ND91 - VANDLGARD ENTRANCE/OFFICE LOCK

Push-button locking. Push-button disengages outside lever until unlocked with key or by turning inside lever.


Schlage ND SERIES OVERVIEW

The Schlage ND Series offers a full breadth of commercial lock options with a suited combination of mechanical, electrified and electronic options. This overview covers common characteristics for the mechanical and electrified lock information.

Beyond grade 1 performance is the hallmark of the mechanical and electrified locks. 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. assures you of the lock's superb resistance against pry bar attacks. More than strong, ND Series is built to last and shows nearly zero droop or wobble after 16 million cycles.

All ND Series locks including electronic and ligature-resistant trim use the common cylindrical ANSI 161 door preparation making them easily interchangeable. They are ideal for all new construction and retrofit applications.


ND Series Mechanical Lock

The ND mechanical lock, along with being Schlage’s best selling mechanical lock, is the foundation for both the wired electrified and NDE wireless electronic lock. Not only did Schlage invent the cylindrical lock, but they continue to make it better with capabilities such as:

  • Unparalleled strength - the lock prevents access even when subjected to torque loads up to 3,100 in-lbs (2.6x BHMA1), withstands pry bar attacks of 1,600 lbs (8x BHMA requirements1), and withstands 100 hammer blows (20x BHMA requirements1, 2)
  • Exceptional durability - cycle tested to over 16M cycles (16x BHMA requirements1) with near zero droop or wobble - without the use of set screws or O-rings
  • Improved feel - improved strength and durability are more than numbers, you can actually feel it in the lock
  • Improved installation - installation is even easier than before (and withoutany set screws or O-rings)


FEATURES & BENEFITS

Security

  • Significantly exceeds ANSI/BHMA Grade 1 requirements
  • No access with minimum 3,100 in-lb. abusive lever torque, the equivalent of over 690 lbs. applied to the end of a 4-1/2" lever, 2.6 times over the BHMA requirement*
  • No access with minimum 1,600 lbs. offset lever pull for protection against pry bar attacks, 8 times over the BHMA requirement*
  • 5 points of engagement provide nearly zero droop and wobble after 16 million cycles, 16 times over the BHMA requirement*, without the use of set screws or o-rings
  • High security locking when used with Primus XP UL 437 listed cylinders

Function availability and convenience

  • 24 mechanical/4 electrified functions in the ND Series (custom functions available upon request)
  • Multiple key systems available: open, patented and restricted
  • Four electrified functions auto-detect 12/24V DC operation and, with maximum current draws of 0.4 amps and 0.1 amps holding current eliminate heated levers
  • Indicator roses for classroom applications
  • Three spring cage sets support all Schlage plus eight competitive cylinder formats

Aesthetics

  • Nine lever and four rose designs
  • Ten available finishes
  • Perfectly suited to Schlage ALX Series grade 2 locks
  • Suites with Von Duprin exit devices and other Schlage products

Options

  • Vandlgard™ models have a lever that freely rotates up and down when locked to protect the chassis from excessive force on the lever to prevent vandlism.

*Beyond Grade 1 performance for ND Series locks with Schlage cylinders only (Conventional, FSIC & SFIC). Performance with non-Schlage cylinders will exceed BHMA grade 1 requirements, but the product performance may be less than that of Schlage cylinders.

