Sure-Loc DU100 15 – Frequently Asked Questions

1) Do I have to specify left or right hand when ordering a Sure-Loc Durango knobset?
No handing to specify. Sure-Loc bored locks are reversible, so the same knobset works on a left or right hand door and you set it at install rather than at the order desk. Order by function and finish only.
2) What is the difference between the Entry and the Entry Deadbolt Combo version of the Durango knob?
Entry is the keyed knob on its own. Entry Deadbolt Combo pairs that keyed knob with a matching deadbolt, so you get the second bore covered and the two cylinders operating on one key. On an exterior door where you want a deadbolt anyway, the combo saves you buying and keying the deadbolt separately. Both are offered in Vintage Bronze, Satin Nickel, Polished Chrome and Flat Black.
3) Can I get several Sure-Loc Durango entry knobs keyed alike for one property?
Yes, in fours. The Durango Entry and Entry Deadbolt Combo functions come keyed alike in sets of four, so a landlord or property manager doing a unit turn can run one key across the front, back and side doors. Sets of four are the unit, so plan the opening count in multiples if you want the whole building consistent.
4) Is the Sure-Loc Durango knob rated for a commercial building or an apartment corridor?
It is a residential-duty knobset, built for houses, condo interiors and light rental use. For a commercial corridor, a school or anywhere with heavy traffic, step up to a Grade 1 cylindrical knob like the Falcon X101 or the BEST 8K Series, or a Grade 2 such as the Dexter C2000 entry knob. Those are graded and duty-rated for that traffic; the Durango is not.
5) Will a Sure-Loc Durango knob go straight into the hole left by an old knob I am replacing?
On a standard residential prep, yes. The Durango is a tubular cylindrical knobset with an adjustable 2-3/8 to 2-3/4 inch backset and it fits standard residential door preparation, which is the bore pattern the vast majority of house doors already have. No new boring if the existing knob was a normal residential tubular unit. What it will not do is fill a mortise pocket or a commercial prep cut for a heavy Grade 1 lock.
6) Will a Sure-Loc Durango round knob work on a 2 inch thick door?
The Durango round knob fits doors 1-3/8 inch to 1-3/4 inch (35-45mm) thick, so for a thicker slab choose a knob rated past that. The Deltana 6171 Round Knob in entry function fits doors 1-3/8 inch to 2 inch thick and keeps the round knob profile; the Deltana 6112 St. Thomas covers the same 1-3/8 inch to 2 inch range in privacy. On the commercial side, the Corbin Russwin CK4310 Grade 1 passage cylindrical lock also fits 1-3/8 inch to 2 inch doors, and the Falcon X101 passage knobset goes to 2-1/4 inch.
7) What is the closest equivalent to a Sure-Loc Durango round knob in privacy function?
For a bed or bath opening, the Dexter C2000 privacy cylindrical ball knob lock is a close peer - it is a Grade 2 privacy/bed/bath knob that fits doors 1-3/8 inch to 1-3/4 inch thick, the same thickness range the Durango round knob covers. The Pamex FTF Baron knob lockset in privacy function is a Grade 3 privacy/bed/bath knob over the same 1-3/8 inch to 1-3/4 inch door range. Both are round-rose tubular knobs, so the door prep carries over from a Durango privacy knob.
8) What keyed entry knob can I use in place of a Sure-Loc Durango entry knob?
The Kwikset 400P-CP Polo keyed entry knob is the nearest match - a Grade 3 entrance knob for doors 1-3/8 inch to 1-3/4 inch thick, shipping with a round corner adjustable latch and round corner strike, which is the same residential prep the Durango entry knob uses over its 1-3/8 inch to 1-3/4 inch door range. If you want a Grade 2 keyed knob instead, the Dexter C2000 entry/office cylindrical ball knob lock covers the same door thickness range. The Cal-Royal BER00 entrance/office knob is a Grade 3 option with a Kwikset keyway, which matters if you are keying into existing Kwikset-keyed cylinders on the property.
9) The Sure-Loc Durango round knob is residential - what knob should I specify for a commercial corridor instead?
The Durango round knob is a residential tubular knobset, so for commercial traffic step up to a Grade 1 cylindrical lock. The BEST 8K Series single cylinder knob lock is a Grade 1 heavy duty entrance knob, and the Corbin Russwin CK4851 is a Grade 1 entrance/office cylindrical lock with a conventional cylinder that fits doors 1-3/8 inch to 2 inch thick. For non-keyed corridor and closet openings, the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset that is fire rated and fits doors 1-3/8 inch to 2-1/4 inch thick.
