Sure-Loc ZT100-SQ SB – Frequently Asked Questions

1) Which Zermatt function do I order for a bedroom or bathroom door?
Order the Privacy function, model ZT102-SQ. It uses push-pin locking on the inside knob. Use Passage (ZT101-SQ) for hall, closet and utility doors where no lock is wanted, and Dummy (ZT100-SQ) as fixed trim on a door that does not latch, such as one leaf of a closet pair. None of the three are keyed.
2) Can I use the Sure-Loc Zermatt knob on an exterior entry door with a key?
No. The Zermatt square knob is non-keyed only, in Dummy, Passage and Privacy. For a keyed entry knob, look at the Kwikset 400P-CP Polo keyed entry knob (Grade 3, 1-3/8 to 1-3/4 inch doors) or, for heavier commercial use, the BEST 8K Series Grade 1 entrance knob lock.
3) Is the Zermatt knob suitable for a commercial corridor or a school?
No. It is a residential tubular knobset, sized for homes, apartments and rental interiors. For commercial traffic, go to a cylindrical lockset such as the Corbin Russwin CK4310 Grade 1 passage knob (1-3/8 to 2 inch doors) or the Falcon X101 Grade 1 passage knobset (1-3/8 to 2-1/4 inch doors).
4) I need a privacy knob but my doors are up to 2 inches thick. What else works?
The Zermatt privacy knob covers 1-3/8 to 1-3/4 inches in its interior configuration, so a 2 inch slab is outside that. Deltana's 6112 St. Thomas privacy knob is listed for 1-3/8 to 2 inch doors, and the Baldwin Estate 5077 Bethpage is another privacy knob option.
5) Will the Sure-Loc Zermatt square knob fit a 2 inch thick door?
Zermatt square corner interior knobs are specified for doors 1-3/8 inch to 1-3/4 inch thick, with entry configurations reaching 1-3/4 inch to 2-1/4 inch. For a thick door in a non-keyed passage function, Corbin Russwin CK4310 covers 1-3/8 inch to 2 inch in Grade 1 and Falcon X101 covers 1-3/8 inch to 2-1/4 inch in Grade 1 heavy duty. Deltana 6112 St. Thomas privacy knob is rated 1-3/8 inch to 2 inch if the door needs a privacy function at that thickness.
6) My interior doors have round corner latch prep. Is the Sure-Loc Zermatt ZT-SQ still the right knob?
No. The Zermatt ZT-SQ is built for square corner latch prep and pairs with the STRDB-SQPK square corner DB strike pack. If the existing mortise in the door edge is radius cut, the Kwikset 200P Polo passage knob ships with a 6AL latch and RCS round corner strike, and the 200P-CP version comes with a round corner adjustable latch and round corner strike. Sure-Loc also offers the Zermatt knob in round corner form, so the door prep is what drives the choice rather than the knob design.
7) What is the closest alternative to the Sure-Loc Zermatt ZT102-SQ privacy knob if I need the same bed and bath function from another brand?
For a privacy knob on bedroom and bathroom doors, the Dexter C2000 Series privacy cylindrical ball knob is a Grade 2 non-keyed privacy/bed/bath lock for doors 1-3/8 inch to 1-3/4 inch thick, and the Pamex FTF Baron knob lockset in privacy function is Grade 3 for the same 1-3/8 inch to 1-3/4 inch thickness range. Cal-Royal BER20 is another Grade 3 privacy knob lock, supplied with brass trim. The Zermatt ZT102-SQ differs in that it is a square corner design with push-pin privacy locking and pairs with the STRDB-SQPK square corner DB strike pack.
8) I need a keyed entry knob, not a privacy or passage knob. What should I order instead of the Zermatt ZT-SQ?
The Zermatt square corner knob is non-keyed, offered only in dummy, passage, and privacy functions, so it will not secure an exterior or lockable office door with a key. For keyed operation, Kwikset 400P-CP is a Grade 3 keyed entry knob for doors 1-3/8 inch to 1-3/4 inch thick supplied with a round corner adjustable latch and round corner strike, Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway, and Dexter C2000 entry/office is a Grade 2 keyed ball knob for the same thickness range.
9) The Zermatt ZT-SQ is residential. What is the commercial-grade equivalent for an apartment corridor or school?
The Zermatt square corner knob is a residential tubular knobset. For higher-traffic commercial openings, Corbin Russwin CK4310 is a Grade 1 non-keyed passage/closet cylindrical knob lock for doors 1-3/8 inch to 2 inch thick, Falcon X101 is a heavy duty Grade 1 cylindrical passage knobset that is fire rated and covers 1-3/8 inch to 2-1/4 inch doors, and BEST 8K Series is a Grade 1 heavy duty entrance knob lock. On the Grade 2 tier, Arrow MK01 and Falcon W101 are cylindrical passage knob locks, the W101 with a 2-3/4 inch backset and a fire rating.
