Arrow QL33SR26D-IC 2-3/4 BS – Frequently Asked Questions

1) What does the asylum function on the Arrow QL33SR actually do, and where would I use it?
Asylum function means there's a cylinder on both sides of the door, so the lever is key-controlled from inside and outside. On the QL33SR the outside lever is locked or unlocked by key, the latchbolt is operated by lever either side when unlocked. That two-cylinder arrangement is what you specify for institutional openings where staff must control access from both directions, behavioral health and detention-adjacent spaces, utility and mechanical rooms. If you only need key control from the corridor side and free egress inside, a storeroom or classroom function is the cheaper, more common choice.
2) Do I have to order the Arrow QL33SR left or right hand?
No handing to specify. The QL33SR is non-handed, so one part number covers both swings and you can stock a single lock for a building with doors going both directions. The Sierra lever design is the trim on it.
3) Will the Arrow QL33SR latch into the strike that's already in my frame?
It should, if that frame carries a standard ANSI strike. The QL33SR ships with a 306 ASA ANSI strike measuring 4-7/8 x 1-1/4 inches and a G71 deadlatch on a 2-3/4 inch backset with a 1/2 inch throw. A 1/2 inch throw needs the strike lip and pocket set at normal ANSI depth, so if your old frame was cut for a 4-7/8 inch strike you're reusing the existing mortise. A frame cut for a 2-3/4 inch T-strike will need to be enlarged.
4) Which keyway should I order the Arrow QL33SR in, and can I put it on my existing masterkey system?
Two ways to order it. The Schlage C keyway version comes with a factory cylinder, solid brass 6-pin, keyed different, with two brass keys, so it works out of the box or can be rekeyed into a Schlage C system you already run. The SFIC less core version ships with no core, which is what you want if your building is on small format interchangeable core and you'll drop your own coded core in. Ordering the less-core version means you must supply the core separately.
5) My doors are 1-3/8 inch. Can I still use the Arrow QL33SR?
Not on the published thickness range, which starts at 1-3/4 inches and runs to 2 inches. For 1-3/8 inch doors in a Grade 1 cylindrical, the Falcon K101 K Series covers 1-3/8 to 2-1/4 inches, and the Dexter C1000 asylum covers 1-3/8 to 2 inches if you need the two-cylinder function specifically. Checking the actual leaf thickness before ordering saves a return here.
6) What is the closest Grade 1 asylum function lever lock to the Arrow QL33SR?
The Dexter C1000 Series asylum lock is the nearest match. Both are Grade 1 cylindrical lever locks with an asylum function, so both give you the key-on-both-sides institutional control the QL33SR provides. The Dexter C1000 asylum is listed for 1-3/8 inch to 2 inch doors, while the Arrow QL33SR covers 1-3/4 inch to 2 inch, so on a thinner leaf the Dexter is the one that reaches. Both are cylindrical bored locks, so the door prep carries over.
7) The door is thicker than 2 inches - what Grade 1 lever will fit?
The Arrow QL33SR is built for 1-3/4 inch to 2 inch doors. For a thicker leaf, the Falcon K101 is a Grade 1 heavy duty cylindrical lock listed for 1-3/8 inch to 2-1/4 inch doors with non-handed levers and a fire rating. It is a passage function, so it carries no key and no locking, which means it substitutes only on an opening that does not need to lock.
8) Is the Arrow QL33SR ADA compliant for a lever height and operation requirement?
It meets ANSI A117.1 Accessibility Code and ADA Section 4.13.9 for acceptable door hardware, and it satisfies the California State Reference Code for levers returning to within 1/2 inch of the door surface. The lever is 4-3/4 inches long, so it's operable without tight grasping or wrist twisting, which is what the ADA hardware clause is testing for.
9) How far does the Arrow QL33SR lever stick out from the door, and will it clear a frame or adjacent wall?
Total projection from the face of the door is 2-17/32 inches. The rose is wrought brass at 3-11/32 inches diameter and the pressure cast zinc lever runs 4-3/4 inches. Those three numbers are what you check against a narrow reveal, a return wall, or a door that swings back against a corridor wall with a stop.
10) What does the freewheeling lever on the Arrow QL Series do for abuse-prone doors?
When the outside lever is locked, it spins freely rather than resisting. Someone hanging on it or forcing it down transmits nothing into the lock body, so the retractor and spindle don't take the load. On institutional, school, and multi-family openings where the lever is the first thing abused, that's the difference between a lock that survives and one that gets replaced. The QL Series also installs with a two screw lockset install.
11) I don't need cylinders on both sides. What should I buy instead of the asylum function lever?
Two cylinders is overkill if the inside only needs free egress. For a corridor door where the outside stays rigid and the inside lever always retracts, look at a Grade 1 storeroom function. For a classroom where a teacher keys the outside lever locked from the corridor, the Cal-Royal AG03 classroom lever is a Grade 2 option on a 2-3/4 inch backset, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors. Dexter's C1000 Series also has Grade 1 classroom and classroom security versions if you need to stay Grade 1.
12) What fasteners and latch come with the Arrow QL33SR, and what else do I need to order?
Wood and machine screws are included, along with the G71 deadlatch on a 2-3/4 inch backset and the 306 ANSI strike. The Schlage C keyway version includes the cylinder and two brass keys. If you order the SFIC less core version, the core is the one thing you supply. Arrow also lists a Q73 spring latch as an alternative to the Q71 dead latch, both 2-3/4 inch backset with 1/2 inch throw, if the opening calls for a plain spring latch rather than a deadlatching one.
13) What is a lower-cost alternative to the Arrow QL33SR for a storeroom door?
