Arrow N44 26D – Frequently Asked Questions

1) Will the Arrow N44 deadbolt fit a 1-3/8 inch door, or is it 1-3/4 only?
Both. The N44 is built for doors 1-3/8 inch to 1-3/4 inch thick as standard, which covers the common commercial 1-3/4 inch leaf and the older 1-3/8 inch interior door. The backset is 2-3/4 inches, so the cross-bore has to sit that far in from the door edge.
2) Does the Arrow N44 come with a strike, and does it work in a wood frame?
Strikes are included for both frame types. The N44 ships standard with a #380 security strike for steel frames and a #356 security strike for wood frames, so you are not sourcing a strike separately whichever jamb you are in. The bolt throws 1 inch (25.40mm) solid brass with a hardened steel pin, and the faceplate measures 1 x 2-1/4 inches.
3) Can I use my existing Best or Falcon interchangeable cores in the Arrow N44?
Yes, with the IC cylinder option. Ordered that way the N44 accepts 6 or 7 pin small format interchangeable cores, including Best and Falcon type, and it ships less cores so you pin your own. If you order the standard cylinder instead, you get a solid brass 1-1/8 inch mortise cylinder in the Arrow A keyway, drilled for 6 pins and pinned to 5, with two brass keys.
4) Is the Arrow N44 deadbolt approved for a fire rated door?
The N44 is UL and CUL listed for use on A label or lesser doors, but only when used together with a rated primary latching device. It is a supplemental deadbolt, not the latching hardware, so the fire door still needs its rated lock or exit device.
5) What should I use instead of the Arrow N44 if the door is bored rather than mortised?
Look at a cylindrical deadlock. The Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in classroom function, cylinder by blank, for 1-3/4 inch doors. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder, for doors 1-3/8 to 1-3/4 inch. Both serve classroom locking on a bored prep, whereas the Arrow N44 is a mortise lock. Note the trim side: the DL2211 is cylinder by blank, so there is no inside thumbturn, while the N44 is cylinder by thumbturn.
6) What is the closest cross-brand equivalent to the Arrow N44 classroom deadbolt?
The Falcon D111 is the nearest match in intent. Both are classroom-function deadbolts operated cylinder by thumbturn, and the Falcon D111 is a Grade 1 heavy duty lock in the D100 Series. The difference that matters at the opening is the body: the Arrow N44 is a mortise deadbolt with a 2-3/4 inch backset and a 1 inch by 2-1/4 inch faceplate, so it needs a mortise pocket, while the Falcon D111 is supplied with an adjustable backset for a bored prep. If the door is already mortised, stay with the N44; if it is a bored door, the D111 is the one that drops in.
7) Is there an alternative to the Arrow N44 that takes an interchangeable core?
The Deltana CL200LAIC is a single cylinder interchangeable core deadbolt, Grade 2, with a 2-3/4 inch backset, supplied non-cylinder. The Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome, cylinder by thumbturn. The Arrow N44 shares that approach as a cylinder option: it accepts 6 or 7 pin small format interchangeable cores, supplied less cores, and will take Best or Falcon type cores. The Deltana and Delaney units are bored deadbolts, while the N44 is a mortise body for classroom function.
8) Do I have to order the Arrow N44 handed for a left or right hand door?
No handing to specify. All N Series functions are reversible, so one N44 covers left and right hand openings. That makes it easier to stock a couple of spares for a building with mixed swings.
9) Can I get a set of Arrow N44 deadbolts keyed alike across a building?
Yes. Keying is a required selection: keyed different is standard, keyed alike is there for running multiple locks on one key, and a None option lets you take the lock less cylinder if you are supplying your own cores. A key code field is available if you are matching an existing system.
10) What is the difference between the Arrow N44 and a standard single cylinder deadbolt like the Dexter DB1000?
