Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness (1-3/8" to 1-3/4"), backset (2-3/4"), and bore hole dimensions as specified for the CK4400 Series.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on the door face and edge for the latch bore and cross-bore.
  3. Prepare the door by drilling the required cross-bore and latch bore holes, and routing the latch face plate mortise on the door edge per manufacturer instructions.
  4. Install the 574F55 latch assembly (2-3/4" backset, square corner front, 2-1/4" x 1-1/8") into the door edge and secure with provided wood or machine screws.
  5. Mount the exterior and interior knob assemblies through the cross-bore, aligning the spindle and connecting components per manufacturer instructions. Secure with provided fasteners.
  6. Install the ANSI curved lip strike (4-7/8" x 1-1/4" x 1-1/4" lip to center) on the door frame, mortising as required for flush fit.
  7. Test latchbolt operation from both sides to confirm both knobs retract the latch freely. Make final adjustments as needed. Refer to manufacturer documentation for complete installation details and troubleshooting.

Corbin Russwin CK4410 GWC 612 – Frequently Asked Questions

1) Will the Corbin Russwin CK4410 passage knobset fit a 1-3/8 inch interior door?
Yes. The CK4410 knobset covers 1-3/8 inch through 1-3/4 inch doors, so it works on older 1-3/8 inch interior and closet doors as well as standard 1-3/4 inch commercial leaves. Door prep is a 2-3/4 inch backset, which is the deeper of the two common bored-lock backsets, so a door already bored at 2-3/8 inch will not take it without re-boring.
2) Does the CK4410 knob lock or key at all, or do both knobs always turn?
Both knobs always turn. The CK4410 is a passage function lock, non-keyed, with the latchbolt retracting by knob from either side and no locking of any kind. Use it on hall, closet and corridor doors. If you need the door to lock from inside for a bathroom or bedroom, a passage function is the wrong choice and you want a privacy set instead, like the Dexter C2000 privacy ball knob.
3) Do I have to order the CK4410 handed for a left or right hand door?
No handing to specify. The CK4410 is non-handed, so one part number covers both left- and right-hand openings, and the stainless steel latchbolt adjusts for flat or beveled door edges. That is why property managers can stock one item for a whole building instead of splitting inventory by hand.
4) Will the CK4410 latch drop into my existing strike, or do I need to re-mortise the frame?
It ships with an ANSI curved lip strike, 4-7/8 x 1-1/4 inches with 1-1/4 inch lip to center. If the frame is already prepped for a full-size ANSI strike, that is a direct swap. Frames cut for a small round-corner residential strike will need the opening enlarged to the 4-7/8 inch ANSI box. Latch face is 2-1/4 x 1-1/8 inches on a square corner front.
5) What is the closest equivalent to the Corbin Russwin CK4410 passage knob from another manufacturer?
The Dexter C2000 passage cylindrical ball knob lock is the nearest match. Both are Grade 2 non-keyed passage/hall/closet knobsets fitting doors 1-3/8 inch to 1-3/4 inch thick, so the door prep and the function are the same. The difference is the knob style and the series: the Dexter uses a ball knob in the C2000 Series, while the CK4410 comes from the Corbin Russwin CK4400 Series with a global knob. The Arrow MK01 and Arrow RK01 are also Grade 2 non-keyed passage knobsets covering the same 1-3/8 inch to 1-3/4 inch door range, with the RK01 in a ball knob style.
6) I need a passage knob on a labeled fire door - what should I use instead of the CK4410?
Look at the Falcon W101 or the Falcon X101. Both are cylindrical passage/hall/closet knob locks carrying a fire rating: the W101 is a Grade 2 medium duty knob lock with a 2-3/4 inch backset in the W Series, and the X101 is a Grade 1 heavy duty passage knobset with an interchangeable core in the X Series, fitting doors 1-3/8 inch to 2-1/4 inch thick. The CK4410 is a Grade 2 passage knobset with a 2-3/4 inch backset, so the W101 matches its backset and grade directly.
7) Is a dummy knob the same thing as a passage knob like the CK4410?
No. The CK4410 has a working latchbolt that retracts by knob from either side with both knobs always free, so it holds the door closed. A dummy knob has no latch and no moving mechanism - it is surface mounted trim for pull-only doors. The BEST 6K single dummy trim is a Grade 2 medium duty non-keyed cylindrical knob lock in the 6K Series, the Schlage A170 is a Grade 2 heavy duty single dummy trim in the A Series for doors 1-3/8 inch to 1-7/8 inch, and the Cal-Royal BA40 is a dummy knob for doors 1-3/8 inch to 1-3/4 inch. Order one of those only if the door does not need to latch.
8) The bathroom door needs a lock on the inside - what do I order instead of the CK4410?
The CK4410 is a passage function knob with both knobs always free, so it never locks. For a bathroom or bedroom, order a privacy function knob instead. The Dexter C2000 privacy cylindrical ball knob lock is Grade 2, non-keyed, and fits the same 1-3/8 inch to 1-3/4 inch door thickness range as the CK4410. The Cal-Royal BER20 and the Pamex FTF privacy Baron knob lockset are Grade 3 privacy knobs covering the same door thickness range.
9) The door is thicker than 1-3/4 inch - which passage knob covers it?