10) I need a knob that locks with a key from outside a storage room. Does the Zermatt ZT-SQ do that?
It does not. The Zermatt square corner knob is non-keyed, so its privacy function locks only by push-pin from the inside. Storeroom duty calls for a keyed cylinder: Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, and Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset. Corbin Russwin CK4851 is a Grade 1 entrance/office knob lock with a conventional cylinder for doors 1-3/8 inch to 2 inch thick.
11) Can I get the Zermatt knob with a drive-in latch instead of a faceplate?
Yes, a drive-in latch option is available on the Zermatt square corner knob. Drive-in latches skip the mortised faceplate and are quicker on new-construction slabs; if the existing door is already mortised for a faceplate, stay with the square corner faceplate latch.
12) What finishes does the Zermatt square knob come in, and can I match them across every function?
Three finishes: 15 Satin Nickel, FBL Flat Black, and SB Satin Brass. All three are offered in Dummy, Passage and Privacy, so a whole unit or floor of doors can be finished consistently no matter which function each opening needs.
13) Does the Zermatt knob come with a strike, or do I order that separately?
The square corner DB strike pack, STRDB-SQPK, is listed as an optional accessory rather than part of the knob, so add it if you need the strike and dust box for a fresh jamb. Reusing a sound existing square corner strike is fine.
14) Is there a keyless combination knob I can use instead of the Zermatt ZT-SQ on a rental unit door?
The Zermatt square corner knob is a mechanical non-electronic knobset with no code entry. If you want keyless code access on a knob, the Lockey 3830 is a mechanical keyless combination knob lock with auto-locking passage function for doors 1 3/16 inch to 2 inch thick. It is a different operating method entirely, so the door prep and thickness should be confirmed before swapping.
15) What is an alternative to the Zermatt ZT100-SQ dummy knob for a closet or inactive door?
The ZT100-SQ is the dummy function of the Zermatt square corner knob, a non-latching pull. Comparable dummy trims include the Schlage A170 single dummy trim, a Grade 2 heavy duty non-keyed knob for doors 1-3/8 inch to 1-7/8 inch, the BEST 6K Series single dummy trim in Grade 2 medium duty, Cal-Royal BA40 dummy cylindrical knob for 1-3/8 inch to 1-3/4 inch doors, and Bravura Biloxi with round trim in Grade 2. Omnia 434/0 and 442/00 are solid brass single dummy knob latchsets if you want a brass traditional look rather than a square corner rose.
16) What passage knob works instead of the Zermatt ZT101-SQ if I want a traditional or decorative look?
The ZT101-SQ is the passage function of the Zermatt square corner knob with a square rose and knob shape. For a traditional profile, Baldwin Estate 5011 Colonial is a passage knob with a 5058 rose, the Baldwin 5000 Baltimore passage lock comes preconfigured with a 2-3/8 inch backset and full lip strike, and Omnia 434/PA is a solid brass egg-shaped passage latchset with a 3 inch projection. Bravura Albany and Lynchburg are Grade 2 passage knobsets with round trim, and Bravura Dallas is a Grade 2 passage knobset with rectangle trim in US4 satin brass.
17) Is a knob trim for an exit device the same thing as the Zermatt ZT-SQ knobset?
No. The Zermatt ZT-SQ is a complete tubular bored knobset with its own latch, sold in dummy, passage, and privacy functions. Sargent 28C-KNOB is exit device trim with a knob and rose for 1-3/4 inch doors, Sargent 78-2875 is an outside knob only in B design, and Imperial USA ED-BKL580 is knob trim in storeroom function for the ED-500 Series. Those are lever or knob trims that mount to a separate exit device and will not operate a bored interior door on their own.
18) What is a dummy knob for, and do I get one knob or two?
A dummy knob is fixed trim with no latch, used for pulling a non-latching door such as a closet or French door leaf. The Zermatt ZT100-SQ dummy is sold as a single-knob configuration per SKU, so order two if you need both faces. If you want a pair in one box, Emtek lists dummy knobsets sold as a pair, such as the Arts & Crafts Hammered Egg dummy pair.
19) What is the difference between the Sure-Loc Zermatt ZT-SQ and Emtek dummy knob pairs?
The Zermatt ZT100-SQ dummy is a square corner knob from the Ridgecrest collection in satin nickel, flat black, or satin brass. Emtek dummy knobsets are sold as pairs: the Arts and Crafts Hammered Egg dummy pair and the Classic Brass Crystal Georgetown and Providence dummy pairs, plus Emtek porcelain knobs with threaded rod supplied two knobs per set. The Emtek items give you both faces of a door in one order and use decorative egg, crystal, or porcelain knob shapes rather than a square profile.