Schlage ND91PD-RHO-626 – Frequently Asked Questions

1) What does the Schlage ND91 Vandlgard entrance/office function actually do at the door?
The ND91 is a push-button entrance/office lock. Pushing the button on the inside locks the outside lever; it stays locked until a key is used outside or the inside lever is turned, which releases the button. Because it's a Vandlgard model, the outside lever spins freely up and down when locked instead of taking the load, so someone hanging on the lever doesn't break the chassis. That is the difference between the ND91 and a plain ND50 entrance/office lock: same F82 function, vandal-resistant trim.
2) Will a Schlage ND91 fit my existing door prep and 2-3/4 inch backset?
Yes, if the door is bored to the standard cylindrical ANSI 161 prep. The ND91 ships with the 13-247 deadlatch on a 2-3/4 inch backset with a 1-1/8 x 2-1/4 inch square corner faceplate, and the 10-025 ANSI strike, no box, 1-1/4 x 4-7/8 inches with a 1-3/16 inch lip. All ND Series locks share that ANSI 161 prep, so replacing another ND with this one is a straight swap. If your existing openings are bored at 2-3/8 inch backset, this standard latch will not reach.
3) What door thickness does the Schlage ND91 lever lock cover?
1-3/4 inches, the standard commercial door thickness. That's the thickness the ND91 is supplied for as standard. If you're hanging hardware on thicker doors, this is not the lock to spec off the shelf.
4) Do I need to order the Schlage ND91 handed for a left or right hand door?
No. The ND91 is non-handed, so one lock covers both swings. That matters if you're buying for a building with mixed handing, since you can stock a single part number and not sort levers on site.
5) Can I get Schlage ND91 locks keyed alike across a building, and what keyway do they use?
Yes. Keying is a required selection: keyed different, keyed alike for multiple locks, or no keying if you're ordering less cylinder. The standard cylinder is the P conventional 6-pin in the Schlage C keyway, and two nickel silver cut keys come with each lock. If you already have a master key system, you can also order the lock less cylinder in three ways: B less SFIC, J less FSIC, or L less cylinder, and drop in your own. Schlage's spring cage sets support Schlage formats plus eight competitive cylinder formats, so the ND91 can be brought into an existing non-Schlage key system.
6) Is the Schlage ND91 approved for a fire rated door?
Yes. ND Series locks are UL and cUL listed for 3 hour A label single fire doors up to 4'0" x 10'0", and for pair doors at 3 hour up to 8'0" x 8'0" with the 3/4 inch latch option, or 90 minute up to 8'0" x 10'0" with the same 3/4 inch latch. Note the pair door listings depend on the 3/4 inch latch, not the standard latch, so specify it when the opening is a fire rated pair.
7) Does the Schlage ND91 meet ADA and accessibility code for a school or healthcare facility?
The ND91 meets ADA requirements and complies with ICC A117.1 for accessible and usable buildings. It's certified under ANSI/BHMA A156.2 Series 4000 Grade 1 and meets the Buy American Act, which matters on federally funded work, plus federal spec FF-H-106C Series 161. For California, levers with a return to door of 1/2 inch or less comply, and that covers the Rhodes, Sparta, Tubular, Omega, Longitude and Boardwalk levers.
8) Should I use an ND91 entrance/office lock or a storeroom or classroom function on this door?
Pick by who controls the lock. Entrance/office (F82) lets an occupant lock the outside lever from inside with the push button, which suits private offices, break rooms and suite doors. If the door must always be locked outside and key only, with the inside lever always free to exit, that's the ND80 storeroom (F86). If a teacher needs to lock and unlock the outside lever with a key from the corridor, that's the ND70 classroom (F84). Non-keyed openings take ND10 passage (F75) or ND40 privacy (F76). All of those share the same ANSI 161 prep as the ND91, so you can change function later without touching the door.
9) What is the closest Grade 1 cylindrical entrance/office lever lock to the Schlage ND91?
