Corbin Russwin CL3393-KEYED Service Station Extra Heavy-Duty Cylindrical Lever Lock with Deadlocking Latch

Grade 1 Commercial Cylindrical Lockset with ANSI F92 Service Station Function

The Corbin Russwin CL3393-KEYED is an extra heavy-duty, Grade 1 commercial cylindrical lever lock engineered for demanding service station applications under ANSI function F92. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, this lockset features a throw-off latchbolt operated by lever and a slotted push button that activates a deadlocking latch when pushed in and turned, causing the outside lever to become freewheeling. The outside lever is unlocked by key or by rotating the inside lever once the push button is returned to its original position. Constructed with steel and zinc dichromated components for corrosion resistance, the CL3393 is part of the proven CL3300 Series platform built for years of dependable operation in high-traffic commercial environments.

Corbin Russwin CL3393 NZD 626 – Frequently Asked Questions

1) How does the Corbin Russwin CL3393 service station function actually work day to day?
The CL3393 uses a slotted push button on the inside lever. Push it in and turn, and the outside lever goes freewheeling while the deadlocking latch is activated. To unlock the outside lever, either use the key or return the push button to its original position and rotate the inside lever. Inside egress is always by lever. That is ANSI F92, which is what you want on a door someone locks behind them and wants to stay locked until they choose otherwise.
2) Will the Corbin Russwin CL3393 fit a 1-3/8 inch door?
No. The CL3393 is built for 1-3/4 inch to 2 inch doors, with a 2-1/4 inch option available over 2 inches. A 1-3/8 inch door is outside its range, so on older interior wood doors you need a lock rated down to 1-3/8, such as the Falcon K101 Grade 1 cylindrical, which covers 1-3/8 to 2-1/4 inches.
3) Can the CL3393 go on a fire rated door?
Yes, the CL3393 is fire rated and UL-cUL listed. For a labeled opening, order the optional 3/4 inch throw fire latch rather than the standard 1/2 inch throw latchbolt. It also meets ANSI A117.1 accessibility and carries California State Fire Marshal listing.
4) Can I key the CL3393 into my existing Corbin Russwin interchangeable core system?
Yes. Cylinder options include CL6 (less core, LFIC 6-pin) and CL7 (less core, LFIC 7-pin) so you can drop in your own Corbin Russwin cores. If you are not on an IC system, the standard is a conventional 6-pin brass cylinder in the L4 keyway, 0-bitted. There is also an LC option for less conventional cylinder if your locksmith is supplying it. Keying is ordered keyed different or keyed alike.
5) Is there a storeroom-function lever I can use instead of the CL3393 on a door that must always stay locked?
The CL3393 service station function lets the outside lever be left unlocked by rotating the inside lever, so it is not a permanently secured opening. For a door that stays locked at all times, the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch thick, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch. Both differ from the CL3393, which is Grade 1 and fits 1-3/4 inch to 2 inch doors on a 2-3/4 inch backset.
6) What is the closest Grade 1 keyed cylindrical lever alternative to the Corbin Russwin CL3393 if the service station function is not required?
The CL3393 is a Grade 1 keyed cylindrical lever lock with the service station function, where pushing and turning the slotted button makes the outside lever freewheel until a key or the inside lever releases it. If a keyed Grade 1 cylindrical lever is needed but the button-controlled service station behavior is not, the Dexter C1000 Series classroom lock is a Grade 1 keyed cylindrical lever lock with a clutching lever design for door thicknesses of 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 classroom security version is a Grade 1 keyed cylindrical lever in the same thickness range with two cylinders instead of one. Both are keyed by cylinder alone, with no pushbutton on the inside lever.
7) Which lever lock should I use for a utility or institutional room instead of a Corbin Russwin CL3393?
The CL3393 carries the ANSI F92 service station function on a Grade 1 cylindrical chassis. For an asylum, institution, or utility opening where both sides are meant to be key-controlled, the Dexter C1000 Series asylum lock is a Grade 1 cylindrical lock with the asylum/institution/utility function (ANSI F87) for doors 1-3/8 inch to 2 inch thick. The Arrow MK33-BD-CS is also an asylum/institution/utility function cylindrical lock, Grade 2, with a ball knob rather than a lever and a conventional Schlage C keyway cylinder.