Function and prep. The N44 is a mortise deadlock with a 2-3/4 inch backset, a 1 inch solid brass bolt, and interchangeable core compatibility for keyed systems. The Dexter DB1000 single cylinder is a Grade 1 tubular deadbolt for doors 1-3/8 to 1-7/8 inches, and the Deltana CL200LM is a Grade 1 cylinder by thumbturn deadbolt. Those bolt into a bored door; the N44 needs a mortise pocket, and it is aimed at keyed commercial openings where you want SFIC cores.
11) Is the Arrow N44 tough enough for a school or dorm corridor?
It is built as commercial hardware: heavy wrought steel housing with a zinc dichromate finish, a solid brass bolt with a hardened steel pin against sawing, and security strikes for both steel and wood frames. That is the construction you want on a classroom or dorm door rather than a residential tubular bolt.
12) I need a mortise deadbolt but not classroom function - what are the alternatives to the Arrow N44?
The Dormakaba D900 small case mortise deadbolt is a cylinder by thumbturn mortise deadlock supplied keyed different with SC keyways. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, cylinder by thumbturn, in square and round trim. All three are mortise bodies like the Arrow N44; the N44 is the one specified when the opening calls for classroom function and an Arrow A keyway or small format core.
13) Is there a lighter duty classroom deadbolt than the Arrow N44 for a lower traffic door?
Yes. The Falcon D211 is a Grade 2 classroom function deadbolt with single cylinder operation, rated medium duty in the D200 Series. It covers the same classroom locking behavior in a lighter duty class than a heavy wrought steel mortise body. The Arrow N44 remains the choice where the door is mortise prepped and you want interchangeable core compatibility, since the N44 accepts 6 or 7 pin small format cores of the Best or Falcon type.
14) Does the Cal-Royal CRB800 substitute for the Arrow N44?
Only partly. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, cylinder by thumbturn. It matches the Arrow N44 on cylinder by thumbturn operation, but it is a bored deadbolt rather than a mortise body, and it is a standard single cylinder deadbolt rather than classroom function. If your hardware schedule calls out classroom function in a mortise pocket with a 2-3/4 inch backset, the N44 is the item that meets it.
15) What looks like a substitute for the Arrow N44 but will not work on a mortise prepped commercial door?
Several residential-pattern deadbolts share the cylinder by thumbturn function but not the prep. The Brinks E2401 Raleigh and E2402 Mendocino are single cylinder deadbolts with a 4-way adjustable backset for bored doors. The Bravura 310B Elite and 310RC Elite are Grade 2 round trim deadbolts, and the Cal-Royal ED500 is a Grade 3 deadbolt with adjustable backset for 1-3/8 to 1-3/4 inch doors. None of these is a mortise body, and none is classroom function. The Arrow N44 is the mortise deadlock with a fixed 2-3/4 inch backset and a 1 inch solid brass bolt with a hardened steel pin.
16) What is the double cylinder alternative if the Arrow N44 thumbturn is not acceptable on my opening?
The Arrow N44 is a single cylinder lock, cylinder by thumbturn. For a keyed-both-sides opening, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for doors 1-3/8 to 1-3/4 inch, and the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors. Confirm your local code permits double keyed hardware on the egress door before specifying either.
17) What finishes does the Arrow N44 deadbolt come in?
Five: 605 bright brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, and 626 satin chrome. For most commercial corridors 626 satin chrome is the one that matches existing levers and closers.
18) Can the Arrow N44 take a high security cylinder?
Yes. Beyond the standard Arrow A keyway mortise cylinder and the small format interchangeable core option, ASSA high security cylinders are available for the N Series, so a restricted key system is on the table for the same lock body.
19) Is there an electronic or keypad deadbolt I can use instead of the Arrow N44 mortise deadbolt?
Yes, if you want code or credential access instead of a brass key. The Codelocks CL2210 is an electronic mortise deadbolt, so it keeps the mortise pocket. The Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the CL200 is a light duty surface deadbolt with key override. The Arrow N44 stays the mechanical choice where the deadbolt has to key into an existing Arrow A keyway or small format core system.
