Cal-Royal MAY00-10B-RH – Frequently Asked Questions

1) Will the Cal-Royal MAY00 lever lock fit a 1-3/8 inch wood door?
Yes. The MAY00 entrance/office leverset covers a door thickness range of 1-3/8 to 1-3/4 inches, and it's built for both wood and metal doors. That range is the common older interior thickness at the bottom end and standard commercial at the top, so most existing openings fall inside it. Anything thicker than 1-3/4 inches needs a different lock.
2) Will the MAY00 latch into the strike already in my frame?
It depends what's cut in. The MAY00 ships with a round corner full lip strike measuring 1-3/4 x 2-1/4 inches, which is the ordinary commercial cylindrical strike footprint. A T-strike is optional, and a round corner deadbolt strike at 1 x 2-1/4 inches is offered. Cal-Royal uses the same strikes and latchbolts across its knob and leversets, so if you're swapping another Cal-Royal cylindrical set the frame prep carries over.
3) How does the entrance/office function on the Cal-Royal MAY00 actually work?
Both sides lock or unlock by key from the outside or by push button on the inside. That's the office pattern: staff button the lever down at the end of the day, or key it from the corridor. It's a single cylinder lock, keyed outside only. If you need the lever to stay locked outside at all times while the inside always exits free, that's a storeroom function, not this one.
4) Does the Cal-Royal MAY00 have to be ordered handed?
Order it left hand or right hand. The MAY00 is offered in LH and RH, and while the unit is described as reversible for right and left handed doors, the Mayfair configuration is the exception to that. Get the handing right on the order rather than planning to flip it in the field.
5) Can the Cal-Royal MAY00 be keyed alike with the rest of my building?
Yes. Keying is chosen at order time, keyed different or keyed alike. The cylinder is a standard KW 5-pin Kwikset keyway, rekeyable, and it accepts master keying and construction keying. Weiser and Schlage C keyways are available on special factory request, so if the property is already standardized on Schlage C you can ask for that rather than rekeying on site.
6) Is a Grade 3 lever lock like the Cal-Royal MAY00 enough for a commercial office door, or do I need Grade 1?
Grade 3 to ANSI A156.2 is a light duty rating. The MAY00 suits offices, suites and tenant doors that see moderate traffic, and it's built with an all metal body, a solid brass forged body and a solid filled handle grip. For a high-traffic corridor, a classroom or an institutional opening, step up to Grade 1: the Dexter C1000 Series entry/office lever is a Grade 1 equivalent function covering 1-3/8 to 1-3/4 inch doors, and the Falcon B511CP6D is a Grade 2 entry/office middle ground.
7) My doors are 2 inches thick. Can I still use the Cal-Royal MAY00?
No. The MAY00 tops out at 1-3/4 inches. For a 2 inch door look at the Hager 2525 Grade 2 commercial cylindrical entry lock, which covers 1-3/8 to 2 inches, or the Deltana 6201 Manchester entry lever at 1-3/8 to 2 inches. If you want Grade 1 on a thick door, the Corbin Russwin CL3100 Series runs 1-3/4 to 2 inches.
8) What entrance/office lever lock steps up from Grade 3 without going to Grade 1?
The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever lock with Entrance/Office function, the same function the Cal-Royal MAY00 provides at Grade 3. It is the middle option between the MAY00 and the Grade 1 Dexter C1000 entry/office lever.
9) I need a fire rated lever lock for the same opening as a Cal-Royal MAY00 - what are my options?
The Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock carrying a fire rating, and the Falcon K101 is a Grade 1 heavy duty cylindrical lock with a fire rating. Both are passage/closet function, so neither locks - if the opening needs a key, the MAY00 keyed entrance/office function does not transfer to them.
10) Can I substitute a Bravura or Baldwin passage leverset for a Cal-Royal MAY00?
No. The MAY00 is keyed with a single cylinder and locks both sides by key outside or push button inside. The Bravura Atlanta, Orlando and Tampa leversets and the Baldwin Estate 5103 passage lever are all passage/hall/closet function, which means they latch but never lock. They are trim-matching partners for the non-locking openings on the same job, not replacements for the keyed door.
11) What is the difference between a Cal-Royal MAY00 and a Hager 2580 storeroom lever?
Function. The MAY00 is Entrance/Office - both sides lock or unlock by key outside or push button inside, so staff can leave the door unlocked during the day. The Hager 2580 with Withnell lever is Grade 2 storeroom, which stays locked at all times and requires a key on every entry. For a tenant suite or office door you want the entrance/office behavior; for a supply or mechanical room, storeroom.
12) What lever lock should I use on a classroom door instead of a Cal-Royal MAY00?
