Sure-Loc ZH100-RD6 15 – Frequently Asked Questions

1) Will the Sure-Loc Zurich knob fit doors bored at 2-3/4 inch backset, or only 2-3/8?
Both. The Zurich round knobset uses an adjustable latch that sets to either a 2-3/8 inch or 2-3/4 inch backset (60-70mm), so it drops into either of the two standard residential bores without ordering a different part. That is the main reason it works well for turnover crews hitting a mix of older and newer doors in the same building.
2) What is the difference between the Dummy, Passage, and Privacy versions of the Zurich knobset?
Three separate functions, ordered separately. Dummy is a surface-mounted knob with no latch, for a closet or inactive leaf of a pair that you only need to pull. Passage latches but never locks, for halls and closets. Privacy has push-pin locking on the inside for bedrooms and bathrooms, with quick release from the outside. Model numbers run ZH100-RD6, ZH101-RD6 and ZH102-RD6.
3) What is a comparable round knob if I need a keyed entry function instead of dummy, passage, or privacy?
The Sure-Loc Zurich round knobset is non-keyed and covers only dummy, passage, and privacy functions, so it will not serve an exterior or lockable office door. For a keyed opening, the Kwikset 400P-CP Polo keyed entry knob is a Grade 3 entrance knob for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for the same door thickness range. If the door needs a commercial-grade keyed knob, the Corbin Russwin CK4851 is an entrance/office cylindrical lock with a conventional cylinder for 1-3/8 inch to 2 inch doors.
4) The Zurich knobs are residential - what should I specify for a commercial corridor or classroom door instead?
The Sure-Loc Zurich round knobset is a residential tubular knobset. For commercial traffic, the Falcon X101 is a heavy duty Grade 1 cylindrical passage knobset with an interchangeable core, fire rated, and fits 1-3/8 inch to 2-1/4 inch doors. The Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock with a Global knob for 1-3/8 inch to 2 inch doors. Where the opening needs to stay locked, 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 ball knob is a Grade 2 keyed classroom function.
5) What is the closest equivalent to the Sure-Loc Zurich knobset if I need one function at a time rather than a multi-function pack?
The Zurich round knobset ships six knobsets per pack covering dummy, passage, and privacy. To buy the same functions individually, the Dexter C2000 series splits them out: the C2000 passage ball knob and the C2000 privacy ball knob are both Grade 2, non-keyed, and fit 1-3/8 inch to 1-3/4 inch doors. Pamex covers the same spread in its Grade 3 Baron FTF line, with the FTF30 in passage and the FTF10 in privacy for 1-3/8 inch to 1-3/4 inch doors.
6) My doors have a 2-3/4 inch backset - what other knobs fit besides the Zurich?
The Sure-Loc Zurich round knobset uses an adjustable 2-3/8 inch or 2-3/4 inch backset, so it covers both standard residential preps out of the box. Among fixed-backset options, the Falcon W101 passage/closet knob lock is built for a 2-3/4 inch backset and the Sargent 8XG04 storeroom knob lock also uses a 2-3/4 inch backset. If the prep is 2-3/8 inch, the Baldwin Estate 5000 Baltimore passage lock comes preconfigured with a 2-3/8 inch backset and full lip strike, and the Kwikset 200P-CP Polo passage knob ships with a round corner adjustable latch and round corner strike.
7) How many knobs come in a Sure-Loc Zurich 6-pack?
Six knobsets per pack, all one function and one finish per pack. So a whole-house or unit turnover typically means ordering more than one pack: a Passage pack for halls and closets, a Privacy pack for bedrooms and baths, and Dummy where there is no latch to catch.
8) What finishes does the Zurich round knob come in?
Four: Satin Nickel (15), Polished Chrome (26), Flat Black (FBL), and Satin Brass (SB). All four are offered in each of the Dummy, Passage, and Privacy functions, so you can hold one finish across every door in a unit regardless of which function that door needs.
