Corbin Russwin CL3320TO Time Out Extra Heavy-Duty Cylindrical Lever Lock, Non-Keyed, Grade 1, 1-3/4" to 2" Doors

Commercial-Grade Time Out Cylindrical Lockset for Institutional and High-Security Applications

The Corbin Russwin CL3320TO is an extra heavy-duty, non-keyed cylindrical lever lock engineered for demanding commercial, industrial, and institutional environments. Designed as part of the CL3300 Series, this Grade 1 lockset delivers the Time Out function: latchbolt operates by lever from either side (passage mode) unless a push button is depressed and held by a caretaker, at which point the detention side lever becomes freewheeling. The lock automatically returns to passage mode upon release of the push button, and both levers remain free at all times. Compatible with door thicknesses of 1-3/4" to 2" and featuring a 2-3/4" backset, the CL3320TO is built on a steel and zinc dichromated substrate for corrosion resistance, and is fire rated for added code compliance.

Professional Features & Benefits

  • Door Thickness Compatibility: Designed for 1-3/4" to 2" doors, accommodating the most common commercial door profiles for broad installation flexibility.

Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness (1-3/4" to 2"), stile width, and handing as applicable to this product.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and/or frame surfaces per ANSI/DHI door prep A115.18.
  3. Prepare door and frame by drilling required holes and routing as specified in manufacturer instructions for the 2-3/4" backset configuration.
  4. Install all mounting hardware and secure the device to door and frame per manufacturer torque specifications using the EZ-Install components provided.
  5. Adjust operational components for proper alignment, latching, and smooth lever operation throughout the full range of motion; verify independent return springs are properly seated to prevent lever sag.
  6. Test Time Out function by depressing push button to confirm detention-side lever freewheels, then release push button to confirm automatic return to passage mode. Refer to manufacturer documentation for complete installation details and troubleshooting.

