Schlage ND Series Overview

The Schlage ND Series covers a full range of commercial lock options across mechanical, electrified, and electronic configurations. ND Series locks are tested to withstand 3,100 in-lb. of abusive lever torque, more than 2-1/2 times the Grade 1 standard requirement. Offset lever pull testing up to 1,600 lbs. provides resistance against pry bar attacks. The lock shows near zero droop or wobble after 16 million cycles.

All ND Series locks use the common cylindrical ANSI 161 door preparation, making them interchangeable across mechanical, electrified, and electronic trim. Suitable for new construction and retrofit applications.

Schlage ND82PD RHO 626 – Frequently Asked Questions

1) What does the Schlage ND82 lock function actually do, and is it legal on an exit door?

Both levers stay fixed at all times on the ND82, and the only way through is a key from either side. That is the ANSI F87 asylum/institution/utility function, a double cylinder arrangement. Because nobody can get out without a key, it should not go on a residential door or on any door used for egress in any building; that is a life safety hazard in an emergency. Use it on utility rooms, mechanical spaces, and institutional openings where code allows key-both-sides, and confirm against your local code before you specify it.

2) Will a Schlage ND82 fit my door, and what backset and prep does it need?

The ND82 is built for a 1-3/4 inch door and uses the standard cylindrical ANSI 161 door prep, so it drops into an opening already bored for a commercial cylindrical lock. The standard latch is the 13-247 deadlatch on a 2-3/4 inch backset with a 1-1/8 x 2-1/4 inch square corner faceplate. It is non-handed, so you do not specify hand when ordering. If your existing bore is on a 2-3/8 inch backset, the standard latch will not reach the strike.

3) Will the ND82 latch into the strike that's already in my frame?

The lock ships with the 10-025 ANSI strike, 1-1/4 x 4-7/8 inches with a 1-3/16 inch lip length and no box. If your frame is already cut for an ANSI 4-7/8 inch strike, which is the normal commercial frame prep, the supplied strike drops straight into that cutout. Frames prepped for a small T-strike or a residential full-lip strike will need the opening enlarged. Watch the lip length too: 1-3/16 inch suits a flush frame, and a deeper reveal or applied stop wants a longer lip so the latch is not catching the edge.

4) Which cylinder option should I order on a Schlage ND82, and what if my building is on small format interchangeable core?

Four cylinder choices, and since the ND82 is keyed on both sides the choice applies to both. PD is the conventional 6-pin cylinder in the Schlage C keyway, supplied with two nickel silver cut keys per lock, keyed different unless you order keyed alike. BD gives you the SFIC housing less the core, so your locksmith drops in the cores your facility already runs. JD is the Schlage full size interchangeable core prep, less core. LD is less cylinder entirely, for shops that supply their own. If you are standardized on an SFIC system, order BD and pin your own cores rather than taking PD and rekeying.

5) Does the Schlage ND82 meet ADA and can it go on a fire rated door?

ADA requirements are met, and the lock complies with ICC A117.1 for accessible and usable buildings. It is UL and cUL listed for 3 hour A label single fire doors up to 4 ft x 10 ft, and for 8 ft x 8 ft pairs at 3 hours or 8 ft x 10 ft pairs at 90 minutes with the 3/4 inch latch option. It also meets the Buy American Act and federal FF-H-106C Series 161. For California fire code, the levers with a 1/2 inch or less return to door comply: Rhodes, Sparta, Tubular, Omega, Longitude and Boardwalk.

6) What is the difference between the Schlage ND82 and an ND80 storeroom lock?

The ND80 storeroom function, ANSI F86, keeps the outside lever locked and the inside lever always free to exit. The ND82 has no free side: both levers are fixed and a key is needed from either direction. Storeroom is what you want on almost any door people occupy or pass through, because egress is unimpeded. The ND82 is only for the narrow case where the room must be secured against exit as well as entry, such as a utility or institutional application, and where code permits it. Both share the same Grade 1 ND chassis and the same ANSI 161 prep, so switching between them later is a chassis swap, not a door rework.

7) What else could I buy instead of a Schlage ND82 asylum lock?