9) Can I use the Zurich privacy knob on a bathroom door where someone might get locked in?
Yes, that is what it is built for. The Zurich privacy knob locks with a push pin on the inside and releases instantly, so a bedroom or bathroom door can be opened from the hall side in an emergency without a key or a tool hunt. It is non-keyed, so there is no cylinder to defeat and no key to lose.
10) I need a single dummy knob, not a six pack. What else is there?
The Zurich dummy only ships as a six-pack, which suits a builder but not a one-door repair. For a single dummy knob, the Schlage A170 single dummy trim (Grade 2, 1-3/8 to 1-7/8 inch doors), the BEST 6K single dummy trim, or the Cal-Royal BA40 dummy knob for 1-3/8 to 1-3/4 inch doors cover the same job one at a time. Emtek's Hammered Egg and Georgetown dummy knobs ship as a pair if you need both faces of a door.
11) Which dummy knobs are alternatives to the Zurich dummy function on a closet or false door?
The Zurich round knobset covers a dummy function among its three. Comparable dummy trims include the Schlage A170 single dummy, a Grade 2 heavy duty cylindrical non-keyed knob for 1-3/8 inch to 1-7/8 inch doors, and the BEST 6K single dummy trim, a Grade 2 medium duty knob. For a decorative interior, the Bravura Biloxi round trim dummy knobset is Grade 2, and Omnia offers solid brass dummy latchsets such as the 458/0 with a 2-3/8 inch backset and the 442/00 with a 2-5/8 inch rose. The Cal-Royal BA40 Barrington dummy knob fits 1-3/8 inch to 1-3/4 inch doors.
12) What looks like a substitute for the Zurich knobset but will not work as a drop-in interior lockset?
A few knob products are trim only or special-purpose and will not replace a Sure-Loc Zurich tubular knobset on a bored interior door. The Sargent 28C-KNOB is exit device trim with knob and rose for 1-3/4 inch doors, and the Sargent 78-2875 is an outside knob only with B design - both attach to an exit device, not a standalone bored prep. The Imperial USA ED-BKL580 is likewise knob trim in a storeroom function for the ED-500 exit device series. The Emtek Porcelain knobs ship as two knobs with a threaded rod, so they need separate latching hardware. The Lockey 3830 is a mechanical keyless combination knob lock for 1 3/16 inch to 2 inch doors, a different animal from a push-pin privacy knob.
13) Is there a privacy knob alternative to the Zurich if I want a decorative or solid brass look?
The Zurich privacy knob uses push-pin locking in a plain round silhouette. For a more traditional appearance in the same privacy/bed/bath function, the Deltana 6112 St. Thomas knob fits 1-3/8 inch to 2 inch doors, the Baldwin Estate 5077 Bethpage privacy knob uses an R027 rose, and the Baldwin Estate 5000 Baltimore privacy lock comes preconfigured with a 5148 rose, 2-3/8 inch backset, and full lip strike. The Cal-Royal BER20 is a Grade 3 privacy knob with brass trim for 1-3/8 inch to 1-3/4 inch doors.
14) Will the Zurich round knob match the rest of my interior hardware?
The Zurich is a plain round knob on a round rose, part of the Sure-Loc Modern collection, so it reads as a clean contemporary knob rather than a colonial or egg shape. In Satin Nickel or Satin Brass it sits alongside most current interior hardware; Polished Chrome and Flat Black are the two harder-edged options. If your existing doors carry a traditional egg or crystal knob, the Omnia 434 egg-shape or Emtek Providence crystal lines are closer in style.
15) Is the Zurich knobset electronic or does it need any wiring?
Purely mechanical. The Zurich is a non-electronic tubular knobset, no wiring, no batteries, no power transfer hinge. If you want keyless code entry on an interior door instead, the Lockey 3830 mechanical combination knob lock is the non-electric alternative and fits doors 1-3/16 to 2 inches thick.
