Corbin Russwin CL33905 NZD 626 M08 12AD – Frequently Asked Questions

1) Will the Corbin Russwin CL33905 electrified leverset fit a 1-3/4 inch door with a 2-3/4 inch backset?
That's exactly the opening it's built for. The CL33905 covers doors from 1-3/4 inch to 2 inch thick and comes standard with a 2-3/4 inch backset, which is the common commercial bore layout. If your doors run thicker than 2 inch, or the prep is a 3-3/4 inch or 5 inch backset, the CL3300 platform has optional door thickness up to 2-1/4 inch and optional 3-3/4 inch and 5 inch backsets, but those are ordered options rather than what ships standard.
2) What happens to a fail secure electrified lever when the power drops?
Power off leaves the outside lever locked. The CL33905 is the fail secure version, so a power loss or an access control failure secures the opening from the outside, while the inside lever stays free at all times for egress. A key in the cylinder still retracts the latchbolt with the power off, so a locksmith or facilities staff can get in without power. If you need the door to release and allow free entry on power loss instead, that's the fail safe version of the CL33900 Series, not this one.
3) Does the CL33905 come with a cylinder, or do I need to supply the core?
No core is included. The CL33905 NZD is ordered less core in two prep styles: a 6-pin LFIC prep with request to exit, or an SFIC prep. You supply the interchangeable core to match the keying system already in the building, which is why locksmiths and facility groups usually spec it this way. The lock is a single cylinder keyed function, and the CL3300 chassis takes 6 or 7-pin conventional cylinders and all keying levels if you go that route instead.
4) What power supply and wiring does the CL33905 electrified lockset need?
It's hard wired at 12VAC/DC drawing 250mA on a continuous duty solenoid, so size the supply and the door loop for a continuous 250mA draw per leaf, not an inrush-only figure. There's no battery in this lock. The connection is an ElectroLynx 8-pin connector, standard across the electrified line, so it plugs into an ElectroLynx electric hinge or power transfer rather than needing field-spliced leads. If your panel run is long enough that 12V drop is a concern, the CL33900 Series is also built in 24VAC/VDC at 150mA.
5) Will the CL33905 latch into the strike already in my frame?
Depends on what's cut into the frame. It ships with a 217L13 ANSI curved lip strike, 4-7/8 x 1-1/4 inch with a 1-1/4 inch lip to center, so if your frames carry the standard ANSI 4-7/8 inch strike prep it drops in. The latch is a 686F17 deadlatch with a square corner front measuring 2-1/4 x 1-1/8 inch on a 2-3/4 inch backset, and the standard latchbolt throw is 1/2 inch stainless with a deadlocking auxiliary latch. On a fire rated opening you'd want the optional 3/4 inch throw fire latch instead of the 1/2 inch standard.
6) Is the Corbin Russwin CL33905 Grade 1, and what certifications does it carry?
Grade 1 under ANSI/BHMA A156.2 Series 4000, which is the heavy duty commercial rating an institutional spec usually calls for. It's also UL-cUL listed, meets ANSI A117.1 accessibility, and carries California State Fire Marshal listing. For a facility standardizing on one lockset across corridors and secure rooms, that combination is what lets the same chassis cover both the access controlled doors and the mechanical ones on the same series platform.
7) Can I put the CL33905 on a 1-3/8 inch interior door?
No. The CL33905 starts at 1-3/4 inch and runs to 2 inch, so a 1-3/8 inch door, the common older interior thickness, is below its range. For that thickness you'd be looking at a lock that publishes down to 1-3/8 inch, such as the Hager 2510 or 2525 at 1-3/8 inch to 2 inch, or the Dexter C1000 Asylum at 1-3/8 inch to 2 inch. None of those are electrified, so if the door genuinely needs remote locking, the answer is usually to change the door rather than the lock.
8) What is the closest Grade 1 cylindrical lever alternative to the Corbin Russwin CL33905 if the door does not need electrified control?
The CL33905 is a Grade 1 cylindrical leverset that is hard wired at 250mA for remote locking and unlocking. If the opening does not need remote control, the Dexter C1000 Series Entry/Office lever is a Grade 1 cylindrical keyed lever covering 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 Classroom lever is the Grade 1 keyed option for the same door range where the outside lever is locked and unlocked by key only. Both are mechanical, so the opening needs no power supply, transfer hinge or access control panel; the CL33905 keeps the key override and adds solenoid control from a remote device.
9) What should I use on the secure side of a door where the Corbin Russwin CL33905 controls the main opening but the second leaf only needs to latch?
The CL33905 is a keyed, single cylinder electrified lever. For an adjacent leaf that only needs to latch and pull with no locking, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, for doors 1-3/8 inch to 2-1/4 inch, and the Falcon T101 is a Grade 1 heavy duty passage lever in the same family. The Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors. All three are non-keyed passage function, so they keep the Grade 1 duty level of the CL33905 opening without adding a cylinder or wiring.
10) Is a keypad lever lock an equivalent substitute for the Corbin Russwin CL33905 electrified leverset?
No, they solve different problems. The CL33905 is hard wired at 12VAC/DC and is unlocked by a remote device such as a card reader or a release button, with key override through a conventional cylinder. A Delaney LP250 electronic keypad leverlock is Grade 2 and credentialed at the door itself, and the Lockey 2835 is a mechanical pushbutton keyless lever for doors 1 3/16 inch to 2 inch with no wiring at all. Choose a keypad when the code is entered at the door and no cabling is being run; choose the CL33905 when the release has to come from a remote access control point.
11) Do I have to specify handing when ordering a Corbin Russwin CL33905 lever?