Corbin Russwin CL3320TO NZD 626 – Frequently Asked Questions

1) What does the Time Out function on the Corbin Russwin CL3320TO actually do?
Both levers stay free at all times, so the door works like a passage set from either side. When a caretaker depresses and holds the push button, the lever on the detention side goes freewheeling and won't retract the latch. Let go of the button and the lock drops straight back to passage mode; the button auto-releases when it isn't held. It's a supervised, momentary restraint function, not a lock you set and walk away from. There is no key and no cylinder on the CL3320TO.
2) Will the CL3320TO fit a 1-3/4 inch commercial door with a 2-3/4 inch backset?
Yes. The CL3320TO covers 1-3/4 inch to 2 inch doors and is built for a 2-3/4 inch backset, which is the standard commercial bore. If your door is a 1-3/8 inch interior leaf, this is the wrong lock, and if your prep is 2-3/8 inch backset it won't line up either.
3) Does the Corbin Russwin CL3320TO drop into an existing ANSI A115.18 door prep?
It does. The CL3320TO is prepped to ANSI/DHI A115.18, so a door already bored for a standard commercial cylindrical lockset at 2-3/4 inch backset takes it without new routing. The springlatch front is 2-1/4 x 1-1/8 inches with a square corner as standard; if your existing edge mortise is radiused, order the 596F66 rounded corner springlatch instead so you aren't re-cutting the door edge.
4) Can a Time Out cylindrical lock go on a fire rated door?
The CL3320TO carries a fire rating, and its latch is a springlatch that keeps the door latched in the frame. That matters on a rated assembly. Note the function keeps both levers free at all times, so egress is never blocked by the lock itself.
5) Is a Time Out lock the right choice, or should I use an asylum or classroom function?
Time Out is for supervised, momentary restraint: the caretaker holds a button and the detention side lever freewheels only for as long as they hold it. Nothing stays locked. If you need a room that stays secured until staff key it open, that's an asylum or institution function, and ZenSupply carries the Dexter C1000 Series Asylum (F87) as a Grade 1 option for 1-3/8 to 2 inch doors, or the Arrow MK33-BD-CS asylum lock with a Schlage C keyway. If the requirement is a classroom that locks from outside with a key, look at the Dexter C1000 Series classroom lever. Pick Time Out only when the intent is temporary hold under direct supervision.
6) What is the closest Grade 1 non-keyed cylindrical lever lock to the Corbin Russwin CL3320TO when the door does not need the Time Out push button?
The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a fire rating, covering doors 1-3/8 inch to 2-1/4 inch. The Corbin Russwin CL3320TO is also Grade 1, heavy duty, non-handed and fire rated, but it carries the Time Out function: the latchbolt is operated by lever from either side unless a push button is depressed and held, at which point the detention side lever freewheels and the lock returns to passage mode when the button is released. If the opening only needs both levers always free with no caretaker override, the K101 covers it; if a caretaker needs to release the detention side lever on demand, the Time Out function of the CL3320TO is what does that.
7) Is an asylum or institution function lock the same thing as a Time Out lock?
They are different functions. The Dexter C1000 Series F87 is a Grade 1 asylum, institution and utility function cylindrical lock for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a heavy duty asylum, institution and utility function lock with a ball knob and a conventional cylinder in the Schlage C keyway. Both are keyed institutional functions. The Corbin Russwin CL3320TO is non-keyed: both levers are always free and the latchbolt operates by lever from either side unless a caretaker depresses and holds a push button, which makes the detention side lever freewheel until the button is released. Specify by how the door has to behave - an asylum function controls the opening with a key, while Time Out controls it with a held push button and no cylinder.
8) Which Grade 1 lever lock do I use if the room needs to be locked with a key rather than held open by a caretaker?
The Corbin Russwin CL3320TO has no cylinder - it is non-keyed, and both levers are always free. For key control on the same class of door, the Dexter C1000 Series offers Grade 1 keyed clutching lever locks in classroom, classroom security, and entry/office functions, all for doors 1-3/8 inch to 1-3/4 inch. 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. Note the CL3320TO covers 1-3/4 inch to 2 inch doors, so check the leaf thickness before swapping to one of the 1-3/4 inch maximum functions.
9) What is the difference between a privacy lever lock and a Time Out lever lock?
A privacy function locks the door from the occupied side. The Arrow MK02-TA is a privacy, bed and bath function non-keyed cylindrical lock with a Tudor knob, rated Grade 1 and fire rated for doors 1-3/4 inch to 2 inch, and the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever. The Corbin Russwin CL3320TO works the opposite way: both levers are always free at all times, and a caretaker outside the room depresses and holds a push button to make the detention side lever freewheel, with the lock returning to passage mode as soon as the button is released. Privacy gives control to the occupant; Time Out gives it to staff and never leaves the room latched shut on its own.
10) Do I need to order a handed version of the CL3320TO?
No handing to specify. The CL3320TO is non-handed, so one part number covers left and right hand openings. What you do have to decide at the order is which side is the detention side, since that is the lever that freewheels when the push button is held.
11) What Grade 1 non-keyed lever can I use on the rest of the doors to match a Time Out installation?