The Dexter C1000 Series Entry/Office lever (DEX-C1000-ENTR) is the nearest equivalent: it is a Grade 1 keyed cylindrical lever lock with an Entrance/Office function, the same function the Schlage ND91 performs with its push-button locking that disengages the outside lever until unlocked with a key or by turning the inside lever. The Dexter fits doors 1-3/8 inch to 1-3/4 inch, while the ND91 is set up for a 1-3/4 inch door with the 13-247 deadlatch on a 2-3/4 inch backset. The ND91 adds Vandlgard trim, where the outside lever rotates freely when locked instead of transmitting force into the chassis.
10) The opening needs a storeroom lock instead of entrance/office - what takes the place of the ND91?
The Schlage ND91 is an Entrance/Office lock, ANSI F82, where a push button controls whether the outside lever is locked. If the door must stay locked at all times and only open with a key, that is storeroom function. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever fitting doors 1-3/8 inch to 2 inch. Both are storeroom function rather than the push-button entrance/office behavior.
11) If the classroom needs to be locked from inside, is the ND91 the right lock?
No. The Schlage ND91 is an Entrance/Office function lock keyed with a single cylinder, locked by a push button on the inside. For classroom openings, the Dexter C1000 Classroom lever (DEX-C1000-CLRM) is a Grade 1 keyed classroom lock with a clutching lever, and the Dexter C1000 Classroom Security lever (DEX-C1000-CSEC) is the Grade 1 classroom security version; both fit doors 1-3/8 inch to 1-3/4 inch. Cal-Royal's AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway on a 2-3/4 inch backset, which matches the 2-3/4 inch backset the ND91 uses.
12) What looks like a substitute for the ND91 but will not lock the door?
Dummy and passage trim. The BEST 9K Series 1DT is a Grade 1 heavy duty non-keyed single dummy trim cylindrical lever, and the Accentra 455LN Augusta is a Grade 1 dummy cylindrical lever lock; both share the Grade 1 rating and lever format of the Schlage ND91 but have no latch operation and no cylinder. Design Hardware's X75 is a Grade 1 passage lever lockset for a 1-3/4 inch door, which retracts a latch but never locks. The ND91 is a keyed single-cylinder lock that ships with two keys.
13) I want the whole building on the Schlage C keyway - which other levers key to the same system?
The Schlage ND91 uses the S123 cylinder and keyway family and ships standard with the P conventional 6-pin cylinder in the Schlage C keyway, with less-cylinder options for SFIC, FSIC, or no cylinder at all. Among other brands, the Cal-Royal AG00 entrance lever and AG03 classroom lever both carry a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS asylum lock uses a conventional cylinder in the Schlage C keyway. That lets mixed-brand openings sit on one key system.
14) Is the Vandlgard version of the ND worth it over a standard lever for a high abuse opening?
On dorms, schools, and public corridors where people hang on levers, yes. The Vandlgard trim lets the locked outside lever rotate freely so force never reaches the chassis. Underneath, the ND chassis is already tested to 3,100 in-lb of abusive locked lever torque, 1,600 lb offset lever pull against pry bar attack, 100 vertical lever impacts, and 16 million cycles with near zero droop, without set screws or O-rings. On a low traffic private office, a standard non-Vandlgard entrance/office lock covers the same F82 function.
15) What lever styles and finishes can I get on the Schlage ND91?
Nine levers: Athens, Boardwalk, Broadway, Latitude, Longitude, Omega, Rhodes, Sparta and Tubular. Ten finishes: 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. Both sides of the door get the same lever, rose and finish. 626AM is the one to look at for healthcare and food service, and if you're matching California return-to-door compliance, stay with Rhodes, Sparta, Tubular, Omega, Longitude or Boardwalk.
16) Will the Schlage ND91 match the exit devices and other locks already in my building?
The ND Series suites with Von Duprin exit devices and other Schlage products, and it's designed to match Schlage ALX Series Grade 2 locks. That's the usual pattern in a commercial building: ND on the heavy traffic and secured openings, ALX on lighter interior doors, with the same lever design and finish across both. Since every ND uses the same ANSI 161 prep, you can also mix mechanical, electrified and NDE wireless locks on the same doors later without redoing the prep.
17) What is the Grade 1 alternative to the Schlage ND91 if I need vandal resistant lever trim from another brand?
