Corbin Russwin CLX3357 NVSL 626 V30 – Frequently Asked Questions

1) Will the Corbin Russwin CLX3357 storeroom lever lock fit a 1-3/8 inch door?
Not as it ships. The CLX3357 is set up for 1-3/4 inch to 2 inch doors as standard. Corbin Russwin offers a D138 option for 1-3/8 inch doors and a D214 option for thicknesses over 2 inch up to 2-1/4 inch, so a thinner or thicker leaf has to be specified as that option rather than adjusted in the field from the standard build.
2) Do I need to order the CLX3357 lever lock handed for a left or right hand door?
No handing to specify. The CLX3357 is non-handed, so one lock covers left and right hand openings. On the double indicator versions (V33 and V66) both faces read status, and on the single indicator versions (V30, V60) the indicator sits on the outside regardless of which way the door swings.
3) Will this lock latch into the strike and latch prep already in my door?
The standard prep is a 2-3/4 inch backset with a deadlatch on a 2-1/4 x 1-1/8 inch square corner front, and an ANSI curved lip strike with a 1-1/4 inch lip length. Standard latchbolt throw is 1/2 inch, with an optional 3/4 inch deadlocking fire latch. If your existing doors are prepped at 2-3/8, 3-3/4 or 5 inch backset, those backsets are available as options. Door prep follows ANSI/SDI A250.14, and the lock needs a minimum 4-1/2 inch stile.
4) What does the storeroom function actually do when someone is inside the room?
Outside lever stays locked at all times and is retracted only by key; the inside lever is always free, so egress is one motion no matter what. The latchbolt is deadlocking, and the outside lever freewheels when locked instead of resisting force, which is what protects the chassis from someone hanging on it. There is no inside button or thumbturn to leave the outside unlocked, so a storeroom or utility room cannot be accidentally left open.
5) Can I use this lever lock on a fire rated door?
Yes. The CLX3357 is fire rated and UL/cUL listed for 3-hour fire doors, and complies with NFPA 80. It is also ANSI/BHMA A156.2 (2022) Series 4000 Grade 1, ADA A117.1 compliant, and windstorm/hurricane certified. For fire openings, order the 3/4 inch deadlocking fire latch option rather than the standard 1/2 inch throw latch.
6) Can I get a batch of these keyed alike for a building, and what keyway do they come in?
Yes. Keying is a required selection: KD keyed different is standard, or KA keyed alike when you want one key to run multiple locks. The cylinder is a conventional 6-pin brass cylinder in the L4 keyway, supplied 0-bitted as standard, and the chassis accepts all Corbin Russwin cylinder formats from fixed core through interchangeable core if you are tying into an existing master key system. Special keying instructions can be entered on the order.
7) I have narrow aluminum stile doors. Will this Corbin Russwin lever lock fit?
Only if the stile measures at least 4-1/2 inches. That is the minimum stile for the CLX3300 chassis, so a typical narrow stile aluminum storefront leaf will not take it. On those openings you need a narrow stile device rather than a bored cylindrical lock.
8) What is the closest Grade 1 indicator alternative to the Corbin Russwin CLX3357 if the opening needs a deadbolt instead of a lever lock?
The CLX3357 is a Grade 1 cylindrical storeroom lever lock with a visual status indicator. When the opening calls for a deadbolt with status visibility instead, the Schlage L460 is a Grade 1 small case mortise deadbolt, cylinder by thumbturn, with a VACANT/OCCUPIED indicator for the outside of the door, for 1-3/4 inch doors. The Schlage B660-IS-LOC is a Grade 1 heavy duty single cylinder bored deadbolt with an UNLOCKED/LOCKED indicator on the inside. Both are deadbolt-only and require a separate latch or lever set for the door to operate; the CLX3357 provides the latching lever function and the indicator in one chassis.
9) For a single-occupancy restroom, is the CLX3357 the right indicator lock or should a privacy function be used?