For plain passage openings alongside a CL3320TO run, the Falcon K101 is a Grade 1 heavy duty non-keyed passage lever with a fire rating that spans 1-3/8 to 2-1/4 inch doors, and the Falcon T101 is another Grade 1 heavy duty passage set. The Design Hardware X75 is a Grade 1 passage lever for 1-3/4 inch doors. For a door that needs trim only and no latch, the BEST 9K Series 1DT single dummy trim is Grade 1. None of these carry the Time Out button, so they aren't substitutes on the detention opening itself.
12) Will the CL3320TO hold up in a behavioral health or correctional setting where levers get abused?
It's rated ANSI/BHMA Grade 1 extra heavy duty, the highest commercial grade, on a steel body with a zinc dichromate treatment for corrosion resistance. The CL3300 Series uses a Lever Release design so the outside lever spins free rather than transmitting force into the chassis when someone hangs on it, and independent return springs keep the levers from sagging over time. That combination is what separates it from the Grade 2 and Grade 3 levers in the same shape.
13) What is a lighter-duty alternative to a Grade 1 cylindrical lever lock for a low-traffic non-keyed opening?
For openings that do not carry institutional traffic, the Accentra 5301LN Augusta is a Grade 2 cylindrical lever lock in passage, hall and closet function, and the Falcon B101 is a Grade 2 medium duty non-handed cylindrical passage lever lock. The Hager 2510 is a Grade 2 passage cylindrical lever lock with the Withnell design for doors 1-3/8 inch to 2 inch. All three give both levers always free with no key and no push button. The Corbin Russwin CL3320TO is Grade 1 heavy duty and adds the Time Out push button that makes the detention side lever freewheel while a caretaker holds it - a passage lock has no equivalent to that.
14) What should I use on the inactive leaf or a pull-only door in the same corridor as a Grade 1 lever lock?
A dummy trim carries no latch at all. The BEST 9K Series 1DT is a Grade 1 heavy duty non-keyed single dummy trim cylindrical lever lock, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever lock in the 5400 Series. The BEST 7KC Series single dummy trim is the Grade 2 medium duty version of the same idea. The Corbin Russwin CL3320TO is a working lockset - it ships with a springlatch, square corner front, 2-1/4 inch by 1-1/8 inch on a 2-3/4 inch backset, and an ANSI curved lip strike with 1-1/4 inch lip length. Use the dummy trim where the leaf only needs a pull, and the CL3320TO where the latchbolt has to operate.
15) Will a Grade 3 residential lever hold up on a school or healthcare corridor door?
Grade 3 leversets such as the Kwikset 200BRNL Breton passage, the Callan Asheville passage and the Master Lock BC Series keyed entry are built to a different duty class than the Corbin Russwin CL3320TO, which is ANSI/BHMA Grade 1, heavy duty, commercial, and built on a steel substrate with zinc dichromate for corrosion resistance. The Kwikset 200BRNL also covers doors 1-3/8 inch to 1-3/4 inch, while the CL3320TO covers 1-3/4 inch to 2 inch. For institutional traffic on a fire rated assembly, match the Grade 1 rating and the door thickness the leaf actually measures.
16) Can a keypad or keyless lever lock replace a Time Out lockset on a behavioral health door?
They control the door in different ways. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function for doors 1 3/16 inch to 2 inch, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination and passage function for 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Each of those grants access to whoever enters a code. The Corbin Russwin CL3320TO grants nothing by code: both levers are always free, and the only control is a caretaker holding a push button, which makes the detention side lever freewheel until released. Pick by whether the staff member needs to be at the door with a hand on the button or entering a credential.
17) I need a Grade 1 lever with a 2-3/4 inch backset - which options actually match that prep?
The Corbin Russwin CL3320TO uses a 2-3/4 inch backset with a springlatch, square corner front, 2-1/4 inch by 1-1/8 inch. Among comparable levers, the Cal-Royal AG03 classroom lever is a Grade 2 6-pin Schlage C keyway lock supplied keyed different on a 2-3/4 inch backset, while the Cal-Royal AG00 entrance lever is a 2-3/8 inch backset and would not drop into the same door prep. If the existing cross bore is set at 2-3/4 inch, confirm the backset on the replacement before ordering rather than assuming it follows the series.
18) Is a Grade 1 passage lever from another line a drop-in for a Time Out lock on a 1-3/4 inch door?
Not functionally, even where the grade matches. The Falcon T101 is a Grade 1 heavy duty cylindrical passage lever lock with Pressure Release Technology, and the Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. Both leave the levers free in both directions permanently. The Corbin Russwin CL3320TO adds the push button a caretaker holds to make the detention side lever freewheel, releasing back to passage the moment the button is let go. Where a room requires that momentary staff control, a passage lever does not substitute for it regardless of grade.
19) What lever styles and finishes does the CL3320TO come in for matching existing hardware in a building?
Three lever designs: Armstrong (AZD), Newport (NZD) and Princeton (PZD). Finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 613E and 613L dark oxidized satin 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 institutional standard if you're matching a facility already on BHMA 626.
20) Which lever locks match a decorative interior lever program rather than an institutional one?
The Baldwin Estate 5103 is offered in passage, privacy, and left hand and right hand half dummy functions with the 5048 rose, and the Emtek Classic Brass Cortina and Arts and Crafts leversets come as dummy pairs. Those are decorative interior programs. The Corbin Russwin CL3320TO is a commercial Grade 1 heavy duty lever lock on a steel, zinc dichromated substrate, non-handed, and offered in Armstrong, Newport and Princeton lever designs. Where a project mixes decorative interior doors with institutional corridors, the two programs are specified separately and are not interchangeable trim.
