Cal-Royal CGN04-26D – Frequently Asked Questions

1) What is a communicating lock, and when would I use the Cal-Royal CGN04 instead of a regular entry lever?
A communicating lock is for an opening shared between two rooms, like connecting hotel rooms or adjoining offices, where either side needs to control access independently. On the CGN04, the deadlocking latchbolt is retracted by the lever from either side, and each lever is locked or unlocked separately by turning a key on its own side. That is the ANSI F80 function. If only one side needs key control and the other side is always free egress, you want an entrance or office function instead, such as the Dexter C1000 Entry/Office lever.
2) Will the Cal-Royal CGN04 fit a 1-3/8 inch door, or does it need a standard 1-3/4 inch commercial door?
Both work. The CGN04 covers a 1-3/8 to 1-3/4 inch door thickness range as standard, which spans the common older interior door and the standard commercial door. For thicker slabs, 2 to 2-1/4 inch is available on request. The bore is 2-1/8 inches diameter, the usual cylindrical prep.
3) Will the CGN04 latch into the strike already in my frame?
It ships with a 4-7/8 x 1-1/4 inch ASA/ANSI strike with a curved lip, cut to ANSI A115.2 frame prep. If your frame is already prepped to A115.2 with a standard ASA cutout, the new strike drops straight in. The latchbolt has a 1/2 inch throw and deadlocks, so the strike lip depth needs to let it seat fully; a shallower residential T-strike or a round-corner strike is a different prep and will need the frame reworked.
4) Can the Cal-Royal CGN04 go on a fire-rated door?
Yes. The CGN04 is fire rated and UL/cUL listed up to 3 hours, so it can be used on rated openings up to a 3 hour label.
5) Can I key the Cal-Royal CGN04 into my existing Schlage C master key system?
Yes. The CGN04 comes standard with a 6-pin solid brass C keyway, and the cylinder is also available for Schlage E, Schlage C-K, Russwin D1-2-3-4, Corbin 59/60, Corbin-Russwin L4, Sargent LA-LB-LC, Falcon/Weiser E, Arrow A, Yale 8, Yale GA and Kwikset. It will also take Medeco, Assa, Kaba and Cal-Royal HSK high security cylinders if the building is on a restricted system. The outside lever is key removable, which speeds up re-keying without pulling the whole lock.
6) Does the Cal-Royal CGN04 take a BEST small format interchangeable core?
It does. The CGN04 accepts compatible 6 or 7 pin interchangeable cores from BEST, Falcon and Arrow, so a facility already standardized on SFIC can core it to the house system. Large format cylinder options are available for Schlage, Corbin/Russwin, Sargent and Yale. Note that both levers on a communicating lock are keyed, so budget a core for each side.
7) My door is 2 inches thick. Can I still use a Grade 1 cylindrical lever there?
Not with the standard CGN04, which is built for 1-3/8 to 1-3/4 inch doors, though Cal-Royal will supply it for 2 to 2-1/4 inch on request. If you need something off the shelf at that thickness, the Falcon K101 Grade 1 passage lock covers 1-3/8 to 2-1/4 inch, and the Corbin Russwin CL3110 Grade 1 passage lock covers 1-3/4 to 2 inch. Both are passage function, so neither gives you key control.
8) What is the closest Grade 1 heavy duty cylindrical lever lock to the Cal-Royal CGN04 if I need a keyed classroom function instead of communicating?
The Cal-Royal CGN04 is a Grade 1 heavy duty cylindrical leverset with a communicating function, where each lever is independently locked or unlocked by key. If the opening calls for classroom function rather than communicating, the Dexter C1000 Series classroom lever lock is a keyed Grade 1 cylindrical lever with a clutching mechanism and a 1-3/8 inch to 1-3/4 inch door thickness range, matching the CGN04 door thickness range of 1-3/8 inch to 1-3/4 inch. Both are keyed cylindrical bored locksets, so the door prep is the same family of cutout; the difference is which side the key controls and whether both levers lock independently.
