Corbin Russwin CL3581 NZD 626 – Frequently Asked Questions

1) What does the Corbin Russwin CL3581 actually do when the key is used, and why is there no lever on the outside?
The CL3581 is an ANSI F113 function: the deadlocking latchbolt retracts by lever, except when the lever is locked by key. One side carries the lever, the other side gets a blank plate instead of a second lever. That makes it a one-way opening, typically an office or apartment door where you only need to operate and key from the inside face, with no operating trim on the blank side.
2) Will the CL3581 cylindrical lever lock fit a 1-3/8 inch door?
Yes. The CL3581 covers doors from 1-3/8 to 1-3/4 inches, so it handles both the older 1-3/8 interior thickness and the 1-3/4 standard commercial leaf. Backset is 2-3/4 inches.
3) Do I have to order the CL3581 handed left or right?
No handing to specify. The CL3581 is non-handed, so a single lock covers left and right hand openings. That is the practical advantage for a property manager stocking spares, one part number works on any door in the building.
4) What cylinder comes in the CL3581, and can I get it prepped for my existing Corbin Russwin small format cores?
Standard is a conventional 6-pin cylinder in the L4 keyway. If you are keying into an existing Corbin Russwin large format interchangeable core system, order CL6 (less core, LFIC 6-pin) or CL7 (less core, LFIC 7-pin) and drop in your own cores. LC ships less conventional cylinder if you are supplying your own.
5) Can I order several CL3581 locks keyed alike so one key opens them all?
Yes. Keying is selectable as KD keyed different (standard) or KA keyed alike when you want one key across multiple locks. There is also a free-text field for special cylinder or keying requirements if you are matching an existing master key system.
6) My door is 2 inches thick. Will the CL3581 work?
Not as listed. The CL3581 covers 1-3/8 to 1-3/4 inch doors. For a 2 inch leaf in a cylindrical lever, the Falcon K101 is rated 1-3/8 to 2-1/4 inches and the Hager 2525 goes to 2 inches, though both are passage and entry functions rather than the F113 lever-and-blank-plate arrangement.
7) The door does not need to lock at all - what replaces the CL3581 for a corridor or closet opening?
The CL3581 is a keyed lockset with a single cylinder, so it is more hardware than a latch-only opening needs. For non-keyed passage duty at the same Grade 1 level, the Falcon K101 is a heavy-duty Grade 1 passage cylindrical lock with non-handed levers and a fire rating, covering 1-3/8 inch to 2-1/4 inch doors, and the Falcon T101 is a Grade 1 heavy-duty passage lever with pressure release. The Dexter C1000 Series Grade 1 passage lever is another non-keyed clutching option for 1-3/8 inch to 1-3/4 inch doors.
8) What is a Grade 1 alternative to the Corbin Russwin CL3581 when the opening needs a lever on both sides instead of a blank plate?
The CL3581 puts a lever on one side and a blank plate on the other, with a deadlocking latchbolt retracted by the lever except when the lever is locked by key. If both faces of the door need an operating lever, look at Dexter's C1000 Series Grade 1 classroom cylindrical lever lock, which is keyed and uses clutching levers on 1-3/8 inch to 1-3/4 inch doors, or the Dexter C1000 Series Grade 1 classroom security version for keyed control from either side.
9) Is there a lighter-duty keyed lever equivalent to the CL3581 for lower-traffic interior offices?
The CL3581 is a heavy-duty cylindrical leverset. Where traffic is lighter, the Falcon B511CP6D is a Grade 2 medium-duty cylindrical lever with entry/office function, the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever on 1-3/8 inch to 2 inch doors, and the Cal-Royal AG00 entrance lever is a Grade 2 unit with a 6-pin Schlage C keyway and 2-3/8 inch backset. Note the CL3581 ships with a conventional 6-pin L4 keyway cylinder, so a Schlage C keyway peer will not run on the same key system.
10) What should I use instead of the CL3581 on a storeroom door where the outside lever must stay locked at all times?
The CL3581 keeps the outside face as a blank plate and locks the lever by key, so it is an entrance/office style control rather than a storeroom function. For a storeroom lever where the outside lever is always locked and key retracts the latch, the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors.
11) Will a Cal-Royal or Falcon lever key into the same system as the CL3581?
Not without changing the cylinder. The CL3581 ships with a conventional 6-pin L4 keyway cylinder and also offers CL6 and CL7 less-core large format interchangeable core options for Corbin Russwin cores. Peers such as the Cal-Royal AG03 classroom lever and Cal-Royal AG00 entrance lever use a 6-pin Schlage C keyway, which is a different key section. If a facility is standardizing on one key system, keep the cylinder family consistent rather than mixing keyways across openings.
12) Is this Corbin Russwin lever lock fire rated for a labeled door?
The CL3581 is fire rated, and the latch is a deadlatch, which is what a labeled opening requires. Grade is ANSI/BHMA Grade 1 and door prep follows the standard cylindrical bored pattern with a 2-3/4 inch backset.
13) Is the CL3581 tough enough for an apartment or school corridor door?
It is built for that traffic. Heavy duty, Grade 1 cylindrical chassis with a steel, zinc dichromated substrate for corrosion resistance, and a deadlocking stainless latch. Typical use is offices, apartments and multi-family, care facilities, hotels, restaurants, retail, and schools.