Handing isn't part of the order for this one. The CL33905 is non-handed, so the same lock works on a left or right hand door and you don't need to survey each opening before ordering. The only exception in the CL3300 trim range is the FZD trim, which is handed. That makes it straightforward to stock a few spares for a building where the openings swing different ways.
12) How does the CL33905 hold up to abuse if someone yanks on a locked lever?
The outside lever spins free when the lock is secured rather than fighting the force. That Lever Release design is what keeps a forced lever from breaking the chassis on a stairwell or corridor door that gets hit hard. Independent return springs stop the lever sagging over time, the chassis is steel with a zinc dichromate coating for corrosion resistance, and anti-rotational through-bolts at 6 and 12 o'clock keep the trim from working loose. The 626 satin chrome finish is the standard commercial choice for this kind of traffic.
13) I need a Grade 1 lever on a door with no power. What can I use alongside the CL33905?
For openings on the same corridor that don't need access control, a mechanical Grade 1 cylindrical lever keeps the feel and duty level consistent without a wire run. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock covering 1-3/8 inch to 2-1/4 inch doors with a fire rating, and the Dexter C1000 Series covers keyed functions in Grade 1, including classroom, classroom security and entry/office. The BEST 9K Series 1DT single dummy trim is the Grade 1 answer for the inactive leaf of a pair.
14) Does the request to exit option on the CL33905 change what I order?
It's tied to the cylinder prep choice. The 6-pin LFIC less core version is the one that carries request to exit, giving the access control panel a signal when the inside lever is turned so the door isn't read as forced. The SFIC less core version is the plain prep without it. Pick the LFIC/RX build if the opening is monitored and you need the REX contact at the lock instead of a separate device above the door.
15) What Grade 1 lever holds the outside lever locked at all times with key access, as an alternative to the electrified CL33905?
The CL33905 in fail secure mode locks the outside lever when power is off, with the latchbolt retractable by key. Where the requirement is simply a permanently locked outside lever, the Dexter C1000 Classroom Security lever is a Grade 1 clutching keyed cylindrical lock for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 Asylum (F87) is a Grade 1 cylindrical lock for 1-3/8 inch to 2 inch doors where both levers are controlled by key. The Hager 2580 with Withnell lever is a Grade 2 storeroom cylindrical lock for 1-3/8 inch to 2 inch doors. The distinction is that the CL33905 can also be released electrically from a remote point.
16) Which lever trim matches a Corbin Russwin CL33905 opening on a door leaf that is fixed or inactive?
The CL33905 carries a lever handle on a cylindrical chassis. For an inactive leaf that needs only a matching pull, the BEST 9K Series 1DT single dummy trim is a Grade 1 non-keyed heavy duty cylindrical lever, which holds the same Grade 1 duty level as the CL33905. The Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever in the 5400 Series, and the BEST 7KC Series 1DT is the Grade 2 medium duty dummy trim. Dummy trim has no latch, so the leaf needs flush bolts or another means of holding it closed.
17) Will a lever that fits a 1-3/8 inch door work where a Corbin Russwin CL33905 is being used?
The CL33905 covers doors 1-3/4 inch to 2 inch. Several cylindrical lever peers start thinner and stop sooner: the Cal-Royal AG05 storeroom lever and the Arrow HK11 entrance lock are rated 1-3/8 inch to 1-3/4 inch, and the Kwikset 200BRNL Breton passage lever is 1-3/8 inch to 1-3/4 inch. Peers that overlap the full CL33905 range include the Arrow GL01 at 1-3/4 inch to 2 inch and the Hager 2510 at 1-3/8 inch to 2 inch. Confirm the leaf thickness before substituting, because a lock that tops out at 1-3/4 inch will not make up on a 2 inch door.
18) The CL33905 comes less core - what if my building is keyed to Schlage C rather than the Corbin Russwin keyway?
The CL33905 ships less core with prep for a 6-pin LFIC or an SFIC core, so the core is supplied to whatever keying system the building runs. Where a whole opening is being changed to a Schlage C system instead, the Cal-Royal AG03 classroom lever is furnished with a 6-pin Schlage C keyway at a 2-3/4 inch backset, matching the CL33905 backset, and the Cal-Royal AG00 entrance lever uses the same 6-pin Schlage C keyway at a 2-3/8 inch backset, which is a different bore centre. The Arrow MK33 asylum lock is also a Schlage C keyway conventional cylinder.
19) What lever designs and finishes can I get on the Corbin Russwin CL33900 electrified lockset?
The CL33905 as configured is the NZD Newport lever in 626 satin chrome, in either LFIC or SFIC less core prep. Across the CL3300 platform there are four solid cast lever designs, Armstrong, Newport, Princeton and Frascati, so if the rest of the building is already on one of the other three you can match the look while keeping the same chassis and prep. A MicroShield antimicrobial coating is offered as option code C, which is worth knowing on healthcare and pharmacy doors.
20) Which levers pair with a Corbin Russwin CL33905 on restroom and office doors in the same corridor?
A corridor standardised on the CL33905 for its controlled openings still needs privacy and passage function elsewhere. The Arrow MK02-TA is a fire rated privacy lock for 1-3/8 inch to 1-3/4 inch doors with a Tudor knob, the Hager 2540 privacy lock covers 1-3/8 inch to 2 inch, and the Accentra 5301LN Augusta is a Grade 2 passage lever in the 5300 Series. Note the CL33905 needs 1-3/4 inch to 2 inch doors, so verify each opening's leaf thickness rather than assuming the corridor is uniform.
