Corbin Russwin CL3820 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CL3820 privacy lever fit a 1-3/8 inch interior door?
Yes. The CL3820 privacy leverset is built for doors 1-3/8 to 1-3/4 inches thick, which covers both the older 1-3/8 inch interior doors common in existing buildings and the 1-3/4 inch standard commercial door. Backset is 2-3/4 inches, the deeper of the two usual bored-lock backsets, so check the cross-bore location on an existing prep before you order.
2) How does the CL3820 restroom lock get opened from outside in an emergency?
Three ways. An emergency release tool from the outside will unlock it, rotating the inside lever throws the button off, and simply closing the door releases it as well. The inside lever is always free, so someone in the room can always get out without touching the button. That is ANSI function F76A, the standard privacy/bed/bath function.
3) Is a Grade 2 privacy lock enough for a commercial restroom, or should I go Grade 1?
Grade 2 medium duty covers standard commercial traffic: offices, multi-family units, retail, hospitality, closets and school interior doors. The CL3820 uses solid cast levers with no plastic inserts, thrubolts to stop chassis rotation, and freewheeling Lever Release levers so a kick or a hard pull on a locked lever spins rather than breaks the chassis. For a high abuse opening, Corbin Russwin's CL3300 and CL3500 Series are the Grade 1 step up, and the CL3800 is meant to be mixed with them so you spend the Grade 1 money only where the traffic warrants it.
4) Will the CL3820 fit a narrow aluminum stile door?
Only if the stile is at least 4-1/2 inches. Below that the chassis will not fit and you are looking at a narrow stile device, not a bored cylindrical lock. On a standard 1-3/4 inch wood or hollow metal door the 4-1/2 inch minimum is a non-issue.
5) I need a lever that just latches, no lock button. Is the CL3820 the right one?
No. The CL3820 is a privacy function with a push button, meant for restrooms and bedrooms. For a door that only needs to latch, a passage lever is the part: the Falcon B101 is a Grade 2 medium duty non-handed passage lever, and the Accentra 4601LN with Augusta trim is another Grade 2 passage option. If the opening is fire rated and heavier traffic, the Falcon K101 is a Grade 1 passage lever with a fire rating and a 1-3/8 to 2-1/4 inch thickness range.
6) Can a Kwikset 300BRNL Breton privacy lever be substituted for a Corbin Russwin CL3820 on a commercial job?
They serve the same function on paper - the Kwikset 300BRNL Breton is a privacy lever set for doors 1-3/8 inch to 1-3/4 inch, the same door range the CL3820 covers - but they are graded for different service. The Breton is Grade 3, while the CL3820 is ANSI/BHMA Grade 2 and specified for commercial use with a UL 3-hour fire rating. A restroom or office door written to a commercial spec or sitting in a fire-rated opening needs the CL3820; the Grade 3 lever suits lighter residential-style duty.
7) What is the closest cross-brand equivalent to the Corbin Russwin CL3820 privacy lever lock?
The Hager 2540 with the Withnell lever is the nearest match on the core points that matter for a bath or bedroom door: it is a Grade 2 cylindrical privacy lock like the CL3820, and it fits doors 1-3/8 inch to 2 inch, which covers the CL3820 door thickness range of 1-3/8 inch to 1-3/4 inch. The CL3820 is non-handed and carries ANSI function F76A with push-button locking and outside emergency release. Lever style is the practical difference: the CL3820 comes in Armstrong, Newport and Princeton lever designs, while the Hager 2540 uses the Withnell lever.
8) Is there a knob version of a Grade 2 commercial privacy lock instead of a lever?
The Arrow MK02-TA is a privacy function cylindrical lock with a Tudor knob rather than a lever, and it is fire rated. Two things to check before swapping: it fits doors 1-3/4 inch to 2 inch, where the CL3820 covers 1-3/8 inch to 1-3/4 inch, so a thin 1-3/8 inch door needs the CL3820; and a knob is not ADA-compliant operable hardware, so any door on an accessible route wants the lever. The CL3820 is offered with Armstrong, Newport or Princeton levers.
9) The door does not need to lock at all - what should I order instead of a privacy lever?
A closet, corridor or storage door that only needs a latch takes a passage function lockset, which has no push button and no locking at all. The Falcon B101 is a Grade 2 medium-duty cylindrical passage lever lock with a non-handed design, matching the CL3820 on grade, medium duty level and non-handed installation while dropping the privacy locking. The Accentra 5301LN Augusta and the Hager 2510 with Withnell lever are also Grade 2 passage cylindrical levers. The CL3820 is the one to keep wherever the room needs to be secured from inside, since its outside lever locks by push button and releases with an emergency tool.
10) The door needs a key from the outside - what replaces a privacy lever?
The CL3820 is non-keyed, so any opening that has to be secured with a key needs a keyed lockset instead. The Hager 2580 with Withnell lever is a Grade 2 storeroom cylindrical lock fitting doors 1-3/8 inch to 2 inch, and the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch. For an office door that toggles between locked and unlocked, the Hager 2525 is a Grade 2 commercial entry lever and the Falcon B511CP6D is a Grade 2 medium-duty entry/office lever. Keep the CL3820 for restrooms and bed/bath doors where push-button privacy is all that is wanted.
11) Does a Corbin Russwin CL3820 lever have to be ordered left or right hand?