14) What are my options if I want a keyed lever with levers on both sides rather than a blank plate?
The CL3581 puts a lever on one side only, with a blank plate opposite, so it will not give you outside trim. Comparable keyed cylindrical leversets that operate from both faces include the Hager 2525 Grade 2 entry lever for 1-3/8 to 2 inch doors, the Hager 2580 Grade 2 storeroom lever, the Falcon B511CP6D Grade 2 entry/office lever, and the Cal-Royal AG05 Grade 2 storeroom lever for 1-3/8 to 1-3/4 inch doors.
15) Can I standardize keying across other Corbin Russwin cylindrical locks if I install CL3581s?
Yes, that is the point of the CL3500 Series. Trim and keying carry across the Corbin Russwin cylindrical lockset family, and the CL3500 sits alongside the CL3300 extra heavy-duty and CL3800 standard-duty lines, so you can mix duty levels across a building and still run one key system and one lever design.
16) Can a dummy trim lever be used in place of the CL3581 on the blank-plate side?
No. The CL3581 is a single cylindrical lock chassis that carries the lever on one side and the blank plate on the other, with a deadlocking latchbolt. Dummy trim such as the BEST 9K Series 1DT single dummy Grade 1 trim, the BEST 7KC Series single dummy Grade 2 trim, or the Accentra 455LN Augusta Grade 1 single dummy has no latch and no chassis, so it mounts as a pull on an inactive leaf and cannot replace a latching lock.
17) We want to stop issuing keys - is there a keyless lever that covers the same opening as the CL3581?
The CL3581 is keyed with a conventional 6-pin L4 keyway cylinder. To move the same opening to code entry, the Lockey 2835 mechanical pushbutton keyless lever lock is ADA compliant and fits doors 1-3/16 inch to 2 inch, the Lockey 2835DC adds a second combination, and the Lockey 1150 heavy-duty mechanical keypad lever set covers 1-1/8 inch to 2 inch doors with an adjustable backset on the 1150S. The Delaney LP250 is a Grade 2 electronic keypad leverlock. Keyless units run on codes, so they will not join an existing L4 key system.
18) The door is 2 inches thick - which lever locks cover that when the CL3581 backset and thickness do not fit?
The CL3581 is catalogued for 1-3/8 inch to 1-3/4 inch doors with a 2-3/4 inch backset. For thicker leaves, the Hager 2510 Grade 2 passage and Hager 2525 Grade 2 entry levers both cover 1-3/8 inch to 2 inch, the Arrow GL01 Grade 2 passage lever covers 1-3/4 inch to 2 inch, and the Falcon K101 Grade 1 passage lever reaches 1-3/8 inch to 2-1/4 inch.
19) How does the CL3581 differ from a residential-grade keyed lever like the Kwikset or Master Lock units?
The CL3581 is a heavy-duty commercial cylindrical leverset built to ANSI function F113 with a Grade 1 rating, a stainless deadlatch and a conventional 6-pin L4 cylinder. The Master Lock BC Series RL01 keyed entry lever is Grade 3, and the Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 for 1-3/8 inch to 1-3/4 inch doors and are not keyed entry functions at all. Grade 3 levers are built for lighter cycle counts than a Grade 1 commercial chassis.
20) For a restroom or patient room, is the CL3581 the right function or should I use a privacy or asylum lock?
The CL3581 locks its lever by key and presents a blank plate on the opposite face, so there is no inside thumbturn for occupant privacy. For bed and bath openings the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob and a fire rating, and the Hager 2540 uses the Withnell lever on 1-3/8 inch to 2 inch doors. Where both faces need key control, the Dexter C1000 Series asylum lock (F87) is Grade 1 for 1-3/8 inch to 2 inch doors and the Arrow MK33-BD-CS is a heavy-duty asylum cylindrical lock with a Schlage C keyway conventional cylinder.
21) Can decorative residential leversets substitute for the CL3581 in a commercial corridor?
They serve a different opening. The CL3581 is a commercial cylindrical leverset, non-handed, with a Grade 1 rating and a fire rating. Decorative lines such as the Baldwin Estate 5103 passage and privacy levers with the 5048 rose, the Deltana 6201 Manchester and 6431 Linstead entry levers for 1-3/8 inch to 2 inch doors, and the Emtek Classic and Arts & Crafts dummy pairs are trim-led designs, with the Baldwin 5103 half dummies supplied handed left or right. Where a rated commercial opening is involved, stay with the cylindrical commercial chassis.
22) Which lever designs and finishes does the CL3581 come in for matching existing doors?
Three lever designs: AZD Armstrong, NZD Newport, and PZD Princeton. Fourteen finishes are offered, from 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 and 613L oil-rubbed bronze, 613E dark oxidized equivalent, 722 black oxidized bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, through to BSP black suede and WSP white suede powder coat. NZD Newport in 626 satin chrome is the common commercial pairing.
23) If I want a Grade 1 non-keyed lever from the same tier as the CL3581 for the back of a suite, what matches?
The CL3581 is a Grade 1 heavy-duty cylindrical leverset. At the same Grade 1 tier without a cylinder, the Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors, while the Design Hardware J75 covers the same 1-3/4 inch door at Grade 2. The Accentra 5301LN Augusta and 4601LN are Grade 2 passage levers if the tier can drop.