8) My door is thinner than 1-3/4 inch, so the CL3393 will not fit. What lever lock works instead?
The CL3393 is built for doors 1-3/4 inch to 2 inch thick on a 2-3/4 inch backset. On a thinner door, the Falcon K101 covers 1-3/8 inch to 2-1/4 inch as a Grade 1 fire rated passage lever, the Dexter C1000 Series asylum lock covers 1-3/8 inch to 2 inch as a Grade 1 keyed cylindrical lock, and the Hager 2510 covers 1-3/8 inch to 2 inch as a Grade 2 passage lever with the Withnell design. Match the function to the opening, since these cover different functions than the CL3393's service station.
9) What classroom lever should I order instead of a CL3393 for a school corridor door?
A classroom opening is normally keyed from the outside with free egress rather than held by a pushbutton. The Dexter C1000 Series classroom lock is a Grade 1 keyed clutching cylindrical lever for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 classroom security version adds a second cylinder in the same size range so the door can be secured from inside. The Cal-Royal AG03 is a classroom lever from the AG Series with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, matching the CL3393's 2-3/4 inch backset prep.
10) Do I have to specify handing when I order a CL3393?
No handing to specify. The CL3393 is non-handed, so one lock covers left and right hand openings. The only exception in the CL3300 Series is FZD trim. That matters for property managers stocking spares: one part number covers every door in the building.
11) Is the CL3393 tough enough for a high-abuse public door?
It is Grade 1 under ANSI/BHMA A156.2 Series 4000, extra heavy duty, with a steel chassis that is zinc dichromated for corrosion resistance. The Lever Release design lets the outside lever spin free when locked, so someone hanging on the lever is not transferring force into the chassis, and independent return springs stop the lever sagging over time. Anti-rotational through-bolts at 6 and 12 o'clock hold the trim tight to the door.
12) Can the CL3393 be electrified for access control?
Not the CL3393 itself. The electrified version of the platform is the CL33900 Series, available fail safe or fail secure at 12 or 24VAC/VDC, drawing 250mA at 12V and 150mA at 24V on a continuous duty solenoid, with an ElectroLynx 8-pin connector. If the opening ties into a card reader or a fire alarm release, specify the CL33900 rather than the mechanical CL3393.
13) Can I get a rounded corner latch face instead of square for the CL3393?
Yes. The standard is the 586F17 square corner deadlatch, 2-1/4 x 1-1/8 inches at 2-3/4 backset. Order the 596F67 for a rounded corner front at the same size and backset. Match it to the existing mortise in the door edge so you are not patching or routing on a retrofit.
14) What non-keyed Grade 1 lever matches the CL3393 chassis grade for the passage doors on the same job?
For corridor or closet doors on the same project that need no key, Grade 1 non-keyed cylindrical levers include the Falcon K101, a Grade 1 heavy-duty passage lever that is fire rated and fits doors 1-3/8 inch to 2-1/4 inch; the Falcon T101, a Grade 1 heavy-duty passage lever with pressure release technology; the Dexter C1000 passage lock, a Grade 1 clutching non-keyed lever for 1-3/8 inch to 1-3/4 inch doors; and the Design Hardware X75, a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. The CL3393 itself is keyed with a single cylinder and is heavy duty Grade 1.
15) Can I put a dummy lever on the inactive leaf of a pair and still match a CL3393 opening?
A dummy trim is the usual choice for an inactive leaf or a pull-only door, since it has no latch and no chassis. Grade 1 options include the BEST 9K Series 1DT single dummy trim cylindrical lever, a heavy duty non-keyed dummy, and the Accentra 455LN Augusta from the 5400 Series, a Grade 1 heavy duty single dummy cylindrical lever. The BEST 7KC Series single dummy trim is a Grade 2 medium duty version of the same idea. None of these latch or key, so they do not replace the CL3393, which is a keyed Grade 1 lock with a deadlatch.
