Sure-Loc DU100-SQ6 15 – Frequently Asked Questions

1) Will the Sure-Loc Durango square knobset fit a 1-3/8 inch interior door?
Yes. The Durango square knobset fits doors from 1-3/8 to 1-3/4 inches (35-45mm) thick, which covers both the common older 1-3/8 inch interior door and standard 1-3/4 inch doors. The backset is adjustable, so it drops into either a 2-3/8 or 2-3/4 inch bore center on standard residential prep.
2) Is the Sure-Loc Durango knobset keyed, and what does keyed alike in sets of 4 mean?
The Durango square knobset is non-keyed. It comes in Dummy, Passage and Privacy functions only, none of which take a key. The keyed-alike-in-sets-of-4 note applies where a keyed function exists in the Durango line; on the six-pack you are buying non-keyed units, so there is no key to match. If you need keyed entry on an exterior or lockable door, this is not the part.
3) Which function do I order for bedrooms versus hallways versus a closet door that doesn't latch?
Three choices on the Durango square knob. Passage for hallways, closets and any door that needs to latch but not lock. Privacy for bedrooms and bathrooms, where you get an interior push or turn lock. Dummy for a fixed, non-turning knob on a false door, a closet with a ball catch, or the inactive leaf of a pair. Each function is sold as its own six-pack, so a mixed-function job needs separate packs.
4) Is the Sure-Loc Durango knobset rated for commercial use in an office building or school?
No. The Durango square knobset is a residential tubular lockset. For commercial corridors, classrooms and other high-traffic openings, step up to a cylindrical lock with a stated ANSI grade, like the Grade 2 Falcon W101 passage knob or the Grade 1 Falcon X101, or the Grade 1 Corbin Russwin CK4310 passage lock.
5) Will the Durango knob go into the existing holes in my door, or do I have to re-drill?
Sure-Loc bored locks are built for standard residential door preparation, so if the door already carries a typical tubular knobset the Durango drops into the same bore. The adjustable backset handles either standard hole center, and the 1-3/8 to 1-3/4 inch thickness range covers ordinary interior doors. What does need checking is the latch face and strike prep, since square-corner and round-corner faces are not interchangeable without touching the mortise.
6) What can I use instead of the Sure-Loc Durango square knobset when the opening needs a keyed entry knob?
The Durango square knobset is offered only in Dummy, Passage and Privacy functions and is non-keyed, so it cannot secure an entry door. For a keyed knob on the same 1-3/8 inch to 1-3/4 inch door thickness range, the Kwikset 400P-CP is a Grade 3 entrance knob, and the Cal-Royal BER00 is a Grade 3 entrance/office knob with a Kwikset keyway. For a heavier keyed opening, the BEST 8K Series is a Grade 1 heavy duty entrance knob lock with a single cylinder.
7) The Durango knobset does not cover my door thickness. What knob options handle thicker doors?
The Durango square knobset fits doors 1-3/8 inch to 1-3/4 inch thick. For thicker stock, the Falcon X101 Grade 1 cylindrical passage knobset covers 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CK4310 Grade 1 passage lock covers 1-3/8 inch to 2 inch, and Deltana knobs such as the 6171 Round Knob entry and the 3381 Egg Knob entry cover 1-3/8 inch to 2 inch.
8) Is there a Grade 1 or Grade 2 commercial alternative to the Sure-Loc Durango knobset for a passage door?
The Durango square knobset is a residential tubular knobset, so on a commercial corridor spec the graded cylindrical alternatives are the ones to look at. The Corbin Russwin CK4310 is a Grade 1 non-keyed passage/closet cylindrical knob lock for doors 1-3/8 inch to 2 inch thick, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset, fire rated, for doors 1-3/8 inch to 2-1/4 inch. In Grade 2, the Corbin Russwin CK4410 passage/closet lock and the Dexter C2000 passage ball knob both cover 1-3/8 inch to 1-3/4 inch doors.
9) What is the closest equivalent to the Sure-Loc Durango privacy knob for a bed or bath door?
The Durango square knobset in Privacy function is a non-keyed tubular knob for doors 1-3/8 inch to 1-3/4 inch thick. Comparable privacy knobs over the same door thickness range include the Pamex FTF Baron in Grade 3, the Cal-Royal BER20 in Grade 3 with brass trim, and the Dexter C2000 privacy ball knob in Grade 2. If the door runs thicker, the Deltana 6112 St. Thomas privacy knob covers 1-3/8 inch to 2 inch.
10) Which of these knob locks look like substitutes for the Durango knobset but are not?
Several knob items in the same family are not interchangeable with a Durango bored knobset. 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, so neither is a complete bored lockset. The Imperial USA ED-BKL580 is knob trim for the ED-500 series. The Lockey 3830 is a mechanical keyless combination knob lock, which changes how the door operates rather than matching a plain passage or privacy knob. Emtek porcelain knobs ship as two knobs with a threaded rod rather than as a latching set.