9) Is the Falcon K101 a substitute for the Cal-Royal CGN04?
No. The Falcon K101 is a Grade 1 heavy duty cylindrical lock with non-handed levers and a passage function, meaning it is non-keyed and the levers always retract the latch. The Cal-Royal CGN04 is keyed on both sides with a communicating function, where each lever locks independently by key. Both are Grade 1 heavy duty and both are fire rated, and both are non-handed, so they sit on similar openings, but the K101 gives no key control at all. It covers doors 1-3/8 inch to 2-1/4 inch where the CGN04 covers 1-3/8 inch to 1-3/4 inch.
10) Can I use a Grade 2 lever like the Hager 2580 in place of the Cal-Royal CGN04 on a fire rated opening?
The Cal-Royal CGN04 is Grade 1, fire rated, and UL/cUL listed up to 3 hours. The Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever covering doors 1-3/8 inch to 2 inch, and its function is storeroom rather than communicating, so the outside lever is always locked and retracted by key only. Where the specification calls out Grade 1 and a fire rating, the CGN04 is the one that carries both; the 2580 is a Grade 2 storeroom lever for a different opening.
11) Do I have to specify handing on the Cal-Royal CGN04 communicating lock?
No handing to specify. The CGN04 is non-handed, so one part number covers left and right hand openings and you do not have to survey which way each door swings before ordering a batch.
12) Is the Cal-Royal CGN04 heavy duty enough for a school or hospital corridor?
It is built for that traffic. The CGN04 meets or exceeds BHMA/ANSI A156.2 Series 4000 Grade 1, the top cylindrical lock grade, and is classed heavy duty commercial. Construction is cold rolled steel housing with a zinc dichromate rust-resistant finish and a precision cast steel retractor. The clutch lets the outside lever spin free when locked instead of transferring force into the mechanism, which is what usually saves a lever in an abused corridor.
13) What finishes does the Cal-Royal CGN04 come in, and will it match the other levers in my building?
Three finishes: US26D satin chrome, US26 polished chrome, and US10B antique bronze oiled. US26D is the usual commercial default and is what most institutional openings are standardized on. If your existing hardware is brass or nickel, this lock will not match, and mixing a chrome lever into a brass corridor is the most common reason a fleet order comes back.
14) Will the Cal-Royal CGN04 lever clear a narrow frame or an adjacent wall?
The CGN04 uses a full-length 4-3/4 inch lever on a 3-1/2 inch diameter rose. On a tight return wall or a door hung close to a corner, measure your clearance against that 4-3/4 inch lever length before ordering, since a lever this long needs swing room a knob would not. Each lever has its own spring cage and the trim is thru-bolted through the door.
15) I need a Grade 1 lever for a two-room connecting door but do not want key control on both sides. What else is there?
The communicating function on the CGN04 exists specifically so each side keys independently, so if that is not what the opening needs, look at a different function in Grade 1. The Dexter C1000 Series covers Grade 1 classroom, classroom security and entry/office levers, all rated 1-3/8 to 1-3/4 inch door thickness like the CGN04. For a non-keyed opening, the Falcon K101 is a Grade 1 fire rated passage lever covering 1-3/8 to 2-1/4 inch doors, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant fire rated passage lock for 1-3/4 to 2 inch doors.
16) I need an office or entry lever on the same doors as a Cal-Royal CGN04 - what Grade 1 option keeps the same duty level?
For an entry or office opening alongside CGN04 communicating locks, the Dexter C1000 Series entry/office cylindrical lever lock is Grade 1, keyed, clutching, and covers doors 1-3/8 inch to 1-3/4 inch, the same door thickness range the CGN04 carries. The CGN04 stays the right choice where each side must be keyed independently, such as connecting doors between two rooms; the entry/office lever is the one for a door with a single controlled side.