16) Is the Arrow MK02-TA a substitute for the Corbin Russwin CL3393?
No. The Arrow MK02-TA is a privacy/bed/bath function lock with a Tudor knob and is non-keyed, though it is fire rated. The CL3393 is a keyed single-cylinder lever lock with the service station function, where the slotted push button makes the outside lever freewheel until released by key or by the inside lever. A privacy set has no cylinder, so it cannot serve an opening that requires key control, and a knob does not meet the same operation style as the CL3393's lever trim.
17) What is a simpler keyed entry lever to use instead of a CL3393 on an office door?
For an office door where the only requirement is a keyed outside lever with a pushbutton or thumbturn to hold it unlocked, the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with the entry/office function, and the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle for doors 1-3/8 inch to 2 inch. The Cal-Royal AG00 entrance lever comes with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors. The CL3393 differs in being Grade 1 heavy duty with a 2-3/4 inch backset and a 6-pin L4 keyway cylinder.
18) Can I use a keypad lever in place of a CL3393 to avoid issuing keys?
Keyless lever sets remove the cylinder from the equation entirely. The Lockey 2835 is a mechanical pushbutton keyless lever lock with a passage function and ADA compliance for doors 1-3/16 inch to 2 inch, the Lockey 2835DC adds a double combination in the same thickness range, and the Lockey 1150 is a heavy duty mechanical keypad lever set with a passage function for doors 1-1/8 inch to 2 inch. The Delaney LP250 is an electronic keypad leverlock rated Grade 2. None of these carry the CL3393's ANSI F92 service station function or its 6-pin L4 keyway cylinder, so they are a change in credential, not a like-for-like swap.
19) Are residential-grade levers like Kwikset or Baldwin an acceptable substitute for a CL3393 in a commercial building?
They serve different openings. The CL3393 is a commercial Grade 1 heavy duty cylindrical lever lock built on a steel, zinc dichromated chassis for corrosion resistance. The Kwikset 200BRNL Breton passage lever is Grade 3 for doors 1-3/8 inch to 1-3/4 inch and the Kwikset 300BRNL Breton privacy lever is Grade 3 in the same thickness range, while the Baldwin Estate 5103 is offered in passage, privacy, and half dummy versions. None of those carry a Grade 1 rating or the CL3393's keyed service station function, so for a commercial opening specified at Grade 1 they are not an equal swap.
20) If I standardize on the CL3393 keyway, what happens with locks that come in a Schlage C keyway?
The CL3393 ships with a conventional 6-pin cylinder in the L4 keyway and can also be ordered less cylinder or less core for Corbin Russwin 6-pin or 7-pin large format interchangeable cores. Locks supplied in a Schlage C keyway, such as the Cal-Royal AG00 entrance lever, the Cal-Royal AG03 classroom lever, and the Arrow MK33-BD-CS asylum lock, will not key into an L4 system as shipped. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, which addresses Yale products rather than Corbin Russwin.
21) What lever styles and finishes can I get on the CL3393 to match the rest of my building?
Three cast lever designs are offered on the keyed CL3393: AZD Armstrong, NZD Newport, and PZD Princeton. Finishes run from 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 and 613E and 613L oil-rubbed and dark oxidized bronze, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze oil-rubbed, plus BSP black suede and WSP white suede powder coat. 626 satin chrome is the usual commercial default.
22) I need a matching passage or dummy lever on the adjacent doors. What pairs with the CL3393 look?
Within the CL3300 Series the same Armstrong, Newport, and Princeton lever designs and the same finish range carry across functions, so you can match trim on non-keyed openings. If you are just filling a Grade 1 dummy opening and do not need the Corbin trim to match, the BEST 9K Series 1DT single dummy trim is a heavy duty Grade 1 option, and the Design Hardware X75 is a Grade 1 passage lever for 1-3/4 inch doors.
23) Is there an antimicrobial option on the CL3393 for a healthcare or food service door?
Yes, MicroShield antimicrobial coating is available on the CL3300 Series using suffix option code C. That is worth specifying on patient room, exam room, and kitchen doors where the lever gets touched constantly.