The Dexter C1000 classroom lever is Grade 1 over 1-3/8 inch to 1-3/4 inch, and the C1000 classroom security version covers the same door range with a keyed inside cylinder as well. Both share the MAY00 door thickness range of 1-3/8 inch to 1-3/4 inch, so the door prep depth is the same. The MAY00 itself is an entrance/office function and does not provide classroom lockdown.
13) I need a matching passage or privacy lever on the other doors. What pairs with the Cal-Royal MAY00?
For coordinated trim on the interior side, Cal-Royal offers the leverset in the Chelsie Series. If you're filling out an opening set from other brands we carry, the Callan Asheville is a Grade 3 passage leverset and the Callan Artino is a Grade 3 entrance leverset, both the same duty class as the MAY00. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 as well and cover the same 1-3/8 to 1-3/4 inch door range.
14) Is there another Grade 3 keyed lever lock comparable to the Cal-Royal MAY00?
Yes. The Callan Artino is a Grade 3 entrance leverset, and the Master Lock BC Series RL is a Grade 3 return style keyed entry lockset. Both sit at the same ANSI grade as the Cal-Royal MAY00, which is Grade 3 with an Entrance/Office function keyed as a single cylinder.
15) Is a Kwikset 200BRNL Breton lever a substitute for a Cal-Royal MAY00?
Not for a keyed opening. The Kwikset 200BRNL Breton is Grade 3 over a 1-3/8 inch to 1-3/4 inch door range - the same grade and door range as the MAY00 - but it is passage/hall/closet function and does not take a key. The Kwikset 300BRNL Breton at the same grade and range is privacy, locked by thumbturn only. The MAY00 is the keyed single cylinder member of that door range.
16) If I want a keyless entry lever instead of a keyed Cal-Royal MAY00, what are the alternatives?
The Lockey 2835 mechanical pushbutton keyless lever lock is ADA compliant and fits 1-3/16 inch to 2 inch doors, with a double combination version in the 2835DC. The Delaney LP250 is a Grade 2 electronic keypad leverlock. The MAY00 uses a rekeyable 5-pin Kwikset KW keyway and a push button inside, so it still needs keys issued and tracked.
17) The opening needs a deadbolt as well as a lever - what is the alternative to a Cal-Royal MAY00?
The Callan Bennett is a Grade 3 entrance leverset supplied as a deadbolt combo, the same grade as the MAY00. The MAY00 is a single cylinder entrance/office lockset on its own, though the specification does include a round corner deadbolt strike at 1 inch by 2-1/4 inch if a separate deadbolt is being added to the door.
18) Does a Cal-Royal MAY00 need to be ordered by hand like a Baldwin 5103 half dummy?
No. The MAY00 is reversible for right and left handed doors, and is stocked in left hand and right hand configurations across US3 polished brass, US15 satin nickel and US10B dark oxidized satin bronze. The Baldwin Estate 5103 half dummy is a fixed hand item, ordered as a left hand or a right hand part with no reversing in the field.
19) Can I use a Cal-Royal MAY00 on a psychiatric or utility room door?
For asylum and institutional openings the Dexter C1000 asylum lock is Grade 1 over 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a Schlage C keyway on a ball knob. The MAY00 is entrance/office function with a push button inside, which is the wrong behavior for a room that must be key operated from both sides.
20) I want the same entrance function as a Cal-Royal MAY00 but with a knob instead of a lever - what works?
The Arrow HK11-BB is a Grade 2 turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder, covering 1-3/8 inch to 1-3/4 inch doors - the same door thickness range the MAY00 fits. The MAY00 is a lever handle type, which is what ADA openings generally call for.
21) What finishes does the Cal-Royal MAY00 lever lock come in?
Three: US3 polished brass, US15 satin nickel and US10B dark oxidized satin bronze, each in left and right hand. The body is wrought brass, bronze or stainless steel and the levers are zinc casting plated to match the trim finish, so the lever and rose read as one finish across an opening.
22) Is the Cal-Royal MAY00 a lever or a knob, and is it rated for commercial use?
Lever handle, and it's classified commercial. The MAY00 is a keyed cylindrical entrance/office leverset, Grade 3 under ANSI A156.2. A lever rather than a knob is what most facilities specify for accessible openings and it's what building occupants expect on office doors.
23) What matches a Cal-Royal MAY00 on the closet and dummy doors of the same job?
The Callan Bentley is a Grade 2 dummy lever and the Callan Asheville is a Grade 3 passage leverset, alongside the Callan Artino Grade 3 entrance leverset. The BEST 7KC Series single dummy trim is a Grade 2 non-keyed medium duty dummy, and the BEST 9K Series 1DT is the Grade 1 heavy duty equivalent. Pair a dummy or passage lever on the non-locking openings with the keyed MAY00 on the entry door.