The CLX3357 is a storeroom function: the outside lever is always locked and retracts the latch only by key, while the inside lever is always free for egress. That suits a storeroom or a restroom the staff controls, not one an occupant locks from inside. For occupant-controlled privacy with status visibility, the Accentra AUYPL02 of the YPL Series is a Grade 1 privacy cylindrical lock with a visual status indicator. The Falcon H2171 is a Grade 2 interconnected public restroom lock with occupancy indicator and a single cylinder deadbolt.
10) What indicator hardware fits a 1-3/8 inch door when the Corbin Russwin CLX3357 standard build does not?
The CLX3357 is built for 1-3/4 inch to 2 inch doors as standard. For thinner doors, the Accentra D292 is a Grade 2 cylindrical deadbolt with thumbturn and indicator function covering 1-3/8 inch to 1-3/4 inch, and the Arrow E50 covers the same 1-3/8 inch to 1-3/4 inch range as a non-keyed exit deadlock with a vacant/occupied indicator. The Schlage B560 indicator deadbolt is a Grade 2 single cylinder unit with key outside and thumbturn inside for 1-3/8 inch to 1-7/8 inch doors.
11) What is the difference between the V30, V33, V60 and V66 indicator options?
V30 puts a single green/red indicator on the outside only. V33 is the same green/red scheme but reads on both the outside and the inside. V60 is a single outside indicator using white/red instead of green/red, and V66 is the white/red version reading both sides. Pick a double indicator when staff inside the room also need to confirm status; pick white/red where green is already used for something else or a higher contrast read is wanted. All four are offered in 613E dark oxidized satin bronze, 626 satin chrome, and BSP black suede.
12) Is this lock durable enough for a high traffic door, and what is the chassis made of?
Built for it. The lock body is steel with a zinc dichromate treatment for corrosion resistance, and the CLX3300 chassis is UL cycle verified to 20 million cycles (Verification ID V875753). It exceeds 3,100 in-lb abusive locked lever torque and 1,600 lbs offset lever pull, and independent return springs keep the lever from sagging over time. The Lever Release freewheeling design lets a vandal spin the locked outside lever without loading the chassis.
13) Can I add an indicator to an existing lever set instead of replacing it with the CLX3357?
Yes, when the existing lever is sound and only status visibility is missing, an auxiliary indicator deadbolt can be added above it. The Cal-Royal IND90-G2 is an indicator deadbolt with an ADA thumbturn, and the Hager 3216 is a Grade 2 thumbturn by occupancy indicator deadbolt with a 1 inch throw for 1-3/4 inch doors, fire rated. The Arrow E50 is a Grade 2 non-keyed exit deadlock with a VACANT/OCCUPIED indicator outside for 1-3/8 to 1-3/4 inch doors. These require a second bore in the door; the CLX3357 keeps everything in one cylindrical prep at a 2-3/4 inch backset.
14) Is there a Grade 1 indicator option that takes an interchangeable core instead of the CLX3357 conventional cylinder?
The CLX3357 ships with a conventional 6-pin cylinder in the L4 keyway, 0-bitted. If the facility keys on a full size interchangeable core system, the Schlage L460J is a Grade 1 heavy duty small case mortise deadbolt, cylinder by thumbturn, supplied 6-pin FSIC less core with a 5-9/16 inch by 1-1/4 inch face, for 1-3/4 inch doors. It is a deadbolt rather than a latching lever lock, so the door still needs its own latch set.
15) For a patient room or behavioral setting, how does the CLX3357 compare with a one-sided indicator deadbolt?
The CLX3357 is non-handed, Grade 1, and keeps the inside lever free at all times for one-motion egress while the outside is key controlled, and it is offered with single outside indicators in green/red or white/red and with double indicators reading on both sides. The Falcon D271 is a Grade 2 medium duty one-sided deadbolt with an occupancy indicator and a thumbturn inside, which gives occupant control from one face only and no lever operation.
16) How does the lock adjust for door thickness during installation?
Through a patented adjustable push/turn button on the chassis, which is what lets one lock cover the 1-3/4 inch to 2 inch range without swapping parts. Prep is to ANSI/SDI A250.14, and because the lock is non-handed there is no reassembly for swing direction either.