No handing to specify. The CL3820 is non-handed, and a non-handed spring cassette keeps the lever from sagging over time. One part number works on either swing, which is what you want when you are buying a batch for a floor of restrooms and do not want to count doors.
12) What do I have to specify when ordering a Corbin Russwin CL3820?
Lever style and finish are the two choices that build the part number. Levers are Armstrong (AZD), Newport (NZD) and Princeton (PZD). Finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed satin bronze, 613E and 613L dark oxidized bronze, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze oil-rubbed, BSP black suede and WSP white suede powder coat. Latch front corner and strike lip length are optional swaps if the existing prep calls for them.
13) Can I key a Corbin Russwin CL3820 into my building master key system?
No, the CL3820 is a non-keyed privacy lock with no cylinder in it. If the door needs to be on the master, you want a keyed function from the CL3800 Series instead, such as an entrance/office or storeroom lock. Keep the CL3820 for restrooms, bed/bath and closets where privacy is all the door needs.
14) What should I use on a high-traffic door where a Grade 2 privacy lever is not enough?
Step up to Grade 1 for doors taking institutional or heavy public traffic. The Falcon K101 is a Grade 1 heavy-duty non-handed passage cylindrical lock, fire rated, fitting doors 1-3/8 inch to 2-1/4 inch, and the Falcon T101 is a Grade 1 heavy-duty passage lever with pressure release. Both are passage function, so they latch without locking. Where the room must lock from inside and Grade 2 medium duty suits the traffic, the CL3820 covers it with F76A privacy and a UL 3-hour fire rating.
15) Is a Baldwin Estate 5103 privacy lever the same thing as a CL3820?
Both carry privacy function, but they are built for different jobs. The Baldwin Estate 5103 privacy lever comes on a 5048 rose as a decorative residential-style set. The CL3820 is a commercial cylindrical lockset, ANSI F76A, ANSI/BHMA Grade 2, non-handed, with a stainless steel latchbolt and an ANSI curved lip strike, and it is UL listed for 3-hour fire doors. For a hotel guest bath, an apartment interior or a residential remodel where the look drives the choice, the Baldwin is the design-led option; for a code-driven commercial opening, the CL3820 is the one that carries the certifications.
16) I need a matching lever on an inactive or closet door - what pairs with a CL3820?
An inactive leaf, a closet face or a pull-only door takes a dummy trim, which mounts a fixed lever with no latch and no chassis. The BEST 7KC Series 1DT is a Grade 2 medium-duty single dummy trim cylindrical lever, matching the CL3820 on grade and duty level, and the BEST 9K Series 1DT is the Grade 1 heavy-duty equivalent. The Callan Bentley is another Grade 2 dummy lever. Dummy trim does not latch or lock, so it never substitutes for the CL3820 on a door that must close and secure.
17) What lock goes on a patient room or behavioral health door instead of a standard privacy lever?
Rooms where staff must never be locked out take an asylum or institutional function rather than privacy. The Dexter C1000 Series asylum lock is a Grade 1 ANSI F87 cylindrical lock for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy-duty asylum cylindrical lock with a ball knob and a Schlage C keyway conventional cylinder. The CL3820 is ANSI F76A privacy, non-keyed, with the outside lever released by an emergency tool, by rotating the inside lever or by closing the door - the right function for restrooms and bed/bath doors, not for supervised rooms that need key control on both sides.
18) Would a keyless pushbutton lever like the Lockey 2835 work in place of a privacy lock?
No - the Lockey 2835 mechanical pushbutton keyless lever is a passage function lock, meaning the code releases the latch for entry rather than securing the room from inside. It suits doors 1 3/16 inch to 2 inch and is ADA compliant. The CL3820 does the opposite job: the outside lever is locked by push button from inside and freewheels while locked, with release by emergency tool, by turning the inside lever, or by closing the door. For a restroom or bed/bath door, the CL3820 privacy function is the correct choice; the keyless lever belongs on a door where controlled entry, not occupant privacy, is the requirement.
19) Do I have to worry about handing when cross-referencing a privacy lever against another brand?
Not with the CL3820 - it is non-handed, so one part number covers left and right hand doors. Several Grade 2 peers are built the same way, including the Falcon B101 passage lever with a non-handed design and the Falcon K101. Where handing does enter the order is on decorative sets sold as hand-specific pieces: the Baldwin Estate 5103 half dummy is ordered as a left hand or a right hand part. When substituting, confirm whether the peer part number carries a hand in it before quoting a mixed-hand building.
20) How does the CL3820 hold up in a damp restroom or a coastal building?
The chassis is steel with a zinc dichromate treatment for corrosion resistance, and the levers are solid cast with no plastic inserts. Antimicrobial MicroShield finish options are offered alongside the 14 standard finishes, which is worth specifying in healthcare and food service washrooms.
21) What is the difference between the CL3820 and a Grade 3 leverset for an apartment interior door?
Grade 3 leversets such as the Cal-Royal AUS00 entrance/office lever with a solid brass forged body, for doors 1-3/8 inch to 1-3/4 inch, and the Callan Asheville passage lever cover the same door thicknesses but are certified to a lighter ANSI/BHMA grade. The CL3820 is Grade 2, specified commercial, non-handed, and fire rated. Property managers standardizing across a building typically match grade to traffic: unit interiors can take Grade 3, while corridor-facing and fire-rated openings and anything in a common area are where the Grade 2 CL3820 belongs.
