Corbin Russwin CL3300/CL3500 Commercial Locks
Corbin Russwin's Grade 1 cylindrical lever lock lineup — CL3300 (standard Grade 1) and CL3500 (institutional vandal-resistant). Trusted in healthcare, K-12 education, detention, and psychiatric facilities where abuse resistance and patented key control matter more than up-front cost.
Parent company: ASSA ABLOY (Corbin Russwin, Inc.)
About Corbin Russwin CL3300/CL3500
The Corbin Russwin CL3300 and CL3500 Series are ASSA ABLOY's Grade 1 cylindrical lever locks, built for the same high-traffic institutional environments that drive ML2000 mortise lock specifications. Every CL3300/CL3500 is ANSI/BHMA A156.2 Series 4000 Grade 1 certified and UL Listed for 3-hour A-label fire doors. The chassis uses heavy-gauge steel with a reinforced 4-bearing design that reduces drag and wear over long service life.
The key distinction between the two series is abuse resistance. The CL3300 is Corbin Russwin's standard Grade 1 spec — strong commercial lock for offices, classrooms, healthcare corridors, and general institutional use. The CL3500 adds vandal-resistant trim, reinforced internal components, and optional anti-ligature lever designs for detention, psychiatric, and high-abuse environments where the standard CL3300 won't survive. Facilities managing behavioral health units, correctional facilities, and K-12 special education spaces default to the CL3500 — it's one of the few cylindrical locks with certified anti-ligature designs paired with UL fire rating.
Where the CL3300/CL3500 really stands apart is keying depth. Standard Corbin Russwin 59A1 and 60 keyways, upgrade paths to Access 3® (patented, dealer-restricted) and Pyramid (top-tier high-security with side-bit milling, UL437 equivalent). For multi-building campuses with existing Corbin Russwin master key systems — common in universities, hospital systems, and government — the CL3300/CL3500 slots into the existing keyway without fragmenting the master plan. Also available with SFIC and CR LFIC interchangeable core housings for facility-managed rekeys. Key-En-Lock is a factory-authorized Corbin Russwin dealer for Access 3 and Pyramid rekeys and services the full CL3300/CL3500 lineup across Brevard County.

What's the difference between CL3300 and CL3500?
The CL3300 is Corbin Russwin's standard Grade 1 cylindrical — strong commercial lock for offices, classrooms, healthcare corridors, general institutional. The CL3500 adds vandal-resistant trim, reinforced internal components, and anti-ligature lever options (BHSS, HSS) for detention, psychiatric, and abuse-prone environments. Both share the same lockbody dimensions and keyway systems, so you can mix them in the same building on different openings. Rule of thumb: low-abuse interior office → CL3300. Detention, psychiatric, K-12 special education, repeat-vandalism exterior → CL3500.
Why would I spec CL3300 over Schlage ND or Best 9K?
Three reasons drive CL3300 specification. First, existing Corbin Russwin master key systems — if your building portfolio is already on CR 59A1, 60, Access 3®, or Pyramid keyways, adding CL3300 locks keeps you on one master plan. Second, institutional trim options — Corbin Russwin has the deepest cylindrical lock trim catalog for healthcare and behavioral health environments, with UL-listed anti-ligature options other brands don't match. Third, ML2000 mortise pairing — if you spec ML2000 mortise locks on entry doors and need cylindrical for interior, the CL3300 shares keyway and trim design so the building has visual and operational consistency.
Is CL3500 really anti-ligature certified?
Yes. Corbin Russwin's BHSS (Behavioral Health Integrated) lever and HSS (Anti-Harm Knob) trim options are specifically designed to eliminate ligature points — the recessed, tapered designs prevent attachment of ropes, cords, or fabric that could be used for self-harm. These trim options are certified for psychiatric facilities and detention environments, and they retain UL 3-hour fire rating (a rare combination — most anti-ligature hardware sacrifices fire rating). For Florida behavioral health certifications and DCF-licensed psychiatric facilities, CL3500 with BHSS or HSS trim is one of the few cylindrical options that passes all three certifications simultaneously.
Can I rekey CL3300 to match my existing building key system?
Yes, in almost all cases. If your building uses standard 6-pin keyways (Schlage C, Kwikset KW, Sargent LA, Best A2, Yale GA), we can rekey the CL3300 cylinder on-site to match. If your building uses patented Corbin Russwin keyways (Access 3, Pyramid), we're factory-authorized for both and handle rekeys directly. The only constraint: Access 3 and Pyramid blanks are dealer-restricted, so the replacement cylinder must come from a CR authorized dealer (we are one). For non-patented keyways, rekey is straightforward.
How does CL3300 compare to the ML2000 mortise lock in the same Corbin Russwin lineup?
CL3300 is a cylindrical lock (standard bored door prep, ~10 functions, no integrated deadbolt, 10-15 year service life). ML2000 is a mortise lock (rectangular pocket in door edge, 63 functions, integrated 1" deadbolt, 15-20+ year service life). Specification choice depends on the door: entry doors, high-traffic corridors, and hospital patient rooms typically spec ML2000 mortise. Interior office doors, classrooms, utility rooms, and storeroom doors typically spec CL3300 cylindrical. Both share the same Corbin Russwin keyway options (59A1, 60, Access 3, Pyramid) so they master-key together cleanly.
Is CL3375 F110 code-compliant for Florida K-12 classroom security?
Yes. The CL3375 (F110 classroom security) meets current Florida school hardware requirements. Key in either lever locks/unlocks the outside — teacher locks from inside without opening the door during lockdown. Inside lever always free under NFPA 101. UL 3-hour fire rating. For extra abuse resistance on K-12 special education or alternative-ed classrooms, the CL3575 variant adds CL3500 vandal-resistant trim.
Are Corbin Russwin and Sargent interchangeable since both are ASSA ABLOY?
Both are ASSA ABLOY brands but operate as separate businesses with distinct product lines, keying systems, and dealer networks. A Corbin Russwin 59A1 cylinder does NOT fit a Sargent housing and vice versa. Keyways are not cross-compatible. ASSA ABLOY maintains both brands so specifiers and end-users can pick based on existing building key systems, dealer relationships, and regional preference. Both brands share the parent company for corporate resources but the products do not interoperate at the hardware level.
