The most common configuration features the NZD Newport lever in 626 Satin Chrome finish.

Corbin Russwin CL3340 NZD 626 – Frequently Asked Questions

1) How does the Corbin Russwin CL3340 patio/privacy lock actually operate on the door?
The CL3340 is ANSI function F77. The latchbolt throws off by lever from either side, the outside lever is locked by a push button, and once locked that outside lever freewheels so it spins without retracting the latch. The inside lever is always free for egress. Because there is no key or emergency override on the outside, it should not be used on a room with no other entrance.
2) Will a Corbin Russwin CL3340 fit a 1-3/8 inch door?
No. The CL3340 covers 1-3/4 inch to 2 inch doors as standard, so a 1-3/8 inch interior door is outside its range. Corbin Russwin lists an option for doors over 2 inch up to 2-1/4 inch. If your leaf is 1-3/8 inch, a Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, though it is a passage function with no privacy button.
3) What backset does the CL3340 cylindrical lever lock use, and can I get it for a wider stile?
Standard is a 2-3/4 inch backset, which is the usual commercial bore spacing and matches most existing 161 preps. Corbin Russwin also lists 3-3/4 inch and 5 inch backsets for wide stile or unusual door prep. The standard latch is a square corner springlatch with a 2-1/4 x 1-1/8 inch front.
4) Can I use the CL3340 on a fire rated door?
The CL3340 carries a fire rating and the CL3300 Series is UL-cUL listed and accepted by the California State Fire Marshal. For a labeled opening you want the optional 3/4 inch throw fire latch rather than the standard 1/2 inch throw springlatch, so specify that when ordering.
5) Is the CL3340 keyed, and can I add a cylinder later?
No cylinder. The CL3340 is a non-keyed patio/privacy function, so there is no keyway on it and nothing to key into a master system. If you need a keyed opening in the same CL3300 chassis and trim, move to a keyed function in the series, which accepts 6 or 7 pin conventional cylinders and all keying levels.
6) If the door does not need to lock at all, what should I order instead of the CL3340?
The CL3340 locks the outside lever by push button; if the opening only needs latching with no locking, a passage function set is the right part. Grade 1 passage levers include the Falcon K101, which covers 1-3/8 inch to 2-1/4 inch doors and is fire rated, the Falcon T101, and the Design Hardware X75 for 1-3/4 inch doors. A Grade 2 passage option is the Arrow GL01 with the Sierra lever for 1-3/4 inch to 2 inch doors.
7) The CL3340 should not be used on a room with no other entrance - what do I use on a single-entry room that still needs privacy?
The CL3340 function note states it should not be used in rooms that have no other exit, since the outside lever locks by push button with no key override. For a single-entry room where staff need outside access, a keyed function is the safer choice: the Dexter C1000 Asylum (F87) is a Grade 1 cylindrical lock for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors.
8) Do I need to worry about handing when I order a CL3340?
No. The CL3340 is non-handed, so one lockset works on a left or right hand door. The only exception Corbin Russwin notes in the CL3300 Series is FZD trim, which is handed. With the Armstrong, Newport and Princeton levers there is nothing to specify for hand.
9) Is the CL3340 strong enough for a high traffic restroom or locker room in a school?
It is a Grade 1 extra heavy-duty cylindrical lockset per ANSI/BHMA A156.2 Series 4000, with a steel chassis that is zinc dichromated for corrosion resistance and independent return springs to stop lever sag. The Lever Release design lets the outside lever spin free when locked, which is what protects the internals when someone forces the handle. That combination is what puts it in schools, healthcare and industrial buildings.
10) What lever styles and finishes can I get on the CL3340 to match the rest of my building?
Three lever designs are offered on the CL3340: Armstrong (AZD), Newport (NZD) and Princeton (PZD). Finishes run from 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613, 613E and 613L oil-rubbed bronzes, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze, plus BSP black suede and WSP white suede powder coat. Newport in 626 satin chrome is the common commercial pick.
11) What is the difference between the CL3340 patio lock and a standard privacy bath lock like the Hager 2540?
The CL3340 is a Grade 1 extra heavy-duty patio/privacy lock with a freewheeling outside lever and no outside override at all. Lighter privacy options sit a grade below: the Hager 2540 is Grade 2 and covers 1-3/8 to 2 inch doors, and the Kwikset 300BRNL Breton privacy lever is Grade 3 for 1-3/8 to 1-3/4 inch residential doors. Use the CL3340 where the traffic and abuse are commercial; use the lighter sets on interior residential or light office doors.
12) Which latch should I pick if my existing door prep has a rounded corner latch face?
Order the 596F68 rounded corner springlatch, 2-1/4 x 1-1/8 inch face on a 2-3/4 inch backset. The default 586F18 is the same size with a square corner front. Matching the corner to what is already routed into the door edge saves recutting the mortise on a retrofit.
13) Is the CL3340 ADA compliant for accessible openings?
The CL3300 Series is listed to ANSI A117.1 accessibility, and the CL3340 uses a lever rather than a knob, which is the operable part requirement on an accessible door. If you are replacing knob privacy sets in a building being brought up to accessibility standards, this is a direct lever swap in a Grade 1 chassis.
14) Will a dummy lever work as a substitute for the CL3340?
No. A dummy trim is a pull only - it has no latch and no locking. The BEST 9K Series 1DT is a Grade 1 non-keyed single dummy trim, the BEST 7KC 1DT is the Grade 2 medium duty equivalent, and the Accentra 455LN Augusta is a Grade 1 single dummy lever. The CL3340 is a working privacy set with a throw-off latchbolt operated by lever and a push button lock on the outside lever, so a dummy only suits the inactive leaf of a pair, not the operating door.
15) I am standardizing a school on Grade 1 cylindrical levers - what covers the classroom doors alongside the CL3340 on restrooms?
The CL3340 handles the privacy and patio openings at Grade 1. For classroom doors, the Dexter C1000 Classroom is a Grade 1 keyed clutching cylindrical lever for 1-3/8 inch to 1-3/4 inch doors, and the C1000 Classroom Security adds the second cylinder for lockdown from inside the room. Corbin Russwin also offers the CL3352 Classroom Intruder double-cylinder function within the same CL3300 family, which keeps chassis and trim consistent across the building.
16) Can I get the CL3300 lockset with an antimicrobial coating or as an electrified lock?
Both exist in the CL3300 Series. MicroShield antimicrobial coating is ordered with suffix option code C. For electric control, the CL33900 electrified option is offered fail safe or fail secure at 12 or 24 VAC/VDC, drawing 250mA at 12V and 150mA at 24V on a continuous duty solenoid, with an ElectroLynx 8-pin connector standard. Note that the CL3340 itself is the non-keyed patio/privacy function, so electrification means moving to the CL33900 version.
17) Can I use a keypad lever set in place of the CL3340 for a restroom or patio door?
Keypad sets solve a different problem. The Lockey 2835 and 2835DC are mechanical pushbutton keyless lever locks with passage function for 1-3/16 inch to 2 inch doors, and the Lockey 1150 is a mechanical keypad lever set for 1-1/8 inch to 2 inch doors - they control who gets in by code rather than giving the occupant a push button privacy lock from inside. The CL3340 is the opposite: inside lever always free, outside lever locked by push button, non-keyed.
