Master Lock WL0303BOX – Frequently Asked Questions
1) Will the Master Lock WL03 privacy lever fit a 2-3/8 inch backset, or do I need to know the backset before I order?
Backset is not a decision you have to make with the WL03. The privacy lever ships with a six-way adjustable latch that covers both 2-3/8 inch (60mm) and 2-3/4 inch (70mm) backsets, so one part covers the two standard bores you will find in a residential door. The latch also handles square-corner face plates, rounded-corner face plates, or drive-in installation, which means you can match whatever prep is already cut without buying a separate latch.
2) Is the Master Lock WL03 lever keyed, and can it be locked from the hallway side?
No key, and no outside keyed access. The WL03 is a non-keyed privacy function lockset for bedroom and bathroom doors: it locks from inside the room only. If you need a key on the outside for an office, closet with valuables, or an entry door, this is the wrong function and you want an entrance or storeroom lock instead, such as the Cal-Royal AUS00 Grade 3 entrance/office lever.
3) Is a Grade 3 privacy lever like the Master Lock WL03 good enough for an apartment building or a hotel?
Grade 3 is residential-duty, and that is what the WL03 is rated and catalogued for. For a landlord doing bedroom and bath doors in single-family rentals or light multi-family, it is the right level. For hotel guest rooms, dorms, or anywhere the door cycles hard all day, step up to a Grade 2 or Grade 1 privacy set: the Hager 2540 is a Grade 2 privacy lever with a Withnell design, and the Arrow MK02-TA is a Grade 2 privacy cylindrical lock with a Tudor knob.
4) What is the closest equivalent to the Master Lock WL03 privacy lever from another brand?
The straight cross is the Kwikset 300BRNL Breton privacy lever set, which is also a Grade 3 residential privacy function and fits 1-3/8 to 1-3/4 inch doors. If the opening is heavier use, the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for 1-3/8 to 2 inch doors, and the Baldwin Estate 5103 privacy lever on a 5048 rose is the decorative option. All four are levers; the difference is duty rating and trim style.
5) What should I use instead of the WL03 on a commercial bathroom door that sees heavy traffic?
Step up to a commercial-duty privacy lever. The Hager 2540 with Withnell lever is Grade 2 and fits doors 1-3/8 to 2 inches thick. The Arrow MK02-TA privacy lock is a Grade 1 knob with a fire rating and a 1-3/4 to 2 inch door thickness range. The WL03 is a Grade 3 residential lockset, so on a high-cycle restroom in an office, school, or hotel, one of the commercial-grade options is the one to spec.
6) I need a keyed lever for an exterior or office door, not a privacy set - what takes the place of the WL03 there?
The WL03 is non-keyed, so a keyed entrance lever is a different part. In the same Grade 3 class, the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for doors 1-3/8 to 1-3/4 inches, and the Callan Artino CLN-360201 is a Grade 3 entrance leverset. For a commercial entry, the Hager 2525 is a Grade 2 cylindrical entry lever for doors 1-3/8 to 2 inches, and the Falcon B511CP6D is a Grade 2 medium-duty entry/office lever.
7) Do I have to order a left hand or right hand version of the Master Lock WL03 lever?
Handing is not an ordering choice here. The WL03 is a bored cylindrical lever set with a six-way adjustable latch, so the same part goes on a left or right hand door. That is what makes it workable for a property manager buying a case of them without walking every opening first.
8) Should I use a lever or a knob on interior bedroom and bathroom doors?
A lever is the easier choice for anyone with limited grip, and it is what most renovation and rental work specifies now. The WL03 gives you that in a wave-style lever with a privacy function. A knob set covers the same function, and if you specifically want a knob privacy lock the Arrow MK02-TA is a Tudor knob privacy cylindrical lock at Grade 2. Function is identical; the difference is the operating trim and the duty rating.
9) I need a passage lever to match the Master Lock WL03 privacy lever on the hall and closet doors. What do I use?
Privacy and passage are different functions, so the WL03 will not do a hall or closet door. It locks, and a closet door should not. For the non-locking openings in the same job, the Kwikset 200BRNL Breton passage lever is also Grade 3 residential, or the Callan Asheville is a Grade 3 passage leverset in satin nickel. Pair the finish across both and the openings read as one set even though the functions differ.
10) Can the Master Lock WL03 privacy lever go on a fire rated door?
Bedroom and bathroom privacy is what the WL03 is built for, and privacy function is generally not what a rated opening calls for. If the opening in question is fire rated, specify a lock that carries the rating on record: the Falcon K101 is a Grade 1 fire rated passage cylindrical lock, and the Corbin Russwin CL3110 is a Grade 1 fire rated passage lever. Match the function your code official requires on that door.
11) Does the Master Lock WL03 come with a latch and strike, or do I need to buy those separately?
The latch comes with it, and it is the six-way adjustable type covering 2-3/8 inch and 2-3/4 inch backsets in square corner, round corner, or drive-in form. That is the piece most people worry about matching to an existing door prep. You are ordering a complete privacy lockset for the opening, not a trim-only or dummy piece.
