Arrow MLX82-SR-26D – Frequently Asked Questions

1) Will the Arrow MLX82 storeroom lever fit a standard 2-1/8 inch bore, or do I have to re-prep the door?
No new prep needed on a standard commercial door. The MLX82 goes into a standard 2-1/8 inch cross bore with a 2-3/4 inch backset, and the latch front measures 1-1/8 x 2-1/4 inches. Doors from 1-3/8 to 1-3/4 inches thick are covered as standard. If the existing lock uses a 2-3/8 inch backset, the bore is in the wrong spot for this one.
2) Will the Arrow MLX82 latch into my existing ANSI strike, or do I need to cut the frame?
It ships with a 306 ASA ANSI strike, 4-7/8 x 1-1/4 inches, which is the standard commercial frame cutout. If your frame already has an ANSI 4-7/8 inch prep, the strike drops straight in. The latch is a stainless R21 deadlatch with a 1/2 inch throw, so it needs a proper strike lip and box depth; a residential round-corner strike will not accept it.
3) Do I need to order the Arrow MLX82 handed for a left or right hand door?
No handing to specify. The MLX82 is non-handed, so one part number covers left and right hand doors and both swings. For a property manager stocking spares across a building, that means a single lock on the shelf works on any opening.
4) Should I order the Arrow MLX82 with a conventional cylinder or SFIC less core?
Depends on who keys the building. The conventional cylinder version is a solid brass 6-pin, cut to the Arrow AR or Schlage CS keyway, and comes with two brass keys. The IC version is SFIC less core, which means no cylinder in the box; you supply your own small format interchangeable core, which is what you want if a facility already runs SFIC and rekeys by swapping cores instead of pinning cylinders. Both cylinder choices are offered in all four finishes: 605 bright brass, 626 satin chrome, 613 satin bronze oil-rubbed, and BSP black suede.
5) Can I get several Arrow MLX82 locks keyed alike so one key opens all my storage rooms?
Yes. Keying is a required selection on the order: keyed different (the standard), keyed alike for multiple locks, or none if you are taking a less-cylinder option. Pick keyed alike and there is a field to enter your key code, so new locks can be cut to a key system already running in the building.
6) What is the closest Grade 2 storeroom lever lock to the Arrow MLX82 from another brand?
The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and it fits 1-3/8 inch to 1-3/4 inch doors, the same door thickness range the Arrow MLX82 covers. Both are storeroom function, so the outside lever stays locked and the latchbolt is retracted by key outside or by the inside lever. The Hager 2580 with the Withnell lever is also a Grade 2 storeroom cylindrical lock, and it takes a wider 1-3/8 inch to 2 inch door range if you have thicker doors in the same building.
7) What storeroom lever should be used on a door thicker than 1-3/4 inches?
The Arrow MLX82 is built for 1-3/8 inch to 1-3/4 inch doors. For a thicker leaf, the Hager 2580 storeroom lever with the Withnell design is a Grade 2 cylindrical lock rated for 1-3/8 inch to 2 inch doors. If the opening is a 1-3/4 inch to 2 inch door and the spec calls for Grade 1, the Corbin Russwin CL3100 series covers that thickness range in a vandal resistant cylindrical lever, though the CL3110 is passage function and carries no cylinder.
8) What is the difference between the Arrow MLX82 storeroom lock and an entrance or office function lever?
On the Arrow MLX82 the outside lever is always locked and the latchbolt is retracted only by key outside or by turning the inside lever, so the door cannot be left unsecured by mistake. An entrance/office lever such as the Falcon B511CP6D, a Grade 2 medium duty cylindrical lock, or the Hager 2525 Grade 2 commercial cylindrical entry lock, lets the outside lever be left unlocked for the business day. The Cal-Royal AUS00 is the same idea at Grade 3 with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors. Choose storeroom when the room must relock itself every time the door closes.
9) What lever lock replaces the Arrow MLX82 on a classroom door?
The MLX82 is storeroom function, which keeps the outside lever locked at all times. A classroom door usually needs the outside lever unlocked and relocked by key from the corridor: the Cal-Royal AG03 classroom lever is Grade 2 in the AG Series with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, matching the 2-3/4 inch backset the MLX82 uses. The Dexter C1000 classroom lock is the Grade 1 option with a clutching lever for 1-3/8 inch to 1-3/4 inch doors, and the C1000 classroom security version adds key control of the latch from inside the room.
10) What lock should be used instead of the Arrow MLX82 when the door has to unlock on a fire alarm?
The Arrow MLX82 is a mechanical Grade 2 storeroom lock with no electrical connection - the outside lever is released only by key. For an opening tied into access control or a fire alarm release, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC for 1-3/4 inch to 2 inch doors, available with the NZ lever and D rose. Fail safe means the outside lever unlocks when power drops, the opposite of the always-locked behavior of a storeroom lock.
11) Can a residential lever set be used in place of the Arrow MLX82 in a commercial building?
The Arrow MLX82 is a Grade 2 commercial cylindrical lockset that meets ANSI/BHMA F86 for storeroom function. Residential-duty levers such as the Kwikset 200BRNL Breton passage and the Kwikset 300BRNL Breton privacy are Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Master Lock BC Series RL01 return style keyed entry lever is Grade 3 entrance function. Those are built to a lighter cycle standard and none of them is storeroom function, so they will not hold a spec that calls for a Grade 2 commercial storeroom lock. The Cal-Royal AG05 Grade 2 storeroom lever is the closer swap if you need to stay commercial.