17) What lever matches the Cal-Royal CGN04 on a door that needs no lock at all, like a corridor or closet?
For an unlocked opening in the same building, 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 hold the same Grade 1 rating as the Cal-Royal CGN04 but are passage function, so the levers always retract the latch and there is no cylinder to key. The CGN04 remains the choice where each side needs independent key control.
18) The Cal-Royal CGN04 uses a Schlage C keyway - what other lock in the same class keys to Schlage C?
The Cal-Royal CGN04 comes with a Schlage C keyway as standard. In the same cylindrical bored family, the Arrow MK33-BD-CS is a heavy duty asylum function cylindrical lock with a conventional cylinder in Schlage C keyway, so it can join the same key system. It is Grade 2 with a ball knob rather than a lever, and its function is asylum, meaning both sides are key operated at all times rather than each lever locking independently as on the communicating CGN04.
19) If I want a keyless lever on a connecting door instead of the keyed Cal-Royal CGN04, what are the options?
The Cal-Royal CGN04 is a keyed single cylinder communicating lock. For a keyless approach on a similar opening, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1 3/16 inch to 2 inch, and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination and passage function for doors 1-1/8 inch to 2 inch. These trade key control for a combination and do not provide the independent per-side key locking the CGN04 gives.
20) What is the difference between the Cal-Royal CGN04 and the Dexter C1000 asylum lock for a healthcare corridor?
Both are Grade 1 cylindrical locks. The Cal-Royal CGN04 is communicating: a deadlocking latchbolt worked by lever from either side, with each lever independently locked or unlocked by key, and it fits doors 1-3/8 inch to 1-3/4 inch. The Dexter C1000 Series asylum lock is function F87 and fits doors 1-3/8 inch to 2 inch. Asylum function means the key operates from both sides with no free lever egress, while the communicating CGN04 allows lever operation from either side unless that side has been keyed locked.
21) Does a Baldwin Estate 5103 privacy lever do the same job as a Cal-Royal CGN04 on a connecting door?
No. The Baldwin Estate 5103 with 5048 rose is a privacy lever, which locks by thumbturn from inside with an emergency release outside. The Cal-Royal CGN04 is a Grade 1 heavy duty communicating lock, keyed with a single cylinder function, where each side is locked or unlocked by a key rather than a turn. On a connecting door between two occupied rooms where either party must control their own side by key, the CGN04 is the mechanism that does it; the 5103 privacy is a residential-style bath and bedroom lever.
22) Is the Corbin Russwin CL33903 electrified lever an alternative to the Cal-Royal CGN04?
They solve different problems. The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running on 12VAC/DC for doors 1-3/4 inch to 2 inch, so it is tied into an access control system and unlocks on power loss. The Cal-Royal CGN04 is a mechanical Grade 1 communicating lock with a Schlage C keyway and no wiring, for doors 1-3/8 inch to 1-3/4 inch. Choose the CL33903 when the opening is on a credential system, the CGN04 when key control at each lever is the requirement.
23) What stops someone snapping the lever off the Cal-Royal CGN04 when the door is locked?
A clutch. When the CGN04 is in the locked position the handle turns free without retracting the latch, so force on the lever does not load the retractor. That is the point of the clutch on a Grade 1 lock in a public building, and it is why a kicked or hung-on lever tends to spin rather than shear.
24) I need a dummy lever to trim the inactive leaf on a pair where the active leaf has a Cal-Royal CGN04 - what works?
The BEST 9K Series 1DT single dummy trim is a Grade 1 heavy duty non-keyed cylindrical lever, matching the Grade 1 heavy duty rating of the Cal-Royal CGN04. The Accentra 455LN Augusta from the 5400 Series is also a Grade 1 heavy duty single dummy cylindrical lever lock. Both are dummy function, so there is no latch and no cylinder; they are surface trim for the leaf that does not need to latch.