12) Can I key the Master Lock WL03 to match the rest of my building's locks?
There is nothing to key. The WL03 is non-keyed, so it cannot be brought into a master key system or matched to an existing keyway. If you are standardizing a building on one keyway, the keyed openings need a keyed lock: the Cal-Royal AG00 entrance lever comes in a 6-pin Schlage C keyway with a 2-3/8 inch backset, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt. Keep the WL03 for the bedroom and bath doors, which nobody keys anyway.
13) What looks like a substitute for the WL03 but will not work on a bedroom door?
Dummy levers are the common mix-up. The Callan Bentley CLN-BN5051 and the BEST 7KC Series 1DT single dummy trim are dummy-function levers, and the Baldwin Estate 5103 half dummy comes in left hand and right hand versions. Dummy trim is a fixed pull with no latch and no locking mechanism, so it cannot secure a bedroom or bathroom door the way the WL03's privacy function does. Dummy trim belongs on an inactive leaf or a closet door held by a ball catch.
14) Is the Baldwin 5103 privacy lever a drop-in substitute for the WL03?
They serve the same opening but are not the same product. The Baldwin Estate 5103 privacy lever is a privacy/bed/bath function lever supplied with the 5048 rose, an estate-line decorative trim. The WL03 is a Grade 3 privacy lockset with a six-way adjustable latch that fits 2-3/8 inch or 2-3/4 inch backsets and square, rounded-corner, or drive-in latch preps. If the door already has one style of prep and you want a decorative rose, the Baldwin is the direction to go; if you are matching bores across a batch of bedroom doors, the WL03's adjustable latch covers both backsets out of one box.
15) The WL03 will not fit my door thickness - what privacy or passage lever covers a thicker door?
For doors beyond a standard residential thickness, look at the commercial cylindrical levers. The Falcon K101 Grade 1 passage lever covers 1-3/8 to 2-1/4 inches, is fire rated, and uses non-handed levers. The Corbin Russwin CL3110 passage/closet lever is Grade 1, fire rated, and covers 1-3/4 to 2 inches. The Hager 2510 Grade 2 passage lever with Withnell design covers 1-3/8 to 2 inches. These are passage functions, so if the door still needs a thumbturn, the Hager 2540 privacy lock covers 1-3/8 to 2 inches.
16) Can I put a keypad lever on the bathroom door instead of the WL03 privacy lockset?
A keypad set answers a different need. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in a passage function, fitting doors 1-1/8 to 2 inches, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those control who gets in with a code. The WL03 is a non-keyed privacy lockset for interior bedroom or bathroom use, where the point is that the occupant inside locks the door behind them. On a bed or bath door, the privacy function is what most buyers actually want; a keypad suits a controlled room such as a storage or utility space.
17) I am standardizing bedroom and closet levers across a building - what pairs with the WL03 for the non-locking doors?
Match the privacy openings to the WL03 and the corridor, hall, and closet doors to a passage lever of the same class. The Kwikset 200BRNL RDT Breton passage set is Grade 3 with a Passage/Hall/Closet function and a 1-3/8 to 1-3/4 inch door range, which sits in the same residential Grade 3 tier as the WL03. If the trim style matters more than the grade tier, Bravura offers passage leversets in Grade 2 across several designs, including Atlanta and Orlando with round trim and Tampa with square trim.
18) What is the difference between the WL03 and the Arrow MK02-TA privacy lock?
Both are privacy/bed/bath function locks, but the trim and the duty class differ. The WL03 is a Grade 3 lever with a six-way adjustable latch that handles 2-3/8 inch or 2-3/4 inch backsets and square, rounded-corner, or drive-in preps. The Arrow MK02-TA is a Grade 1 privacy cylindrical lock with a Tudor knob, non-keyed, fire rated, for doors 1-3/4 to 2 inches. Lever trim is the choice where ADA operation matters or where a knob is hard to turn; the Arrow is a knob in a heavier duty class.
19) My door needs a lock that staff can release from outside in an emergency - is the WL03 the right function?
For a restroom or patient area that has to be opened from the corridor side, look at an asylum or institutional function. The Dexter C1000 Series asylum lock is Grade 1 with an F87 asylum/institution/utility function for doors 1-3/8 to 2 inches, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob and Schlage C keyway. The WL03 is a residential Grade 3 privacy lockset, which is the standard choice for a home bedroom or bath rather than a supervised facility door.
20) What finishes does the Master Lock WL03 wave lever privacy lockset come in?
Four finishes: 605 Bright Brass, 605 Antique Brass, 716 Aged Bronze, and 619 Satin Nickel. If you are matching existing doors in a unit, 619 satin nickel and 716 aged bronze are the two that pair with most modern residential trim, and the brass options suit older builds. There is no other finish in the WL03 range, so pick from those four for a whole-house match.
