Sure-Loc ZT100 15 – Frequently Asked Questions

1) Will the Sure-Loc Zermatt knob fit a 1-3/8 inch interior door?
Yes. The Zermatt interior version covers doors 1-3/8 inch to 1-3/4 inch (35-45mm), which takes in both the common older 1-3/8 inch interior door and the 1-3/4 inch slab used in newer construction. If you are hanging it on a thicker entry slab, the entry version handles 1-3/4 inch to 2-1/4 inch (45-50mm).
2) What is the difference between the Zermatt dummy, passage and privacy knobs?
Three functions, three jobs. Dummy is a fixed knob with no latch, used on closet or French door leaves that are held by a ball catch or roller. Passage always turns free with a latch but no locking, for halls, closets and utility rooms. Privacy adds the push-pin lock on the inside knob for bedrooms and bathrooms. All three are non-keyed, so none of them takes a key cylinder.
3) Do I need a separate latch and strike with the Sure-Loc Zermatt knob?
A square corner latch and the DB strike pack, part STRDB-SQPK, are available to coordinate the installation, and an optional drive-in latch is offered for door preps bored without a faceplate mortise. Use the drive-in if the edge of the slab has no mortise cut; use the square corner latch and strike where the existing prep is square-cornered.
4) The Sure-Loc Zermatt is non-keyed. What should I order if the door needs a key?
The Zermatt knob is non-keyed in all three of its functions, so it will not cover a keyed opening. For keyed entry, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 400P-CP is a Grade 3 keyed entry knob for the same range, and the Pamex FTF Baron entrance/office is a Grade 3 keyed knob. For heavier keyed duty, the BEST 8K entrance knob is Grade 1 heavy duty.
5) Can the Sure-Loc Zermatt knob be used on a commercial corridor or classroom door?
The Zermatt is specified for residential use, so a commercial opening calls for a graded cylindrical lock instead. The Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with fire rating and a 1-3/8 inch to 2-1/4 inch door range; the Falcon W101 is Grade 2 medium duty, fire rated, with a 2-3/4 inch backset. For a locking commercial function, the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset, and the Dexter C2000 classroom knob is Grade 2 keyed.
6) My door is 2 inches thick. Which knob covers it besides the Sure-Loc Zermatt entry version?
The Zermatt entry version is built for doors 1-3/4 inch to 2-1/4 inch thick. Other knobs that reach 2 inches include the Deltana 6171 Round Knob entry and Deltana 3381 Egg Knob entry, both listed for 1-3/8 inch to 2 inch doors, the Deltana 6112 St. Thomas privacy knob at the same range, and the Corbin Russwin CK4310 Grade 1 passage/closet knob at 1-3/8 inch to 2 inch. The Falcon X101 covers 1-3/8 inch to 2-1/4 inch.
7) What is a close alternative to the Sure-Loc Zermatt privacy knob for a bedroom or bath door?
The Sure-Loc Zermatt ZT102 privacy configuration is a non-keyed tubular knob with push-pin privacy locking. For the same bed/bath opening, the Pamex FTF Baron knob lockset in privacy function is a Grade 3 knob for doors 1-3/8 inch to 1-3/4 inch thick, and the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim, also for 1-3/8 inch to 1-3/4 inch doors. The Dexter C2000 privacy ball knob is a Grade 2 non-clutching privacy knob for the same thickness range.
8) Is there an equivalent passage knob to the Sure-Loc Zermatt for hall and closet doors?
The Zermatt ZT101 passage configuration is a non-keyed tubular knob. Comparable passage knobs include the Pamex FTF Baron in passage function, a Grade 3 knob for 1-3/8 inch to 1-3/4 inch doors; the Arrow MK01, a Grade 2 non-keyed cylindrical passage knob for the same thickness range; and the Corbin Russwin CK4410, a Grade 2 non-keyed Global knob passage/closet lock, also 1-3/8 inch to 1-3/4 inch. The Bravura Albany and Lynchburg round-trim passage knobsets are Grade 2 as well.
9) Which Sure-Loc model numbers do the Zermatt dummy, passage and privacy knobs correspond to?
The Zermatt knob runs as ZT100, ZT101 and ZT102 for the dummy, passage and privacy configurations. Quote the function along with the finish when you order, since both are selected options.
10) What finishes does the Zermatt knob come in, and can I match them across a whole apartment?
