Sure-Loc Zurich Round Knob Lockset with Adjustable 2-3/8" or 2-3/4" Backset

The Sure-Loc Zurich Round Knob Lockset is a tubular bored lockset for residential doors.

Entry knobs use a single cylinder keyed function with a KW1 keyway (SC1 available) and are keyed alike in sets of four, while Privacy knobs use push-pin locking. The round knob is offered in 15 Satin Nickel and 26 Polished Chrome finishes.

Sure-Loc ZH100-RD 15 – Frequently Asked Questions

1) Does the Sure-Loc Zurich knob fit a door bored for a 2-3/8 inch backset, or do I need to order a specific backset?
One part covers both. The Zurich round knob lockset uses an adjustable latch that sets to either 2-3/8 inch or 2-3/4 inch (60-70mm), which are the two standard residential bore spacings, so you don't have to measure the existing prep before ordering. Set it on the bench to match the cross bore center before you drop it in the door.
2) Which Sure-Loc Zurich model do I order for a bedroom versus a front door versus a closet?
Four functions share the same round knob: ZH100-RD dummy, ZH101-RD entry, ZH102-RD passage, and ZH107-RD privacy. Bedroom and bathroom doors take the privacy version with push-pin locking. Closets, hallways and any door that just needs to latch take the passage. An exterior or unit entry door takes the keyed entry. Dummy is a surface-mounted pull with no latch at all, for a closet leaf or the inactive half of a pair.
3) Can I get Sure-Loc Zurich entry knobs keyed alike so one key works several doors?
Yes. Zurich entry knobs (ZH101-RD) are keyed alike in sets of four, so a single key runs four openings, which covers a typical unit with a front door, back door, garage entry and storage door. They are single cylinder, keyed outside with a turn inside.
4) Will the Zurich entry knob take my existing Kwikset keys, and can I get it on a Schlage keyway instead?
The Zurich entry knob ships on the KW1 keyway, the Kwikset profile, so a locksmith can rekey it to an existing KW1 key system. SC1, the Schlage residential profile, is also available if the rest of the building runs Schlage keys. Pick the keyway that matches your existing keying before you order, since the two are not interchangeable.
5) Is the Sure-Loc Zurich knobset OK for a commercial corridor or apartment common area?
No. The Zurich is a residential-duty tubular knobset, built for interior and unit doors in houses and apartments. For corridors, offices or anything on a commercial spec, step up to a graded cylindrical lock such as the Corbin Russwin CK4310 in Grade 1 or the Dexter C2000 Series in Grade 2. Keep Zurich for the bedroom, bath, closet and passage doors inside the unit.
6) What is an alternative to the Sure-Loc Zurich privacy knob for a bedroom or bathroom door?
The Sure-Loc Zurich privacy knob, model ZH107-RD, uses push-pin locking. Alternatives in the same privacy/bed/bath function include the Dexter C2000 Series Grade 2 privacy ball knob for doors 1-3/8 inch to 1-3/4 inch thick, the Cal-Royal BER20 Grade 3 privacy knob with brass trim over the same thickness range, and the Pamex FTF Baron Grade 3 privacy knob. The Baldwin Estate 5077 Bethpage privacy knob with R027 rose is a decorative option in the same function.
7) The Sure-Loc Zurich entry knob is keyed alike in sets of four - what should I use if I need a classroom or storeroom function instead?
The Sure-Loc Zurich covers dummy, entry, passage, and privacy functions only. For a classroom opening, the Dexter C2000 Series is available as a Grade 2 non-clutching keyed classroom ball knob for 1-3/8 inch to 1-3/4 inch doors. For storeroom, the Sargent 6G04 is a Grade 2 single cylinder storeroom/closet knob lock and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob with a 2-3/4 inch backset.
8) Which knobs look like a substitute for the Sure-Loc Zurich but are not drop-in replacements?
Several knob products are trim or accessories rather than complete bored locksets. The Sargent 28C-KNOB is exit device trim with knob and rose for 1-3/4 inch doors, the Sargent 78-2875 is an outside knob only with B design, and the Imperial USA ED-BKL580 is storeroom function knob trim for an exit device - none of these replace a tubular bored lockset. The Emtek Porcelain knobs are supplied as two knobs per set with a threaded rod, which is a dummy-style mounting, not a latching lockset. The Sure-Loc Zurich is a tubular lockset for bored door preparations.
9) What finishes does the Sure-Loc Zurich round knob come in?
Four: 15 Satin Nickel, 26 Polished Chrome, FBL Flat Black and SB Satin Brass. All four are offered across the dummy, passage, privacy and entry functions, so you can run one finish through a whole unit and still match the right function to each door.
10) Does the Zurich knob need a special door prep, or will it drop into an existing knob hole?
It goes into standard bored (cylindrical) prep, the same round cross bore and edge bore a typical residential knob already uses, so swapping out an old knob normally needs no new drilling. The adjustable latch handles either common backset. What it will not do is fit a mortise pocket or a deadbolt-only bore.
11) How does the privacy lock on the Zurich knob work, and can it be opened in an emergency?
