1/8 inch cross bore. What deadbolt options exist for doors without that prep?
The Delaney LM Series requires a 2-1/8 inch cross bore and 1 inch edge bore. For doors you do not want to bore through, the Codelocks CL200 is a surface mounted deadbolt with key override, the Codelocks CL2200 is an electronic surface deadbolt in brushed steel, and the Callan 205S is a one-sided half-bore deadbolt. These are different operating designs rather than drop-in replacements for a bored cylinder x thumbturn deadbolt.
18) Will an Arrow 460 strike work as the strike for a Delaney LM deadbolt?
No. The Arrow 460 is a mortise lock strike for latchbolt by deadbolt functions with a straight lip, intended for mortise lock cases on 1-3/4 inch doors. The Delaney LM Series bored deadbolt ships with a 1-1/8 inch by 2-1/4 inch strike, number 9121, and a reinforcement plate, so the correct strike is already included.
19) What electronic deadbolt would I use on a multi-family unit door instead of the Delaney LM keyed deadbolt?
The Delaney LM Series is a mechanical Grade 1 single cylinder deadbolt operated by key outside and thumbturn inside. For credential-based access on unit doors, the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Codelocks CL2210 is an electronic mortise deadbolt. These require different door prep and power or battery provisions than a bored mechanical deadbolt.
20) Does this deadbolt have any protection against cylinder attack or wrenching?
Three features address that: a protection sleeve, a hardened steel rod insert in the bolt, and a free spinning cylinder collar that defeats wrench and pipe attacks on the outside trim. The included 3 inch security screws anchor the assembly through the door rather than into the trim alone.
21) Is the BEST 8T tubular deadbolt tube component a substitute for the Delaney LM deadbolt?
No. The BEST 8T T Series item is a tubular deadbolt tube component, a piece of a lock assembly rather than a complete deadbolt. The Delaney LM Series is a complete Grade 1 single cylinder deadbolt supplied with the bolt, strike, reinforcement plate, and combination screws for wood or metal doors, less the interchangeable core.