The closest vandal resistant cylindrical lever we carry from another maker is the Corbin Russwin CL3100 Series, listed as Grade 1 vandal resistant and fire rated, for 1-3/4 to 2 inch doors. Note the CL3110 we stock is passage/closet, so it has no cylinder and no locking, unlike the keyed entrance/office ND91. Dexter's C1000 Series carries a Grade 1 entry/office keyed lever for 1-3/8 to 1-3/4 inch doors if you want the same function in a lighter package, but it is not a vandal resistant lever. Falcon's K Series is Grade 1 heavy duty and fire rated for 1-3/8 to 2-1/4 inch doors, useful when the door is thicker than 1-3/4 inches.
18) Can I get higher security keying on the Schlage ND91 for a door that needs key control?
Yes. The ND chassis supports high security locking when used with Primus XP UL 437 listed cylinders, and Schlage offers open, patented and restricted key systems. Order the lock less cylinder (L less cylinder, B less SFIC, or J less FSIC) if your locksmith is supplying the high security cores from your existing system. Standard as supplied is the conventional 6-pin Schlage C keyway.
19) Is the Schlage ND91 an electronic or access control lock?
No, the ND91 is a mechanical single cylinder keyed lock, no electronics. If you need credential access on the same opening, the ND platform carries wired electrified functions that auto-detect 12/24V DC with 0.4 amp maximum draw and 0.1 amp holding current, and the NDE wireless electronic lock. All of them use the same ANSI 161 prep as the ND91, so a mechanical ND91 today can be swapped to an electrified or wireless ND later without new door machining.
20) Is there a lighter-duty entrance/office lever if Grade 1 is more than the door needs?
Yes. The Falcon B511CP6D is a Grade 2, medium duty cylindrical lever lock with an Entrance/Office function, the same function as the Schlage ND91, which is Grade 1 and heavy duty. For low-traffic interior offices the Grade 2 chassis carries the same push-button entrance/office behavior at a medium duty rating; for exterior and high-traffic openings the ND91's heavy duty Grade 1 chassis is the one specified.
21) Do I need a keypad or electrified lever instead of a mechanical entrance/office lock?
The Schlage ND91 is a mechanical, non-electronic lock; access is by key or by the inside lever releasing the push button. If the opening needs code-based entry or remote release, the Lockey 1150 is a mechanical keypad lever set for doors 1-1/8 inch to 2 inch, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Corbin Russwin CL33903 is a Grade 1 fail safe electrified lever running 12VAC/DC for doors 1-3/4 inch to 2 inch. Those change how the door is released; the ND91 changes nothing about the opening beyond standard cylindrical prep.
22) The door is a restroom or bedroom - is the ND91 the right function there?
No. The Schlage ND91 is a keyed Entrance/Office lock with a single cylinder. A restroom or bedroom door wants privacy function, which locks from inside without a key: the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed and fire rated for doors 1-3/4 inch to 2 inch, and the Kwikset 300BRNL RDT Breton is a Grade 3 privacy lever set for doors 1-3/8 inch to 1-3/4 inch. Keep the ND91 for the office and entry doors on the same floor.
23) What is the Schlage ND91 lock body made of, and will it hold up outdoors or in a coastal building?
Zinc and steel construction, rated heavy duty and built for commercial use. The published environmental approvals are structural rather than corrosion related: the ND Series complies with the Florida Building Code under ASTM E330, E1886 and E1996 and with Miami Dade TAS 201, 202 and 203 for hurricane requirements, which is what gets it accepted on exterior openings in those jurisdictions.
24) Is a decorative brass entry lever an alternative to the ND91 on a commercial opening?
They serve different buildings. The Deltana 6201 Manchester and 6431 Linstead are entry-function levers for doors 1-3/8 inch to 2 inch, and the Baldwin Estate 5103 comes in passage, privacy and half dummy versions with the 5048 rose - decorative trim families sized for residential and hospitality doors. The Schlage ND91 is a commercial Grade 1 heavy duty cylindrical lever in zinc and steel, non-handed, offered in nine lever styles including Rhodes, Sparta and Longitude across ten finishes.