10) Is a Sargent 28C-KNOB or a Sargent 78-2875 a substitute for a Sure-Loc Durango round knob?
No. The Durango round knob is a complete tubular knobset that fits standard residential bored door prep with an adjustable 2-3/8 inch to 2-3/4 inch backset. The Sargent 28C-KNOB is exit device trim with a knob and rose for 1-3/4 inch doors, and the Sargent 78-2875 is an outside knob only in the 7800 Series - both are trim for an exit device, so they mount to a panic hardware chassis rather than into a bored residential door. The Imperial USA ED-BKL580 knob trim is likewise exit device trim in the ED-500 Series. If you want a knob that goes into a bored 2-3/8 inch backset door, stay with a knobset such as the Dexter C2000 entry/office ball knob lock.
11) I need a knob that locks a storeroom door behind itself - does the Sure-Loc Durango cover that?
The Durango round knob is offered in Dummy, Passage, Privacy, Entry and Entry Deadbolt Combo, so storeroom is not among its functions. For a storeroom opening, the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset. For a school or classroom door, the Dexter C2000 classroom ball knob lock is Grade 2 and fits doors 1-3/8 inch to 1-3/4 inch thick.
12) Which knob do I use on a fire rated door instead of a Sure-Loc Durango round knob?
Choose a knob carrying a fire rating. The Falcon W101 is a Grade 2 medium duty cylindrical knob lock in passage/closet latch 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, also fire rated, fitting doors 1-3/8 inch to 2-1/4 inch thick. Note the W101 comes at a fixed 2-3/4 inch backset rather than the adjustable 2-3/8 inch to 2-3/4 inch backset the Durango uses, so confirm the bore centerline on the opening before ordering.
13) Which Durango function do I use on a bedroom or bathroom door versus a closet?
Privacy for bed and bath, passage for closets and halls. The privacy function locks from inside for a bathroom or bedroom; passage latches only, no lock, which is what a closet or a hall door wants. The Durango also comes as a dummy for a false or inactive leaf with no latch at all, so a pantry or a double-door inactive side gets matching trim without a bore.
14) I need matching knobs across a whole house in one finish. Does the Durango cover every door type?
It does. All five functions, Dummy, Passage, Privacy, Entry and Entry Deadbolt Combo, are offered in each of the four finishes, so a single finish carries the closets, the bedrooms, the front door and any false leaf. That is the reason to pick one line for a full turn rather than mixing brands per door.
15) What is a Grade 3 or Grade 2 alternative to the Sure-Loc Durango if I want a stated ANSI grade?
The Durango is a residential knobset. If your spec sheet calls for a graded lock, the Pamex FTF Baron in entrance, privacy or passage is Grade 3 and fits 1-3/8 to 1-3/4 inch doors, the same thickness range. The Kwikset 400P-CP keyed entry knob is Grade 3 over that same range. For Grade 2 on a residential-thickness door, the Dexter C2000 series covers entry, privacy and passage, all 1-3/8 to 1-3/4 inches.
16) I only need trim on an inactive door leaf. Is there a dummy version of the Durango, and what does it do?
There is, in all four finishes. The dummy Durango is a surface-mounted knob with no latch and no moving mechanism, used as a pull on a false door, an inactive leaf of a pair or a closet door held by a catch. It gives you the same mushroom knob look as the working doors. If you need a matched dummy from another line, the Schlage A170 single dummy trim and the BEST 6K single dummy are the graded equivalents.
17) I only need a non-latching pull on a closet door - what is a simpler option than a Sure-Loc Durango dummy knob?
The Durango round knob is offered in a Dummy function for exactly that. Equivalent single dummy trims include the Schlage A170 single dummy trim, a Grade 2 non-keyed knob for doors 1-3/8 inch to 1-7/8 inch thick, the BEST 6K Series single dummy trim, a Grade 2 medium duty dummy knob, and the Cal-Royal BA40 Barrington dummy knob for doors 1-3/8 inch to 1-3/4 inch thick. All three mount as trim only with no latch to bore for. If the opening takes a double door and you need a knob on each leaf, the Emtek Arts and Crafts Hammered Egg dummy ships as a pair.
18) What passage knob substitutes for a Sure-Loc Durango round knob on a hall or closet door?
For passage openings, peers with the same 1-3/8 inch to 1-3/4 inch door thickness range the Durango covers include the Arrow MK01 and Arrow RK01, both Grade 2 non-keyed passage/hall/closet cylindrical knob locks, the Dexter C2000 passage ball knob lock in Grade 2, and the Pamex FTF Baron passage knob in Grade 3. The Bravura Albany and Bravura Lynchburg round trim passage knobsets are Grade 2 and carry a round rose, which keeps the trim shape consistent if the rest of the doors are wearing a round-rose knob.