12) Does the Arrow MLX82 accept a Schlage keyway, and what else uses one?
Yes. The Arrow MLX82 cylinder is solid brass 6 pin and is offered in both the Arrow AR and Schlage CS keyway, keyed different as standard, with keyed alike available. Among comparable commercial levers, the Cal-Royal AG00 entrance lever and AG03 classroom lever both use a 6-pin Schlage C keyway keyed different, so they can be brought onto the same key system. The AG00 runs a 2-3/8 inch backset while the AG03 uses 2-3/4 inch, which is the backset the MLX82 latch is prepped for.
13) Is a Grade 2 storeroom lever enough for a commercial building, or do I need Grade 1?
Grade 2 is the commercial medium duty tier and the MLX82 is built for commercial use, with a FreeWheeling lever that spins under force instead of transferring abuse into the lock. For offices, storage, and back-of-house doors in a normal-traffic building it is the right level. On a high-abuse opening (school corridor, stadium, public restroom entry) buyers usually step up to Grade 1: ZenSupply carries the Corbin Russwin CL3100 Series, a Grade 1 vandal resistant cylindrical lever, and the Falcon K Series K101, a Grade 1 heavy duty cylindrical lock rated for 1-3/8 to 2-1/4 inch doors.
14) How far does the Arrow MLX82 lever stick out, and will it clear a door frame or adjacent wall?
Total projection from the face of the door is 2-17/32 inches (64.5mm). The lever itself is pressure cast zinc, 4-3/4 inches long, on a wrought brass rose 3-11/32 inches in diameter. Those numbers matter on a door in a tight corner or next to a return wall, and the rose diameter tells you how much of the old lock's wear ring it will cover on a retrofit.
15) Can I put the Arrow MLX82 on a hollow metal door as well as a wood door?
Both. Wood and machine screws are included, so the same lock covers a wood door and a hollow metal or steel door without a separate fastener kit. Installation is a two-screw lockset, which is why crews use it for volume replacement work.
16) I need a lever that stays unlocked all the time, not a storeroom lock. What should I get instead?
Storeroom is the wrong function for that: the MLX82's outside lever is permanently locked and only a key or the inside lever retracts the latch. For a corridor, closet, or any door that should just push open, you want passage function. ZenSupply carries the Falcon B101, a Grade 2 non-handed cylindrical passage lever, and the Accentra 5301LN Augusta, a Grade 2 passage/closet cylindrical lever. If you need privacy (bath or bed, inside thumbturn with emergency release) that is a third function again.
17) Which lever lock should be used if the door needs to stay unlocked instead of key-controlled?
The Arrow MLX82 is a keyed storeroom lock, so the outside lever is always locked. For an opening that only needs latching with free operation from both sides, the Falcon B101 is a Grade 2 medium duty cylindrical passage lever with a non-handed design, and the Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever in the 5300 Series. Where the spec calls for Grade 1 passage, the Falcon K101 is a heavy duty non-handed passage lock that is fire rated and fits 1-3/8 inch to 2-1/4 inch doors.
18) Is a dummy lever a substitute for the Arrow MLX82?
No. A dummy trim has no latch and no cylinder at all - it is a pull mounted to the face of the door. The BEST 7KC single dummy trim is Grade 2 medium duty and non-keyed, and the BEST 9K 1DT is the Grade 1 heavy duty equivalent. The Arrow MLX82 is a keyed cylindrical lock with a single cylinder and an R21 deadlatch on a 2-3/4 inch backset. Dummy trim is for the inactive leaf of a pair or a closet door that latches by magnet, never for a secured storeroom.
19) Is there a keyless alternative to the Arrow MLX82 for a storage room?
The Arrow MLX82 uses a solid brass 6 pin cylinder in the Arrow AR and Schlage CS keyway with two brass keys. If you want to stop issuing keys, the Lockey 2835 is a mechanical pushbutton keyless lever lock that is ADA compliant and fits 1-3/16 inch to 2 inch doors, and the 2835DC adds a double combination. The Lockey 1150 is the heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors, with an adjustable backset version. The Delaney LP250 is a Grade 2 electronic keypad leverlock if you want a battery-powered code instead of a mechanical one. All of these are passage-style keyless entry rather than a key-controlled storeroom lock, so a lost code means a combination change rather than a rekey.
20) Which Grade 2 lever locks pair with the Arrow MLX82 to finish a suite of doors?
The Arrow MLX82 covers the keyed storeroom openings at Grade 2 on 1-3/8 inch to 1-3/4 inch doors. To carry the same grade through the rest of the suite, the Hager 2510 Withnell passage lever and the Hager 2540 privacy lever with the Withnell design are Grade 2 for 1-3/8 inch to 2 inch doors, and the Hager 2525 is the Grade 2 commercial entry lever. Staying inside one series through the passage, privacy and entry doors keeps the lever shape and rose consistent down the corridor.
21) Does the Arrow MLX82 use a single cylinder, and is there a thumbturn on the inside?
Single cylinder, key outside only. There is no thumbturn and no inside keyway; the inside lever is always free. That is deliberate on a storeroom lock, since anything that lets someone leave the outside lever unlocked defeats the point of the function.
22) What finishes does the Arrow MLX82 Sierra lever come in?
Four: 605 bright brass, 626 satin chrome, 613 satin bronze oil-rubbed, and BSP black suede powder. For matching an existing building, 626 satin chrome is the common commercial standard and the one most back-of-house openings already wear.