Privacy is push-pin: press the button in the inside knob to lock the bathroom or bedroom door, and it releases when the door is opened from inside. There is no key on the privacy function, it is non-keyed by design, which is why it belongs on bed and bath doors rather than anything you need to secure.
12) What else could I use instead of the Sure-Loc Zurich if I want a round knob with a keyed entry?
Comparable keyed knob entries include the Kwikset 400P-CP Polo, a Grade 3 entry knob listed for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal BER00 entrance/office knob, also Grade 3 and on a Kwikset keyway like the Zurich's KW1. If you want solid brass and a more traditional profile, the Deltana 6171 Round Knob Entry covers 1-3/8 to 2 inch doors.
13) I'm outfitting a whole apartment unit. Can I mix Zurich functions and still have everything match?
Yes, that's the point of the series. Dummy, entry, passage and privacy all use the same Zurich round knob and rose, so a unit with a keyed front door, privacy baths, passage hall doors and a dummy closet leaf reads as one set of hardware. Order the same finish code across all four functions.
14) What knob lockset should I use on a door thicker than standard residential prep?
For thicker doors, the Corbin Russwin CK4310 passage/closet knob lock is Grade 1 and covers 1-3/8 inch to 2 inch, the Corbin Russwin CK4851 entrance/office knob covers the same 1-3/8 inch to 2 inch range, and the Falcon X101 Grade 1 heavy duty passage knobset with interchangeable core goes to 1-3/8 inch to 2-1/4 inch. Among decorative options, the Deltana 6171 Round Knob entry and Deltana 3381 Egg Knob entry both cover 1-3/8 inch to 2 inch. The Sure-Loc Zurich is specified for residential door prep with an adjustable 2-3/8 inch or 2-3/4 inch backset.
15) Is there a passage knob equivalent to the Sure-Loc Zurich ZH102-RD?
Yes. The Sure-Loc Zurich passage knob is model ZH102-RD, a non-keyed round knob on a tubular bored prep. Direct passage/hall/closet counterparts include the Dexter C2000 Series Grade 2 passage ball knob for 1-3/8 inch to 1-3/4 inch doors, the Arrow RK01 Grade 2 ball knob passage lock over the same thickness range, the Bravura Albany round trim Grade 2 passage knobset, and the Pamex FTF Baron Grade 3 passage knob. The Bravura Albany carries round trim, which is closest to the Zurich round knob styling.
16) What dummy knob can I pair with a Sure-Loc Zurich set on a closet or French door?
The Sure-Loc Zurich dummy is model ZH100-RD and carries the same round knob design as the rest of the Zurich functions. If you are matching a different line, the Schlage A170 single dummy trim is a Grade 2 non-keyed dummy for 1-3/8 inch to 1-7/8 inch doors, the BEST 6K Series single dummy trim is a Grade 2 medium duty dummy, the Bravura Biloxi round trim dummy is Grade 2, and the Cal-Royal BA40 Barrington dummy covers 1-3/8 inch to 1-3/4 inch doors. Note that dummy trim has no latch, so it will not hold a door closed.
17) How does the Kwikset 400P Polo entry knob compare to the Sure-Loc Zurich entry knob?
Both are round-style keyed entry knobs for residential doors. The Kwikset 400P Polo entry knob ships with a 6AL latch and RCS round corner strike, and the 400P-CP clear pack version is Grade 3 for doors 1-3/8 inch to 1-3/4 inch. The Sure-Loc Zurich entry knob, model ZH101-RD, is a single cylinder keyed function with a KW1 keyway and an adjustable 2-3/8 inch or 2-3/4 inch backset, and Zurich entry knobs are keyed alike in sets of four.
18) I want a more decorative round knob than the Sure-Loc Zurich for a renovation - what are the options?
The Sure-Loc Zurich is a round knob in Satin Nickel, Polished Chrome, Flat Black, and Satin Brass. For heavier decorative styling, the Baldwin Estate 5000 Baltimore knob is preconfigured with a 2-3/8 inch backset and full lip strike in both passage and privacy, the Baldwin Estate 5011 Colonial passage knob uses a 5058 rose, and the Omnia 434/PA is an egg-shaped knob latchset in solid brass with a 3 inch projection. Emtek offers dummy pairs in Georgetown and Providence crystal knobs for closet and French door use.
19) Is there a keyless alternative to the Sure-Loc Zurich entry knob for a unit I do not want to re-key?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors 1 3/16 inch to 2 inch thick. It requires no key or cylinder, so there is nothing to re-key at turnover. The Sure-Loc Zurich entry knob is a single cylinder keyed function with a KW1 keyway, SC1 also available, and is keyed alike in sets of four.
20) Is the Sure-Loc Zurich knob electronic or does it work with a smart lock system?
It's a purely mechanical tubular lockset, non-electronic. If you need keyless on the same door, look at something like the Lockey 3830 mechanical combination knob lock, which is push-button code entry and fits doors 1-3/16 to 2 inches thick.
21) What Satin Nickel entry knob alternatives match the Sure-Loc Zurich 15 finish?
The Sure-Loc Zurich round knob is offered in 15 Satin Nickel across dummy, passage, privacy, and entry functions. The Callan Roland is a Grade 2 entrance knobset in US15 Satin Nickel. Other entrance options to consider are the Callan Edgewood Grade 2 entrance knobset, the Callan Canova and Callan Santo Grade 3 entrance knobsets, and the Delaney Belton, Galway, and Olivia Grade 3 entrance knobsets.