11) I need a fire rated knob lock instead of the Durango knobset. What should I look at?
For an opening where the knob lock itself must carry a fire rating, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock in passage/closet function with a 2-3/4 inch backset and a fire rating, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core and a fire rating for doors 1-3/8 inch to 2-1/4 inch thick.
12) What should I use instead of the Durango knobset on a classroom or storeroom door?
The Durango square knobset is non-keyed and does not offer institutional functions. For those openings, the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, 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 lock is Grade 2 and keyed for doors 1-3/8 inch to 1-3/4 inch thick.
13) Can I mix Satin Nickel and Flat Black in one Sure-Loc Durango six-pack?
No. Each pack is a single finish and a single function. Satin Nickel (15) and Flat Black (FBL) are both offered across Dummy, Passage and Privacy, giving six orderable combinations, but a pack contains six matching units. For a multi-unit turn or a whole house, order one pack per finish and function you need.
14) I need matching knobs on a whole apartment turnover. Does buying a six-pack keep everything consistent?
That's what the contractor six-pack is for. Six matching Durango square knobs in one finish and function, coordinating with the rest of the Sure-Loc Durango line, so bedroom privacy sets and hall passage sets read the same across the unit. Satin Nickel or Flat Black. Buy one Privacy pack for the bed and bath doors and one Passage pack for halls and closets and the whole unit matches.
15) Is a dummy knob pack the same as a passage set without the latch?
Functionally, no. A dummy knob is surface mounted trim with no latch and no turning action, so the door needs a ball catch, magnet or roller to stay shut. A passage set has a working latch that holds the door closed. Both are available in the Durango square six-pack. Comparable single dummy trims include the Schlage A170 and the BEST 6K single dummy.
16) How does the Sure-Loc Durango dummy knob differ from other dummy knob trims?
The Durango square knob in Dummy function is a tubular-style residential knob for doors 1-3/8 inch to 1-3/4 inch thick, sold six to a pack. Among other dummy options, the Schlage A170 is a Grade 2 single dummy trim rated heavy duty for doors 1-3/8 inch to 1-7/8 inch, the BEST 6K single dummy trim is Grade 2 medium duty, and the Cal-Royal BA40 dummy knob covers 1-3/8 inch to 1-3/4 inch. Emtek sells its dummy knobs as pairs, such as the Arts and Crafts Hammered Egg dummy pair, which suits a double door where both sides need a knob.
17) I need square-rose knobs to match a modern interior. What alternatives have non-round trim?
The Durango square knobset pairs a hollow mushroom-shaped formed brass knob with square trim and comes in Satin Nickel and Flat Black. Among other knobsets, the Bravura Dallas passage knobset uses rectangle trim in a US4 Satin Brass finish; most other comparable knobsets, including the Bravura Albany and Lynchburg passage knobsets and the Biloxi dummy knobset, use round trim.
18) If I only need one or two knobs rather than the Durango six-pack, what comparable passage knobs are there?
The Durango square knobset is packaged six to a set. For single-unit passage knobs in the same residential range, the Kwikset 200P Polo passage knob ships with a 6AL latch and RCS round corner strike, the Pamex FTF Baron passage knob is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, and the Baldwin Estate 5000 Baltimore passage knob comes preconfigured with a 2-3/8 inch backset and full lip strike.
19) How does the Durango square knob compare to solid brass decorative knobs for an interior remodel?
The Durango square knob is a hollow mushroom-shaped knob in formed brass, offered in Satin Nickel and Flat Black. On the decorative side, the Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection, the Omnia 442/00 is a solid brass single dummy knob latchset with a 2-5/8 inch rose, and the Baldwin Estate 5011 Colonial passage knob uses the 5058 rose. Those are single decorative sets rather than a matched multi-pack.
20) Are there ball knob alternatives to the Durango square knob for a rental turnover?
The Durango square knobset uses a hollow mushroom-shaped knob with square trim. If a plain ball knob suits the units better, the Arrow RK01 is a Grade 2 non-keyed passage ball knob lock for doors 1-3/8 inch to 1-3/4 inch, the Arrow MK01 is a Grade 2 non-keyed passage knob lock over the same thickness range, and the Dexter C2000 passage ball knob is Grade 2, non-clutching and non-keyed for 1-3/8 inch to 1-3/4 inch doors.
21) What's the difference between the Durango square knob and a round or ball knob set?
The Durango is a hollow, mushroom-shaped knob on a square rose, formed brass construction. The shape of the rose is what changes the look on the door; the tubular chassis and standard residential prep are the same idea either way. If you want a round rose instead, the Bravura Albany and Lynchburg passage knobsets use round trim, and the Dexter C2000 series is a ball knob.
22) What are the Sure-Loc Durango square knob model numbers?
The six-pack models are DU100-SQ6, DU101-SQ6 and DU102-SQ6, covering the three functions in the Durango square knob line. Add the finish code when ordering: 15 for Satin Nickel, FBL for Flat Black.