The closest cross-brand equivalent ZenSupply carries is the Dexter C1000 Series asylum lock, also Grade 1 F87 function, and it is listed for a 1-3/8 to 2 inch door thickness range rather than the ND82's single 1-3/4 inch. If your openings vary in thickness, that range matters. Arrow's MK33-BD-CS is another asylum/institution function lock, heavy duty, with a conventional cylinder in the Schlage C keyway, though it is a ball knob rather than a lever, so it will not satisfy an accessibility requirement the way a lever does.

8) My doors are thicker than 1-3/4 inches. Can I still use a Schlage ND82?

No. The ND82 is specified at a 1-3/4 inch door thickness, which is the standard commercial door. For an opening at 2 inches or a thin 1-3/8 inch door, look at a lock published with a range: the Dexter C1000 asylum lock covers 1-3/8 to 2 inches for the same F87 function, and the Falcon K101 Grade 1 cylindrical covers 1-3/8 to 2-1/4 inches, though that one is a passage function with no keying at all.

9) Can I put a Schlage ND82 in place of an existing cylindrical lock without redoing the door?

In most cases yes. Every ND Series lock, including the electronic and ligature resistant trim versions, uses the common cylindrical ANSI 161 door preparation, so they are interchangeable with each other and go into new construction or retrofit openings alike. What you need to confirm on the door in front of you is the 2-3/4 inch backset for the standard 13-247 latch, the 1-3/4 inch thickness, and that the frame is cut for the 4-7/8 inch ANSI strike.

10) The double cylinder function is not allowed on my egress door - what Grade 1 lever should I use instead?

For an egress opening, a storeroom or classroom function is the usual substitution. The Dexter C1000 Series classroom lever is Grade 1, keyed and clutching, for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 classroom security model is Grade 1 in the same thickness range. Within the Schlage ND family, the ND80 is the ANSI F86 storeroom function and the ND70 is the ANSI F84 classroom function. The ND82 keys from both sides with both levers fixed, which is why it is not recommended on doors used for egress.

11) Can I get several ND82 locks keyed alike on one key?

Keying is a required selection. Keyed different is standard, so each lock arrives on its own key with two cut keys. Choosing keyed alike puts a group of locks on one key, which is what you want when a maintenance crew carries a single key for a run of utility or mechanical rooms. There is also a free text field for special cylinder and keying requirements if the locks need to go onto an existing master system. Selecting no keying is how you order the less cylinder configurations.

12) Is a Schlage ND82 tough enough for a high abuse institutional opening?

This is heavy duty, ANSI/BHMA A156.2 Series 4000 Grade 1 certified, in zinc and steel. Schlage rates the ND chassis to hold at 3,100 in-lb of abusive lever torque, resist 1,600 lbs of offset lever pull against pry bar attack, and take 100 vertical lever impacts without granting access. Cycle life is 16 million with near zero lever droop and no set screws or O-rings holding the lever on. Those beyond Grade 1 numbers apply with Schlage cylinders; with a non-Schlage cylinder the lock still exceeds BHMA Grade 1 but performance may be lower.

13) Which lever style and finish should I pick to match the other Schlage locks in my building?

Nine lever designs are offered: Athens, Boardwalk, Broadway, Latitude, Longitude, Omega, Rhodes, Sparta and Tubular. Finishes run to ten: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial, and 643E aged bronze. Match the lever and finish already on your other openings and the ND82 blends into the run. 626 satin chrome is the usual commercial default, and 626AM is the same look with an antimicrobial finish for healthcare corridors. If your facility is under California fire code, note that only some of the lever designs qualify.

14) Does the ND82 accept non-Schlage cylinders if my building is keyed to another manufacturer?

Three spring cage sets are offered across the ND Series, supporting all Schlage cylinder formats plus eight competitive cylinder formats. That is how you get an ND82 onto an existing key system from another manufacturer. Be aware of the tradeoff: the beyond Grade 1 strength figures Schlage publishes apply to locks with Schlage cylinders (conventional, FSIC and SFIC), and with a non-Schlage cylinder the lock still exceeds BHMA Grade 1 but the performance may be lower.

15) What is the difference between a Schlage ND82 and a Corbin Russwin CL3110?

