Sure-Loc ZH100-SQ6 15 – Frequently Asked Questions

1) Will the Sure-Loc Zurich square knob fit doors already bored for a 2-3/8 inch backset, or do I need the 2-3/4 inch version?
Either one. The Zurich square knob uses an adjustable latch that sets to 2-3/8 inch or 2-3/4 inch (60-70mm), so the same knob works on both of the standard residential bore layouts. You set the backset at install rather than ordering a specific one.
2) Does the Sure-Loc Zurich 6-pack come with a mix of functions, or six of the same?
The Zurich square knob is ordered by function, and each pack of six is a single function: Dummy, Passage, or Privacy. Pick the function you need for that group of doors and the finish, and you get six of that knob. Turnover crews typically order a privacy pack for bedrooms and baths and a passage pack for halls and closets.
3) What is a comparable non-keyed knob if I need a keyed entry knob on the same doors as the Sure-Loc Zurich Square knobs?
The Sure-Loc Zurich Square knob covers Dummy, Passage, and Privacy functions only and is non-keyed, so it will not secure an entry door. For a keyed entry knob, the Kwikset 400P-CP Polo is a Grade 3 entrance-function knob for doors 1-3/8 inch to 1-3/4 inch thick, and the Cal-Royal BER00 is a Grade 3 entrance/office knob with a Kwikset keyway for the same door thickness range. For a keyed knob at a higher grade, the Dexter C2000 Series entry/office cylindrical ball knob is Grade 2 for 1-3/8 inch to 1-3/4 inch doors.
4) Is the Sure-Loc Zurich Square knob suitable for a commercial corridor, or should I specify something else?
The Sure-Loc Zurich Square knob is a residential tubular knobset, so for commercial traffic the graded cylindrical options are the closer fit. Non-keyed passage equivalents include the Corbin Russwin CK4310, a Grade 1 passage/closet cylindrical lock for doors 1-3/8 inch to 2 inch, and the Falcon X101, a heavy duty Grade 1 cylindrical passage knobset with an interchangeable core and a fire rating for doors 1-3/8 inch to 2-1/4 inch. At Grade 2 there is the Corbin Russwin CK4410 for 1-3/8 inch to 1-3/4 inch doors and the Falcon W101, a medium duty fire rated Grade 2 passage/closet knob with a 2-3/4 inch backset.
5) What should I use instead of the Sure-Loc Zurich Square for a storeroom or classroom door?
The Sure-Loc Zurich Square is limited to dummy, passage, and privacy functions. For storeroom duty, the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset and the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder. For classroom function, the Dexter C2000 Series classroom ball knob is Grade 2 and keyed for doors 1-3/8 inch to 1-3/4 inch.
6) I only need one privacy knob, not a 6-pack. What are the single privacy knob options?
The Sure-Loc Zurich Square is sold in a package quantity of 6. For a single privacy knob, the Pamex FTF Baron is a Grade 3 privacy knob lockset for doors 1-3/8 inch to 1-3/4 inch, the Cal-Royal BER20 is a Grade 3 privacy knob with brass trim for the same thickness range, and the Dexter C2000 Series privacy is a Grade 2 non-clutching cylindrical ball knob for 1-3/8 inch to 1-3/4 inch doors. On the decorative side, the Deltana 6112 St. Thomas and the Baldwin Estate 5077 Bethpage with R027 rose are both privacy/bed/bath knobs.
7) What finishes does the Sure-Loc Zurich square knob come in?
Four: Satin Nickel (15), Polished Chrome (26), Flat Black (FBL), and Satin Brass (SB). All four are offered in Dummy, Passage, and Privacy, so you can carry one finish across every interior door in a unit without mixing brands.
8) How does the privacy lock work on the Sure-Loc Zurich knob, and is there an emergency release?
Privacy Zurich knobs lock with a push pin on the inside knob, the usual bedroom and bathroom arrangement. Privacy sets ship keyed alike in groups of four, so operation is consistent across a group of doors.
9) What is the difference between the Dummy and Passage versions of the Zurich square knob?
The Passage knob has a working latch and turns to retract it, which is what you want on hall, closet, and bedroom doors that need to stay shut. The Dummy knob is fixed trim with no latch and no mechanism, used on the inactive leaf of a pair or on a ball-catch closet door. A single-function pack of six covers either.
