The ND Series is the long-running ANSI/BHMA Grade 1 cylindrical lever lock that most commercial specs default to, and it comes in every common function, lever style and finish, with interchangeable-core options.
Not for: Doors prepped for mortise locks, light-duty residential or closet doors, or buyers who need keyless or electronic access.
AI picks by need
For high-abuse doors prepped for mortise locks
Schlage L9000 Series (line)

Schlage AL Series (line)
A Grade 2 cylindrical lever for offices and low-traffic interior doors where Grade 1 is overkill.

A heavy-duty Grade 1 cylindrical lever line from a major Assa Abloy brand, for facilities standardized on non-Schlage keying.

What the AI looks for in Commercial Locksets & Handles
- ANSI/BHMA grade
- Grade 1 (A156.2 bored or A156.13 mortise) for exterior, school and high-traffic doors; Grade 2 is acceptable for light interior use. The grade reflects cycle and strength testing, and lower grades loosen and sag quickly on busy doors.
- Lock function
- Match the function to the door: passage, privacy, office/entry, storeroom or classroom. The wrong function either leaves a door unlocked or locks people out, and it usually cannot be changed in the field.
- Door prep and backset
- Confirm cylindrical versus mortise prep, the backset (typically 2-3/4 in for commercial) and door thickness (typically 1-3/4 in). A lock that does not match the existing prep will not install without re-machining the door.
- Fire rating
- Fire-rated doors require UL-listed, positive-latching hardware. Non-listed hardware voids the rating of the opening and fails inspection.
- Accessibility
- Use lever trim operable with one hand without tight grasping or twisting. Knobs do not meet ADA requirements on public doors.
- Keyway and core
- Match the facility's existing keyway, or choose small- or full-size interchangeable core if rekeying is frequent. Mixing keyways means extra keys and re-coring costs.
Brands that matter
- Schlage: Allegion's commercial standard; ND, AL and L9000 lines.
- Corbin Russwin: Assa Abloy brand with strong cylindrical and mortise lines.
- Sargent: Assa Abloy brand; the 10 Line and 8200 mortise are common in specs.
- Best: Known for small-format interchangeable core systems.
- Yale: Assa Abloy brand with Grade 1 and Grade 2 commercial levers.
- Falcon: Allegion's value-priced commercial brand.
What to avoid
- Unbranded 'commercial' levers with no stated ANSI/BHMA grade.
- Residential-grade levers on exterior or high-traffic doors.
- Knob trim on doors that must be accessible.
- Non-listed locks on fire-rated doors.
Questions
Cylindrical or mortise?
Buy whichever the door is already prepped for; mortise is tougher but needs a pocketed door edge.
What does finish 626 mean?
It is the BHMA code for satin chrome (US26D), the most common commercial finish.
