Sure-Loc DU100 15A – Frequently Asked Questions

1) Will the Sure-Loc Durango knob fit my existing door prep with a 2-3/8 inch backset?
Yes. The Durango knob uses an adjustable latch that covers both standard residential backsets, 2-3/8 inch and 2-3/4 inch (60-70mm), so it drops into either bore layout without ordering a specific latch. Door thickness range is 1-3/8 inch to 1-3/4 inch (35-45mm), which covers standard interior and exterior residential doors.
2) Which Durango function do I order for a bedroom, a bathroom, and a front door?
Sure-Loc Durango knobs come in five functions. Passage for bedrooms, hallways and closets where no lock is needed. Privacy for bathrooms and bedrooms that need an inside push-button with no key. Entry for a keyed exterior door. Entry/Deadbolt Combo when you want the keyed knob and a matching deadbolt together on an exterior opening. Dummy is a non-turning pull for a closet or inactive leaf, with no latch at all.
3) Can I get several Sure-Loc Durango entry knobs on one key for a rental unit?
Yes, and that is how they ship. Durango keyed sets come keyed alike in groups of 4, so one key operates all four doors. The cylinder is single cylinder with a KW1 keyway (SC1 is also available), which is the common Kwikset-profile residential keyway a locksmith can duplicate off the shelf.
4) The Durango knob is a residential lockset - what should I use on a commercial opening instead?
The Sure-Loc Durango knob is a residential tubular knobset. For commercial door hardware, the BEST 8K Series is a Grade 1 heavy duty entrance-function single cylinder knob lock, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset. On the Grade 2 side, the Corbin Russwin CK4851 is an Entrance/Office cylindrical knob lock with a conventional cylinder for doors 1-3/8 inch to 2 inch.
5) Does the Durango knob fit a 2 inch thick door, and what fits if it does not?
The Sure-Loc Durango knob is built for doors 1-3/8 inch to 1-3/4 inch thick. For a thicker door, the Deltana 6171 Round Knob entry and Deltana 3381 Egg Knob entry both cover 1-3/8 inch to 2 inch, the Corbin Russwin CK4310 Grade 1 passage knob covers 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 passage knobset with interchangeable core covers 1-3/8 inch to 2-1/4 inch.
6) What is the closest alternative to the Sure-Loc Durango knob for a keyed entry door on a Kwikset KW1 key system?
The Sure-Loc Durango knob uses a KW1 keyway with SC1 available and is offered in an Entry function. If a different brand is needed on the same key system, the Cal-Royal BER00 is an Entrance/Office knob lock with a Kwikset keyway, Grade 3, and fits doors 1-3/8 inch to 1-3/4 inch. The Kwikset 400P-CP Polo keyed entry knob is also a Grade 3 entrance knob for 1-3/8 inch to 1-3/4 inch doors and ships with a round corner adjustable latch and round corner strike.
7) The Durango has an adjustable backset - which comparable knobs are fixed at one backset?
The Sure-Loc Durango knob adjusts between a 2-3/8 inch and 2-3/4 inch backset, so one part covers either door prep. Several alternatives are stated at a single backset: the Baldwin Estate 5000 Baltimore passage and privacy knobs are listed at 2-3/8 inch with a full lip strike, the Omnia 458/0 single dummy latchset at 2-3/8 inch, and the Falcon W101 and Sargent 8XG04 at 2-3/4 inch. The Kwikset 200P-CP passage knob ships with a round corner adjustable latch.
8) I need a classroom or storeroom function knob - does the Durango cover that?
No. The Sure-Loc Durango knob comes in Dummy, Entry, Entry/Deadbolt Combo, Passage, and Privacy only. For a classroom opening, the Dexter C2000 Series is a Grade 2 keyed classroom ball knob lock for doors 1-3/8 inch to 1-3/4 inch. For storeroom, the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with single cylinder and the Sargent 8XG04 is the Grade 1 heavy duty equivalent.
9) What is the Durango knob actually made of, and will it hold up in a rental?
The knob is a hollow, mushroom-shaped knob formed from brass on a tubular chassis. That is standard residential-duty construction, fine for apartments and homes. For a high-traffic opening where you want more, a Grade 2 cylindrical knob like the Dexter C2000 entry/office or the Corbin Russwin CK4410 passage is the step up in the same 1-3/8 to 1-3/4 inch door range.