10) What is the closest alternative to the Sure-Loc Zurich Square dummy knob for a closet or pantry door?
The Sure-Loc Zurich Square includes dummy function knobs with a square rosette. Comparable dummy trims include the Schlage A170 single dummy, a Grade 2 heavy duty cylindrical non-keyed knob for doors 1-3/8 inch to 1-7/8 inch, the BEST 6K Series single dummy trim at Grade 2 medium duty, the Bravura Biloxi Grade 2 dummy knobset with round trim, and the Cal-Royal BA40 dummy cylindrical knob for 1-3/8 inch to 1-3/4 inch doors. The Omnia 458/0 is a solid brass single dummy latchset with a 2-3/8 inch backset.
11) Which knobs give me a round rosette instead of the square rosette on the Sure-Loc Zurich Square?
The Sure-Loc Zurich Square uses a square rosette profile. For a round rose in a comparable residential knobset, the Bravura Albany and Bravura Lynchburg are Grade 2 passage knobsets with round trim, and the Bravura Dallas is a Grade 2 passage knobset with rectangle trim if you want an angular alternative. The Baldwin Estate 5011 Colonial passage knob uses the 5058 rose, and the Baldwin Estate 5000 Baltimore passage knob uses the 5048 rose with a 2-3/8 inch backset and full lip strike.
12) Are exit device knob trims like the Sargent 28C or Imperial ED-BKL580 substitutes for the Sure-Loc Zurich Square knob?
No. The Sure-Loc Zurich Square is a tubular bored knobset that installs in a standard door prep for dummy, passage, or privacy use. The Sargent 28C-KNOB is exit device trim with knob and rose in a classroom function for 1-3/4 inch doors, and the Imperial USA ED-BKL580 is knob trim in a storeroom function from the ED-500 Series. Both are trim for exit devices rather than standalone bored locksets, so they are not interchangeable with an interior passage or privacy knob.
13) I need a keyless combination knob rather than a privacy push-pin. What is available?
The Sure-Loc Zurich Square privacy knobs use push-pin locking. If you need coded access instead, the Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function for doors 1 3/16 inch to 2 inch thick. It is a different category of hardware from an interior privacy knob and is not a drop-in match for a bedroom or bath prep.
14) For a rental turnover, what single passage knobs compare to the Sure-Loc Zurich Square passage function?
The Sure-Loc Zurich Square passage knobs are non-keyed tubular units with an adjustable 2-3/8 inch or 2-3/4 inch backset. Single passage knobs in the same range include the Pamex FTF Baron Grade 3 passage lockset for doors 1-3/8 inch to 1-3/4 inch, the Arrow MK01 and Arrow RK01 Grade 2 passage cylindrical knob locks for the same thickness range, the Dexter C2000 Grade 2 passage ball knob, and the Kwikset 200P-CP Polo passage knob with a round corner adjustable latch and round corner strike.
15) My doors are thicker than standard residential. Which knobs cover a wider door thickness range than the Sure-Loc Zurich Square?
The Sure-Loc Zurich Square is built for standard residential door preparations with an adjustable 2-3/8 inch or 2-3/4 inch backset. For thicker doors, the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CK4310 Grade 1 passage/closet lock covers 1-3/8 inch to 2 inch, and Deltana knobs such as the 6171 Round Knob entry and 6112 St. Thomas privacy cover 1-3/8 inch to 2 inch.
16) What model numbers are the Sure-Loc Zurich square knob packs?
The Zurich square six-packs run ZH100-SQ6, ZH101-SQ6, and ZH102-SQ6, one per function across the Dummy, Passage, and Privacy range.
17) What are the alternatives if I want a solid brass or decorative knob instead of the Sure-Loc Zurich Square?
The Sure-Loc Zurich Square is a modern square-rosette tubular knob in Satin Nickel, Polished Chrome, Flat Black, and Satin Brass. For traditional or decorative styling, the Omnia 434/PA is an egg-shaped knob latchset in solid brass with a 3 inch projection and the Omnia 442/00 is a single dummy knob latchset with a 2-5/8 inch rose in solid brass. Emtek offers porcelain knobs with threaded rod sold two knobs per set, plus Georgetown and Providence crystal dummy knob pairs and a Hammered Egg dummy pair.