Four finishes across all three functions: Satin Nickel (15), Polished Chrome (26), Flat Black (FBL) and Satin Brass (SB). Every finish is offered in dummy, passage and privacy, so a unit can run one finish on the bedroom privacy sets, the hall passage sets and the closet dummy knobs without a mismatch.
11) Is the Zermatt privacy lock keyed alike or does it need a key to release?
Neither. Privacy locking on the Zermatt is a push-pin on the inside knob, so it locks tool-free and there is no keyway anywhere in the set. It is a non-keyed lockset throughout.
12) What is a substitute for the Sure-Loc Zermatt dummy knob on a closet or double door?
The Zermatt ZT100 dummy configuration is a non-operating knob with no latch. Alternatives include the Schlage A170 single dummy trim, a Grade 2 non-keyed knob for doors 1-3/8 inch to 1-7/8 inch; the BEST 6K single dummy trim, Grade 2 medium duty; the Cal-Royal BA40 dummy cylindrical knob for 1-3/8 inch to 1-3/4 inch doors; and the Bravura Biloxi round-trim dummy knobset, Grade 2. Emtek's Hammered Egg and Georgetown dummy knobsets ship as pairs, which suits a double door in one order.
13) Which knobs look like alternatives to the Sure-Loc Zermatt but are not drop-in replacements?
Several knobs in the same size class serve a different purpose. The Sargent 28C-KNOB is exit device trim with knob and rose for 1-3/4 inch doors, not a standalone bored lockset, and the Sargent 78-2875 is an outside knob only. The Imperial USA ED-BKL580 is knob trim in storeroom function. The Emtek Porcelain knobs ship as two knobs per set with a threaded rod. The Lockey 3830 is a mechanical keyless combination knob lock with auto-locking passage function for 1-3/16 inch to 2 inch doors, which is a different mode of operation from push-pin privacy.
14) What alternative to the Sure-Loc Zermatt comes with the latch and strike already in the kit?
For an installer who wants the latch and strike packaged with the knob, the Kwikset 200P Polo passage knob is supplied with a 6AL latch and RCS round corner strike, and the 200P-CP pack includes a round corner adjustable latch and round corner strike. On the keyed side, the Kwikset 400P Polo entry knob includes a 6AL latch and RCS strike. Baldwin's preconfigured Estate 5000 Baltimore knob is offered in passage and privacy with a 2-3/8 inch backset and full lip strike.
15) I need a keyed entrance knob to match the Zermatt knobs on the interior doors of a rental unit. What are the options?
Since the Zermatt is non-keyed across its dummy, passage, and privacy functions, the entrance door needs a separate keyed lockset. Callan offers the Edgewood and Roland as Grade 2 entrance knobsets, with Roland listed in US15 satin nickel, and the Canova and Santo as Grade 3 entrance knobsets. Delaney's Belton, Galway, and Olivia are Grade 3 entrance knobsets, and the Master Lock BC01 biscuit knob is a Grade 3 keyed entry.
16) Is the Sure-Loc Zermatt a battery or electronic lock?
No, it is fully mechanical. The Zermatt is a tubular bored lockset with no electronics, no battery and no wiring, so nothing needs powering and it keeps working in an outage. If you want keyless without electronics, the Lockey 3830 mechanical combination knob lock fits doors 1-3/16 inch to 2 inch.
17) I need a single dummy knob for one side of a closet door. Is the Zermatt dummy a single or a pair?
The Zermatt dummy is ordered as one function selection in your chosen finish, so specify the quantity you need per leaf. Note that some dummy knobs are sold as pairs and some as singles: the Emtek Arts and Crafts Hammered Egg dummy and the Emtek Georgetown crystal dummy are both supplied as pairs, while the Schlage A170 and the Omnia 458/0 are single dummy trim.
18) What are decorative alternatives to the Sure-Loc Zermatt knob for a period interior?
The Zermatt is a plain tubular knob offered in satin nickel, polished chrome, flat black, and satin brass. For a more traditional look in the same functions, the Omnia 434/PA is an egg-shaped solid brass passage latchset with a 3 inch projection, and the Omnia 434/0, 442/00 with a 2-5/8 inch rose, and 458/0 with a 2-3/8 inch backset are solid brass single dummy knob latchsets. Baldwin offers the Estate 5011 Colonial passage knob with 5058 rose and the Estate 5077 Bethpage privacy knob with R027 rose.