10) Can I replace a Kwikset Polo knob with a Sure-Loc Durango?
On the keyway side, yes. The Durango uses the KW1 profile as standard, the same keyway family the Kwikset 400P-CP keyed entry knob uses, so existing KW1 keys stay in the same system. The Kwikset 400P-CP is also listed for 1-3/8 to 1-3/4 inch doors, matching the Durango's range, and both are bored tubular preps.
11) Does the Durango dummy knob need a bored hole in the door?
A dummy knob has no latch and no working spindle, so it does not use the latch bore in the door edge. It surface mounts as a fixed pull, typically on a closet door or the inactive leaf of a pair. If you need a knob that retracts a latch but does not lock, order the Passage function instead.
12) I only need a bedroom privacy knob, not a keyed set - what is a simpler option than the Durango?
The Sure-Loc Durango is offered in a Privacy function, but it is sold keyed alike in sets of four, which is more than a single bath door needs. For one non-keyed privacy opening, the Dexter C2000 Series privacy ball knob is a Grade 2 non-keyed lock 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 Pamex FTF Baron is a Grade 3 privacy knob lockset, also 1-3/8 inch to 1-3/4 inch.
13) Which knobs look like a substitute for the Durango dummy but will not actually work the same way?
The Sure-Loc Durango dummy is one of five functions in a tubular bored lockset family that also includes Entry, Entry/Deadbolt Combo, Passage, and Privacy. Some dummy knobs sold nearby are pairs rather than single trims: the Emtek Arts and Crafts Hammered Egg dummy and the Emtek Classic Brass Crystal Georgetown and Providence dummies are supplied as pairs, and Emtek Porcelain Knobs ship two knobs per set with a threaded rod. The Schlage A170 and BEST 6K-1DT are single dummy trims, both Grade 2. Confirm single versus pair before ordering.
14) I need a knob with an ANSI grade on the spec sheet - what compares to the Durango?
The Sure-Loc Durango is a residential tubular knobset offered in Dummy, Entry, Entry/Deadbolt Combo, Passage, and Privacy. When a submittal calls out a grade, the Callan Edgewood is a Grade 2 entrance knobset, the Bravura Albany and Lynchburg are Grade 2 passage knobsets, the Arrow MK01 is a Grade 2 passage cylindrical knob lock for 1-3/8 inch to 1-3/4 inch doors, and the Falcon W101 is a Grade 2 medium duty passage knob with a 2-3/4 inch backset and a fire rating.
15) If I do not want to issue keys at all, what replaces a keyed Durango entry knob?
The Sure-Loc Durango entry knob is a single cylinder keyed lock on a KW1 keyway. To avoid keys entirely, the Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function that fits doors 1 3/16 inch to 2 inch thick.
16) Is the Durango knob a substitute for exit device knob trim?
No. The Sure-Loc Durango is a tubular bored lockset that mounts in a standard residential bored-hole prep. Knob trim for an exit device is a different part: 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 for the ED-500 series.
17) What finish does the Sure-Loc Durango knob come in?
Two looks are offered. The knob is described in Satin Nickel, finish 15, and it is also sold in 15A Antique Nickel across all five functions (Dummy, Passage, Privacy, Entry and Entry/Deadbolt Combo). If you are matching hardware room to room, pick one and carry it through the whole unit.
18) What are the Sure-Loc Durango model numbers?
The Durango knob is catalogued under DU100, DU101, DU102 and DU107, with the number corresponding to the function you order (Dummy, Passage, Privacy, Entry or Entry/Deadbolt Combo). Quote the function along with the model when ordering so the right chassis ships.
19) What is a Satin Nickel passage or entry knob alternative to the Durango from another brand?
The Sure-Loc Durango knob is offered in Satin Nickel, finish 15, across its Passage and Entry functions. For a comparable look from another line, the Callan Roland is a Grade 2 entrance knob in US15 Satin Nickel. If the project is going brass instead, the Bravura Dallas with rectangle trim is a Grade 2 passage knobset in US4 Satin Brass.
20) What are decorative brass alternatives to the Durango knob for a higher-end residential door?
The Sure-Loc Durango uses a hollow, mushroom-shaped knob formed from brass. For solid brass decorative options, 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 with a 2-5/8 inch rose, and the Baldwin Estate 5077 Bethpage is a privacy knob with R027 rose. The Baldwin Estate 5011 Colonial is a passage knob with 5058 rose.