For a storeroom opening the Hager 2580 is a Grade 2 cylindrical storeroom lock with the Withnell lever, listed for 1-3/8 inch to 2 inch doors. The Cal-Royal AG05 is also a Grade 2 storeroom lever, with a deadlocking latchbolt, for 1-3/8 inch to 1-3/4 inch doors. Both put the key on the outside only and leave the inside lever free, where the Arrow QL33SR keys both sides. If you want to stay at Grade 1, the QL Series covers storeroom under the QL82 function.
14) Can I use a Corbin Russwin CL3110 in place of an Arrow QL33SR?
Only if the opening does not need to lock. The Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever with a passage/closet function, fire rated, for 1-3/4 inch to 2 inch doors - the same door thickness range as the Arrow QL33SR, and the same Grade 1 cylindrical format. The difference is the function: the CL3110 has no cylinder at all, while the QL33SR is a keyed asylum lock with a cylinder on each side. They match on prep and grade, not on security.
15) What is the difference between the Arrow QL33SR and a Dexter C1000 classroom security lever?
Both are Grade 1 cylindrical lever locks, and both put a key on the inside. The Dexter C1000 classroom security is a clutching keyed lever in the classroom security function, where the inside key controls the outside lever and the inside lever stays free. The Arrow QL33SR is an asylum function: the key operates the latchbolt from either side and neither lever is free. Choose the classroom security lock when staff must be able to exit freely at all times, and the asylum lock when both sides need key control.
16) I need a keyless lever on this opening instead of a keyed lock - what are the options?
The Lockey 2835 is a mechanical pushbutton keyless lever lock with a passage function and ADA compliance, fitting doors from 1 3/16 inch to 2 inch, and the 2835DC is the double combination version of the same lock. The Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors, with the 1150S offering an adjustable backset. All of these run on a combination rather than a cylinder, so they take the opening off the key system that the Arrow QL33SR asylum lock is part of.
17) What Grade 1 entry lever pairs with an Arrow QL33SR on adjacent doors?
For an office or entry opening alongside an asylum-function door, the Dexter C1000 Series entry/office lever is a Grade 1 clutching keyed lock for 1-3/8 inch to 1-3/4 inch doors. It keys the outside only and can be left unlocked for business hours, where the Arrow QL33SR asylum function holds key control on both sides. Both are cylindrical bored locks, so a single 2-1/8 inch bore prep serves either.
18) Can I put an electrified lever on an opening where I would otherwise use an Arrow QL33SR?
The Corbin Russwin CL33903 is a Grade 1 electrified cylindrical lever lock, fail safe, running on 12VAC/DC, for 1-3/4 inch to 2 inch doors - the same door thickness range as the Arrow QL33SR. Fail safe means the lever unlocks when power drops, so it belongs on an opening tied into access control and a power supply. The QL33SR is a mechanical asylum lock that holds its state with no wiring at the door.
19) I need a matching lever with no latch for a fixed leaf next to the locked door - what do I use?
A dummy trim is the right part: it mounts a lever with no latch and no cylinder. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever, which matches the Grade 1 rating on the Arrow QL33SR. The BEST 7KC Series 1DT is the Grade 2 medium duty equivalent, and the Accentra 455LN Augusta is a Grade 1 single dummy in the 5400 Series. None of these operate a latch, so they suit an inactive leaf only.
20) Does a Kwikset Breton lever work as a replacement for an Arrow QL33SR?
No. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors and the 300BRNL Breton is the Grade 3 privacy version over the same thickness range. The Arrow QL33SR is a Grade 1 commercial keyed asylum lock for 1-3/4 inch to 2 inch doors. The Kwikset levers are residential-duty interior sets - they will not meet a Grade 1 spec and neither carries a keyed cylinder.
21) What Grade 2 entry lever uses the same Schlage C keyway as the Arrow QL33SR?
The Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway keyed different, on a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors. The Arrow QL33SR is offered in a Schlage C keyway on a 2-3/4 inch backset, so the two can be keyed into the same system, but note the backsets differ - confirm the bore centerline on the door before ordering across the two.
22) Can I match the Arrow QL33SR to the satin chrome hardware already on my other doors?
Satin chrome (626) is the finish the QL33SR is stocked in, in both the Schlage C keyway and SFIC less core builds. 626 is the standard commercial finish across most institutional and MRO specs, so it lines up with existing closers, exit devices, and hinges already in 626 on the rest of the building.
23) Is a Baldwin Estate 5103 privacy lever a substitute for an Arrow QL33SR?
No. The Baldwin Estate 5103 with the 5048 rose is a privacy lever - a bed and bath function operated by a button, with no cylinder and no key. The Arrow QL33SR is a keyed Grade 1 commercial asylum lock with a cylinder each side. The Baldwin is a residential-styled trim choice for interior doors; it will not carry a key system or a commercial grade requirement.
24) What is the difference between a Grade 1 Design Hardware X75 and the Arrow QL33SR?
The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever, listed for 1-3/4 inch doors. The Arrow QL33SR shares the Grade 1 rating but is a keyed asylum lock and covers 1-3/4 inch to 2 inch doors. Design Hardware also lists the J75, the same flat-lever passage lockset at Grade 2 for 1-3/4 inch doors, if the opening does not carry a Grade 1 requirement.
25) Which lever should I use on an interior office door that only needs passage, not an asylum lock?
For a plain latching door with no locking, the Falcon T101 is a Grade 1 heavy duty cylindrical passage lever with pressure release technology, and the Falcon B101 is the Grade 2 medium duty passage lever with a non-handed design - non-handed like the Arrow QL33SR, so it drops on either swing. At Grade 2 the Hager 2510 passage lock with the Withnell lever covers 1-3/8 inch to 2 inch doors. None of these accept a key, so they only suit openings that never need to be secured.
