Sure-Loc MS100-SQ 15 – Frequently Asked Questions

1) Will the Sure-Loc Mesa Square lever fit my existing door prep?
For a standard bored residential prep, yes. The Mesa Square leverset ships with an adjustable latch that sets to either a 2-3/8 inch or 2-3/4 inch backset, the two backsets used on residential doors, and it fits doors 1-3/8 to 1-3/4 inches thick. It is a tubular bored lockset, so it drops into the usual 2-1/8 inch cross bore prep without new boring.
2) Do I have to order the Sure-Loc Mesa lever handed for a left or right hand door?
No. Handing is reversible on the Mesa Square lever, and the change is made without tools, so one part number covers left hand and right hand doors. That is useful for a property manager buying in bulk: you stock one lever and sort out swing at the door.
3) Which Mesa Square lever function do I use for a bedroom versus a front door versus a closet?
Bedroom or bathroom takes Privacy or Push-Button Privacy (locks from inside, no key). A front or exterior door takes Entry or Push-Button Entry, which are keyed single cylinder. A hall or closet door takes Passage, which is non-locking. A door that only needs a lever for looks, like an inactive French door leaf, takes Dummy. The models run MS100-SQ, MS101-SQ, MS102-PBSQ, MS102-SQ, MS107-PBSQ and MS107-SQ across those functions.
4) Can I key the Sure-Loc Mesa entry levers to my existing Kwikset keys?
The keyed Mesa cylinders use the KW1 keyway, which is the standard Kwikset residential profile, so they accept a KW1 blank. SC1 is also available if the building is keyed on Schlage-profile residential keys. Keyed cylinders come keyed alike in sets of four, so a unit can run one key across several doors out of the box. Matching an existing key bitting means having a locksmith rekey the cylinder.
5) The Mesa Square is residential - what should I use on a commercial opening instead?
The Sure-Loc Mesa Square is a residential tubular bored lockset. For commercial openings where an ANSI grade is specified, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock that is fire rated and fits doors 1-3/8 inch to 2-1/4 inch thick, and the Hager 2525 is a Grade 2 commercial cylindrical entry lock for doors 1-3/8 inch to 2 inch thick. Both are non-handed or commercial-prep designs rather than residential retrofits.
6) My door is 2 inches thick - can I still use the Mesa Square?
The Sure-Loc Mesa Square fits doors 1-3/8 inch to 1-3/4 inch thick, so a 2 inch door is outside its range. For thicker doors, the Deltana 6201 Manchester, 6411 Morant and 6431 Linstead entry levers all cover 1-3/8 inch to 2 inch, the Hager 2510 Grade 2 passage lever covers 1-3/8 inch to 2 inch, and the Dexter C1000 asylum lock covers 1-3/8 inch to 2 inch.
7) What is a comparable residential passage lever to the Sure-Loc Mesa Square if I need a different lever style?
The Sure-Loc Mesa Square covers passage among its functions with a square-shape lever on a residential tubular bored lockset. For a similar residential passage lever in a different look, the Kwikset 200BRNL Breton passage lever set is a Grade 3 passage/hall/closet lever fitting doors 1-3/8 inch to 1-3/4 inch thick, the same door thickness range the Mesa Square fits. The Callan Asheville CLN-AH5011 is another Grade 3 passage leverset option.
8) Will the Mesa Square entry lever work on a classroom or storeroom door, or do I need something else?
The Sure-Loc Mesa Square is offered in Dummy, Entry, Passage, Privacy, Push-Button Entry and Push-Button Privacy - there is no classroom or storeroom function in the line. For those openings, the Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway and 2-3/4 inch backset, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 classroom lever is a Grade 1 keyed clutching lock.
9) I key everything on Schlage C - does the Mesa Square fit, or should I order a different lever?
The Sure-Loc Mesa Square ships on a KW1 keyway with SC1 also available, and keyed cylinders come keyed alike in sets of 4. If you standardize on a 6-pin Schlage C keyway instead, the Cal-Royal AG00 entrance lever is supplied with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset, and the Arrow MK33-BD-CS is a conventional cylinder in Schlage C keyway.
10) What finishes does the Sure-Loc Mesa Square lever come in, and are they the same across all functions?
Four finishes: 15 Satin Nickel, 26 Polished Chrome, SB Satin Brass and FBL Flat Black. Dummy, Passage, Privacy and Entry are offered in all four. The two push-button functions, Push-Button Entry and Push-Button Privacy, come in Satin Nickel and Flat Black only, so if you are matching a whole house in Satin Brass or Polished Chrome, use the standard Entry and Privacy versions.
