Sure-Loc LU100 15 – Frequently Asked Questions

1) Will the Sure-Loc Luna crystal knob fit a 1-3/8 inch interior door?
Yes. The Luna knobset covers doors 1-3/8 inch to 1-3/4 inch (35-45mm) thick, which takes in both older 1-3/8 inch interior doors and standard 1-3/4 inch slabs. Backset is specified as 2-3/8 inch or 2-3/4 inch (60-70mm), so you match it to the prep already bored in the door rather than re-drilling.
2) Is there a keyed entry version of the Sure-Loc Luna knob?
No. The Luna is non-keyed only, offered in dummy, passage, and privacy. Privacy uses a push-pin for bath and bedroom doors, which unlocks from inside but is not a security lock. For a keyed exterior or office door you need a different knobset, such as the Cal-Royal BER00 entrance/office knob lock with a Kwikset keyway or the Dexter C2000 Series keyed entry/office ball knob.
3) Which Luna function do I order for a bedroom, a closet, and a fixed French door panel?
Three separate models. Privacy (LU102 range) for bedrooms and baths, with the push-pin lock. Passage for closets, hallways, and any door that only needs to latch. Dummy for a non-operating half of a French door or a pantry pull, since a dummy has no latch and simply mounts as trim. Models run LU100 / LU101 / LU102 across those functions.
4) Can I use the Sure-Loc Luna knob on apartment corridor or commercial doors?
It is built as residential hardware, tubular construction for bedroom, bath, closet, and interior passage use in homes and multi-family units. For corridor traffic or anything spec'd to a commercial grade, step up to a cylindrical lock like the Corbin Russwin CK4310 (Grade 1 passage) or the Falcon X101 heavy duty Grade 1 passage knobset.
5) I am replacing knobs across a rental unit. Does the Luna drop into the existing holes?
In most cases yes. It is a tubular bored lockset, so it installs into the standard bore and latch prep already in a residential door. Confirm which backset the door was drilled at, 2-3/8 inch or 2-3/4 inch, and order to match. Door thickness has to fall between 1-3/8 and 1-3/4 inch.
6) What is the closest crystal knob alternative to the Sure-Loc Luna knob?
The Emtek Classic Brass Crystal Knobsets are the nearest crystal-knob counterparts. The Georgetown knob and the Providence knob are both offered in dummy function, matching the Luna's dummy option, and Emtek also offers a Porcelain knob set supplied with a threaded rod as two knobs per set. The Luna itself is a solid brass tubular knobset with a crystal knob, offered in Dummy, Passage, and Privacy functions under models LU100, LU101, and LU102.
7) The Luna knob is residential; what should I use on a commercial opening that needs a graded knob lock instead?
The Luna is a residential tubular knobset, so for a graded commercial opening step to a cylindrical lock. In passage function, the Corbin Russwin CK4310 is Grade 1 and fits doors 1-3/8 inch to 2 inch thick, and the Falcon X101 is a Grade 1 heavy duty passage knobset with an interchangeable core, fire rated, for doors 1-3/8 inch to 2-1/4 inch. In privacy, the Dexter C2000 privacy ball knob lock is Grade 2 for doors 1-3/8 inch to 1-3/4 inch.
8) I need a keyed entry knob to match a passage and privacy set - the Luna does not key, so what do I use?
The Luna is non-keyed, covering dummy, passage, and privacy only. For a keyed opening on the same door thickness range, the Kwikset 400P-CP Polo keyed entry knob is Grade 3 for doors 1-3/8 inch to 1-3/4 inch and ships with a round corner adjustable latch and round corner strike; the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for the same thickness range, and the Pamex FTF Baron is offered in Grade 3 entrance/office alongside matching privacy and passage versions.
9) Which knob products look like substitutes for the Luna but will not work on an interior bedroom or bath door?
Exit device and lock trims are not drop-in replacements. The Sargent 28C-KNOB is exit device trim with knob and rose in entrance function 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 knob trim in storeroom function - all trim components rather than a complete interior latchset. The Luna is a complete tubular knobset for passage, privacy, and dummy interior doors.
10) My doors are thicker than 1-3/4 inch - what knob covers that if the Luna will not?
The Luna fits doors 1-3/8 inch to 1-3/4 inch. For thicker doors, the Deltana 6112 St. Thomas privacy knob and 6171 Round knob entry both cover 1-3/8 inch to 2 inch, the Corbin Russwin CK4310 Grade 1 passage lock covers 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch.
11) Will the Luna knob work in a door with no mortised latch pocket?
Yes, a drive-in latch is available for the Luna, so it can go into a bored hole without chiseling a faceplate mortise. That is the quicker option on remodel work and on doors where the existing latch was drive-in. The standard faceplate latch is the choice when the door is already mortised for one.
12) What other crystal knobs could I use instead of the Sure-Loc Luna?
For the same glass-knob look, Emtek's Classic Brass Crystal knobsets are the closest alternatives we carry, in the Georgetown and Providence styles (dummy pair), plus Emtek Porcelain Knobs with threaded rod if you want ceramic rather than crystal. The Luna differs in that it is offered as a full set of functions, dummy, passage, and privacy, on a solid brass tubular chassis.
13) For a rental turn, what are the budget-grade knob alternatives to the Luna in matching functions?
For plain-finish turns across passage, privacy, and dummy, the Pamex FTF Baron series covers Grade 3 passage and Grade 3 privacy for doors 1-3/8 inch to 1-3/4 inch, the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim for the same range, and the Cal-Royal BA40 is a dummy knob cylindrical lock in the Barrington BA series, also 1-3/8 inch to 1-3/4 inch. The Luna covers those same three functions with a crystal knob and push-pin privacy.
14) Is a single dummy trim the same thing as the Luna dummy knob I should order for a closet door?
Dummy options differ in how many knobs come with them. The Schlage A170 is a single dummy trim, Grade 2 and heavy duty, for doors 1-3/8 inch to 1-7/8 inch, and the BEST 6K single dummy trim is Grade 2 medium duty. The Emtek Arts and Crafts Hammered Egg dummy and the Emtek Georgetown crystal dummy are both supplied as pairs. Confirm single versus pair against your door before ordering the Luna dummy.
15) What decorative knob lines besides Luna offer passage and privacy in a matching design?
Baldwin Estate covers both in matching rose trim: the 5000 Baltimore knob comes as a passage lock with 2-3/8 inch backset and full lip strike and as a privacy lock with the 5148 rose, and the 5077 Bethpage is offered in privacy with the R027 rose while the 5011 Colonial covers passage with the 5058 rose. Bravura also spans the range with Albany and Lynchburg Grade 2 passage knobsets and the Biloxi Grade 2 dummy.
16) I need a keyless combination knob for a rental instead of a push-pin privacy knob - what is the option?
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. That replaces a key or push-pin with a code entry, whereas the Luna uses a push-pin privacy mechanism for tool-free locking on bath and bedroom doors.
17) Is the Luna dummy knob sold as a single or a pair?
The dummy is listed by function and finish only, four finishes, so what varies is the finish and not a single-versus-pair choice. If you specifically need two knobs for both faces of an inactive door, Emtek's crystal dummy knobsets are catalogued as pairs, and the Schlage A170 is a single dummy trim.
18) Is the crystal knob just a cap, or is the lock body brass?
The Luna pairs a crystal knob with solid brass construction in the knob body, running on a tubular chassis. It is a mechanical lock with no electronics, so nothing to wire or batteries to change.