Function, not grade. Both are Grade 1 cylindrical lever locks, and the Corbin Russwin CL3110 is fire rated with a 1-3/4 inch to 2 inch door thickness range. The CL3110 is a passage/closet lock in the CL3100 Series, so it is non-keyed and the levers always retract the latch. The Schlage ND82 is keyed, with a double cylinder keyed function and both levers fixed. If a door needs to stay secured from both sides, the CL3110 does not do that job.

16) Can a Falcon K101 or T101 be used in place of a Schlage ND82?

Only where the opening does not need to lock. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock, fire rated, non-handed, with a 1-3/8 inch to 2-1/4 inch door thickness range, and the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology. Both are passage function and non-keyed. The Schlage ND82 is a heavy duty Grade 1 keyed lock in the asylum, institution and utility function, also non-handed. Same grade and duty class, different job.

17) I need a storeroom lever on a budget for a utility room - what are the options against a Schlage ND82?

The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. Both are storeroom function, so the outside lever stays locked and a key retracts the latch from outside only. The Schlage ND82 is Grade 1 with a key required from either side, which is what an asylum or utility function calls for when the room has to stay controlled from both directions.

18) Which Grade 1 lever locks work with small format interchangeable cores like a Schlage ND82 BD?

The BEST 9K Series is the direct SFIC family peer - the 9K 1DT single dummy trim is a Grade 1 heavy duty cylindrical lever in that series, though the dummy has no chassis and no keying. The Schlage ND82 handles interchangeable cores through its cylinder options: BD is furnished less SFIC cylinder and JD is a Schlage FSIC prep less core, with LD less cylinder and PD a conventional 6-pin in the Schlage C keyway. Ordering BD or JD means the core is supplied separately by whoever holds the key system.

19) What looks like a substitute for a Schlage ND82 but will not work on an institutional door?

Dummy trims and residential-grade levers. The BEST 7KC Series single dummy trim is Grade 2 medium duty and the Accentra 455LN Augusta is a Grade 1 single dummy - both are dummy function with no latch and no locking. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever. The Schlage ND82 is a commercial Grade 1 heavy duty keyed lock in zinc and steel. A Grade 3 lever will not hold up to institutional traffic and a dummy will not secure anything.

20) If the opening needs electric access control instead of a mechanical double cylinder lock, what replaces a Schlage ND82?

The Corbin Russwin CL33903 is the electrified peer - a Grade 1 fail safe electrified cylindrical lever lock operating on 12V AC/DC, for doors 1-3/4 inch to 2 inch, offered with the NZ lever and D rose. The Schlage ND82 is a mechanical lock with no electronic option, keyed from both sides. Schlage's own electrified route is within the ND Series, which carries four electrified functions that auto-detect 12/24V DC with a 0.4 amp maximum draw.

21) Can Yale or Accentra hardware be keyed to the same Schlage key as an ND82?

The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, Grade 1, which is how Yale-branded hardware gets brought onto a Schlage cylinder. The Schlage ND82 in the PD configuration ships with a conventional 6-pin cylinder in the Schlage C keyway and takes S123 cylinders and keyways, and can be ordered keyed alike across multiple locks. That combination is what lets a mixed-brand facility run one key system.

22) Will Schlage ND82 locks match the exit devices and Grade 2 locks elsewhere in my building?

Aesthetically, yes. The ND Series lever and rose designs suite with Von Duprin exit devices and other Schlage products, and they are matched to the Schlage ALX Series Grade 2 locks. That is the usual pattern in a mixed facility: ND Grade 1 on the high traffic and institutional openings, ALX Grade 2 on the lighter interior doors, same lever design and same finish throughout so the building reads as one specification.

23) Is a Design Hardware X75 the same class of lever as a Schlage ND82?

Same grade, different function. The Design Hardware X75 is a Grade 1 passage lever lockset in the X Series with a flat lever, built for 1-3/4 inch doors; the Design Hardware J75 is the Grade 2 version of that passage lever, also for 1-3/4 inch doors. The Schlage ND82 is Grade 1 and also sized around a 1-3/4 inch door, but it is a keyed cylindrical lock with two keys supplied per lock and nine lever designs including Athens, Rhodes, Sparta, Omega and Tubular. The X75 latches the door; it does not key it.