11) What is the difference between the Mesa Privacy lever and the Push-Button Privacy version?
Both lock a bed or bath door from the inside. The Push-Button Privacy (MS102-PBSQ) uses a push button in the inside rose to engage the lock, while the standard Privacy (MS102-SQ) uses a turn. Same story on the entry side: Push-Button Entry (MS107-PBSQ) locks by button, keyed Entry (MS107-SQ) by the outside key and inside turn. Both are single cylinder keyed on the entry versions.
12) What square-trim leverset alternatives are there if I want to keep the squared look of the Mesa Square?
The Sure-Loc Mesa Square uses square trim and a square lever across all six functions. If you want the same squared aesthetic from another line, the Bravura Tampa BVR-BV333702 is a Grade 2 passage leverset with square trim. Bravura's Atlanta, Orlando and Miramar passage leversets in the same Grade 2 family use round trim instead.
13) Mesa Square push-button entry versus a keypad or code lever - what is the difference?
The Sure-Loc Mesa Square Push-Button Entry is a mechanical push-button lever with a keyed KW1 cylinder and no electronics. If you want code entry instead of a key, the Delaney LP250 is an electronic keypad leverlock rated Grade 2, the Emtek Classic Keypad Leverset is a keypad option, and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination that fits doors 1-1/8 inch to 2 inch thick.
14) I need a privacy lever for a bedroom or bath - is the Mesa Square the right pick or is there an alternative?
The Sure-Loc Mesa Square includes both Privacy and Push-Button Privacy functions on a residential tubular lockset. Alternatives in the same privacy role include the Kwikset 300BRNL Breton privacy lever set, a Grade 3 privacy/bed/bath lever for doors 1-3/8 inch to 1-3/4 inch thick, the Hager 2540 Grade 2 privacy cylindrical lock with Withnell lever for doors 1-3/8 inch to 2 inch, and the Baldwin Estate 5103 privacy lever with 5048 rose.
15) What is the difference between the Mesa Square dummy lever and a Baldwin or Emtek dummy?
All three are dummy trim with no latch. The Sure-Loc Mesa Square dummy is part of a residential line that also offers entry, passage, privacy and push-button functions in matching square trim, in Satin Nickel, Polished Chrome, Flat Black and Satin Brass. The Baldwin Estate 5103 half dummy is handed and ordered as a specific left hand or right hand part with the 5048 rose, while the Emtek Arts and Crafts and Cortina dummies are sold as pairs. The Mesa Square itself is reversible handing, so the trim family does not need a hand called out.
16) Is a lever like the Corbin Russwin CL3110 a substitute for the Mesa Square passage lever?
Not for the same opening. The Sure-Loc Mesa Square is a residential tubular bored lockset for doors 1-3/8 inch to 1-3/4 inch thick with an adjustable 2-3/8 inch to 2-3/4 inch backset. The Corbin Russwin CL3110 passage/closet lock is a Grade 1 vandal resistant cylindrical lever that is fire rated and fits doors 1-3/4 inch to 2 inch, so it suits a thicker commercial door leaf. The Design Hardware X75 passage lever is likewise a Grade 1 lock built for 1-3/4 inch doors only.
17) I want a keyed entry lever with a deadbolt on the same door - what pairs with or replaces the Mesa Square entry?
The Sure-Loc Mesa Square Entry is a single cylinder keyed lever without an integrated deadbolt. If you want the deadbolt in one package, the Callan Bennett CLN-BN3001R is a Grade 3 entrance leverset supplied as a deadbolt combo. For a keyed entry lever alone in a different line, the Callan Artino CLN-360201 and the Cal-Royal AUS00 entrance/office lever with a solid brass forged body are both Grade 3 entrance functions, and the AUS00 fits doors 1-3/8 inch to 1-3/4 inch like the Mesa Square.
18) For a high-traffic multi-family corridor door, is there a heavier alternative to the Mesa Square?
The Sure-Loc Mesa Square is built for residential use with a solid die-cast lever. Where traffic calls for a heavier cylindrical lock, the BEST 9K Series 1DT dummy trim and the Falcon T101 passage lever are both Grade 1 heavy duty, the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever, and the BEST 7KC Series 1DT dummy trim is a Grade 2 medium duty option in between.
19) I need a matching dummy lever for an inactive French door leaf. Does Mesa offer one?
Yes, the Mesa Square dummy (MS100-SQ) is a surface-mounted lever with no latch, made to match the working Mesa levers on the same opening. It is available in all four finishes. If you need a handed half dummy in a different style, the Baldwin Estate 5103 is offered in left hand and right hand half dummy versions.