The CK4410 is rated for doors 1-3/8 inch to 1-3/4 inch. For a thicker door, the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core rated 1-3/8 inch to 2-1/4 inch. Among non-passage knobs on thicker doors, the Deltana 6171 round knob entry and Deltana 3381 egg knob entry cover 1-3/8 inch to 2 inch, but those are entry function rather than passage.
10) Is a Grade 2 passage knobset enough for an office corridor, or should I spend up to Grade 1?
Grade 2 to ANSI/BHMA F75 covers apartments, motel interiors, offices and light commercial traffic, which is what the CK4400 Series is built for. On a high-traffic opening or where a facility standardizes on heavy duty, step up to a Grade 1 passage knob such as the Schlage D10S or the Falcon X101, which also carries a wider 1-3/8 to 2-1/4 inch door range.
11) I need a knob on a closet door that doesn't latch at all. Is the CK4410 what I want?
No. The CK4410 has a working latchbolt, so the door latches every time it closes. For a knob that is trim only, on a false door, a bi-fold, or the inactive leaf of a pair, order a dummy set instead: the Schlage A170 single dummy or the BEST 6K single dummy trim are both Grade 2 non-keyed dummies.
12) Does the Corbin Russwin CK4410 come with mounting screws, or do I need to supply fasteners?
Screws are in the box. The CK4410 ships with both wood and machine screws, so it mounts to wood doors and to metal doors with tapped frames prep without a separate fastener order. Also included are the 574F55 latch and the ANSI curved lip strike, so the only thing a crew needs on site is the door prep itself: cross-bore, latch bore, and the edge mortise for the 2-1/4 x 1-1/8 inch latch face.
13) Is the CK4400 Series knob a cylindrical bored lock or a mortise lock?
Cylindrical. The CK4410 is a bored cylindrical knobset, so it installs into a round cross-bore through the door face plus a latch bore in the edge, not a rectangular mortise pocket. If the existing doors are prepped for mortise locks, this is not a drop-in and the pocket would have to be filled or the door replaced.
14) The office door needs to lock with a key - what is the keyed version to pair with a CK4410 passage knob?
The CK4410 is non-keyed. For keyed openings on the same run of doors, the Dexter C2000 entry/office cylindrical ball knob lock is a Grade 2 keyed knob covering the same 1-3/8 inch to 1-3/4 inch door thickness range, and the Dexter C2000 classroom knob is the Grade 2 keyed classroom function in the same series. The Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder from the 6 Line Series, and the Sargent 8XG04 is the Grade 1 heavy duty storeroom/closet knob with a 2-3/4 inch backset, matching the CK4410 backset.
15) What is a lighter duty passage knob than the Corbin Russwin CK4410?
The Pamex FTF Baron knob lockset in passage function is a Grade 3 passage/hall/closet knob for doors 1-3/8 inch to 1-3/4 inch, the same door range the CK4410 covers at Grade 2. The Kwikset 200P Polo passage knob is an interior hall and closet knob that ships with a 6AL latch and RCS round corner strike; the 200P-CP version comes with a round corner adjustable latch and round corner strike. Note the strike difference against the CK4410, which ships with an ANSI curved lip strike measuring 4-7/8 inch by 1-1/4 inch with a 1-1/4 inch lip to center - a round corner strike will not drop into an ANSI strike mortise without reworking the frame.
16) I need a decorative passage knob for a residential unit instead of a commercial cylindrical knobset - what are the options?
The CK4410 is a commercial cylindrical knobset with a 2-3/4 inch backset. For a decorative interior look, the Baldwin Estate 5011 Colonial passage knob uses a 5058 rose, and the Baldwin Estate 5000 Baltimore passage lock is preconfigured with a 5048 rose, a 2-3/8 inch backset, and a full lip strike - a different backset from the CK4410, so confirm the existing door bore before swapping. The Omnia 434/PA egg-shaped knob latchset is a solid brass passage/hall/closet set with a 3 inch projection. The Bravura Albany, Lynchburg, and Dallas knobsets are Grade 2 passage knobsets with round or rectangular trim, matching the CK4410 grade.
17) I need a keyless door that still pushes open freely - is the Lockey 3830 a substitute for the CK4410?
Not a like-for-like swap. The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, covering doors 1 3/16 inch to 2 inch thick. It self-locks and requires a combination from the outside. The CK4410 has both knobs always free at all times with no locking at all, and fits doors 1-3/8 inch to 1-3/4 inch. Use the 3830 only where the door is meant to secure behind the user, not on a hall or closet door that must stay free from both sides.
18) Can I standardize a whole floor on one knob series with the CK4410?
The CK4410 is the passage/hall/closet function in the Corbin Russwin CK4400 Series, non-handed and Grade 2, so it fits both left and right hand doors without modification. If a single-series program across passage, privacy, entry, and classroom openings is the goal, the Dexter C2000 Series carries all four as Grade 2 knobs: passage, privacy, entry/office, and classroom, each for doors 1-3/8 inch to 1-3/4 inch. The Pamex FTF Baron series covers passage, privacy, and entrance/office at Grade 3 over the same door range.
19) What finishes does the Corbin Russwin CK4410 come in?
Two: 612 satin bronze and 629 bright stainless steel. If the rest of the building is on 626 satin chrome or a US10B oil-rubbed look, 612 is the warmer match and 629 the brightest of the two.