19) I do not want to hand out keys on a rental unit - is there a knob alternative to a Sure-Loc Durango entry?
Yes. 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, so tenants or crews enter on a code rather than a cut key. That is a different access method from the Durango Entry and Entry Deadbolt Combo functions, whose keyed cylinders come keyed alike in sets of four when you are standardizing several doors to one key.
20) Does a Baldwin Estate knob replace a Sure-Loc Durango round knob one for one?
Not one for one on backset. The Durango round knob takes an adjustable 2-3/8 inch to 2-3/4 inch backset, so it drops into either common bore centerline. The Baldwin Estate 5000 Baltimore knob is preconfigured at a 2-3/8 inch backset with a full lip strike in both passage and privacy, so it suits a 2-3/8 inch bore only. The Baldwin Estate 5011 Colonial is a passage knob with a 5058 rose, and the Baldwin Estate 5077 Bethpage is a privacy knob with an R027 rose - check the rose diameter against the wear ring left by the Durango before swapping on a finished door.
21) What is the difference between a Sure-Loc Durango round knob and a Kwikset Polo knob?
Both are residential tubular knobs with a round profile. The Durango round knob is a hollow, mushroom-shaped formed brass knob with an adjustable 2-3/8 inch to 2-3/4 inch backset, sold by function so one part number covers Dummy, Passage, Privacy, Entry or Entry Deadbolt Combo. The Kwikset 200P Polo passage knob ships with a 6AL latch and RCS round corner strike, while the 200P-CP pairs a round corner adjustable latch with a round corner strike; the keyed 400P Polo entry comes with the 6AL latch and RCS strike, and the 400P-CP is Grade 3 for doors 1-3/8 inch to 1-3/4 inch thick. The practical difference on a job is the latch and strike shipped in the box - confirm the existing mortise in the jamb is round corner before ordering.
22) Which entry knobs are comparable to a Sure-Loc Durango for a multi-unit turnover package?
Working from the Durango round knob's Entry function on 1-3/8 inch to 1-3/4 inch doors, the closest entry-function peers are the Callan Canova and Callan Santo in Grade 3, the Callan Edgewood in Grade 2, the Delaney Brookhaven entry knobset, and the Master Lock BC Series BC01 keyed entry biscuit knob in Grade 3. The Deltana 3381 Egg Knob and Deltana 6901 Portland Knob are also entry function, the 3381 for doors 1-3/8 inch to 2 inch and the 6901 for 1-3/8 inch to 1-3/4 inch. Any of these will bore the same residential opening; the choice comes down to grade and knob shape across the fleet.
23) What is the Durango knob actually made of, and will the finish hold up on an exterior door?
Formed brass, hollow, in a mushroom-shaped knob. Brass substrate takes plated and coated finishes well, which is what you get in Vintage Bronze, Satin Nickel, Polished Chrome and Flat Black. Note it is a hollow formed knob rather than a solid casting, so it is lighter in the hand than something like the Omnia 434 series, which is solid brass.
24) Is the Sure-Loc Durango a keypad or smart lock?
No, it is fully mechanical, no electronics, no batteries, no keypad. Keying is by cylinder key on the Entry and Entry Deadbolt Combo. If you want keyless on a residential-thickness door, the Lockey 3830 is a mechanical combination knob lock with an auto-locking passage function, fitting doors 1-3/16 to 2 inches.
25) What entry knob matches a satin nickel Sure-Loc Durango on the rest of the doors?
The Durango round knob comes in 15 - Satin Nickel across all five functions, including Entry. If you need another satin nickel entry knob alongside it, the Callan Roland is a Grade 2 entrance knobset in US15 Satin Nickel. Other Grade 2 and Grade 3 entrance knobsets to pair with it include the Callan Edgewood in Grade 2 and the Delaney Belton, Galway and Olivia in Grade 3 - confirm the finish code on those before committing, since satin nickel is normally coded US15.
26) Are there other round trim knobsets like the Sure-Loc Durango, or do I have to take a rectangular rose?
Round trim is well covered. The Durango round knob is a round knob on residential bored prep. Among peers, the Bravura Albany and Bravura Lynchburg are Grade 2 round trim passage knobsets and the Bravura Biloxi is a Grade 2 round trim dummy knobset. The Deltana 6171 Round Knob is an entry knob fitting doors 1-3/8 inch to 2 inch thick. If you specifically want rectangular trim, the Bravura Dallas is a Grade 2 passage knobset with rectangle trim in US4 Satin Brass.
