Sure-Loc TL100 32D – Frequently Asked Questions

1) Will the Sure-Loc Tulip knob fit a 1-3/8 inch interior door, or is it only for 1-3/4?
Both. The Tulip knob covers doors 1-3/8 inch to 1-3/4 inch (35-45mm) thick, which is the standard residential range: 1-3/8 on older interior doors and 1-3/4 on entry and newer slabs. No spacer kit or different model needed between the two.
2) My doors are bored at 2-3/4 inch backset, not 2-3/8. Do I need a different Sure-Loc Tulip knob?
No. The Tulip latch is adjustable and sets to either 2-3/8 inch or 2-3/4 inch (60-70mm) on site, so one part covers both of the common bored-door preps. Useful when a building has a mix of older and newer door drilling and you want to stock one item.
3) What is the difference between the Dummy, Entry, Passage and Privacy versions of the Sure-Loc Tulip knob?
Four functions, four jobs. Entry (TL101) is the keyed single-cylinder version for exterior or lockable doors. Privacy (TL107) has a push-button or turn lock with no key, for bedrooms and baths. Passage (TL102) simply latches, no locking at all, for halls and closets. Dummy (TL100) is a fixed pull with no latch and no bore-through operation, used on closet doors and inactive leaves. Order the function per opening, not per building.
4) Are the Sure-Loc Tulip entry knobs keyed alike, and how many keys does a set cover?
They ship keyed alike in sets of 4, so one key runs all four locks. That is the practical reason to buy this one: a landlord or homeowner re-keying a house front, back, garage and side door ends up with a single key instead of four. If you need more than four openings on the same key, order in multiples of the set and confirm the keying instruction with your order.
5) Does the Sure-Loc Tulip knob use a Kwikset or Schlage keyway?
KW1 is the standard keyway on the Tulip knob, with SC1 available. KW1 is the Kwikset-profile blank, SC1 the Schlage profile, so if the rest of your property is already keyed on one of those two profiles you can keep the existing key system rather than starting a second one. Specify the keyway when you order the Entry function; the other three functions are not keyed.
6) I'm replacing a Kwikset Polo knob in a rental. Is the Sure-Loc Tulip a straight swap?
For a standard bored door it goes into the same prep. The Tulip covers 1-3/8 to 1-3/4 inch doors with a 2-3/8 or 2-3/4 inch adjustable backset, the same range the Kwikset 400P-CP keyed entry knob works in, and both use the KW1 Kwikset keyway, so existing keys and key systems carry over if you order the Tulip in KW1. The knob shape changes from ball to tulip; the door does not need rework.
7) The Sure-Loc Tulip is a residential knob. What should I use instead on a commercial opening that needs a Grade 1 lock?
The Sure-Loc Tulip knob is classified for residential use, so for a commercial opening specified Grade 1 you want a heavy duty cylindrical knob lock instead. The BEST 8K Series entrance knob lock is Grade 1 heavy duty with a single cylinder. For a keyed entrance/office function, the Corbin Russwin CK4851 is a Grade 1 cylindrical knob lock with a conventional cylinder and a 1-3/8 inch to 2 inch door thickness range. On the non-keyed side, the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core, fire rated, covering doors 1-3/8 inch to 2-1/4 inch.
8) What is the closest keyed entry alternative to the Sure-Loc Tulip knob if I need a Kwikset keyway?
The Sure-Loc Tulip entry knob (model TL101) is a single-cylinder tubular lock supplied with a KW1 keyway, with SC1 available. If you want a comparable keyed entry knob on the Kwikset keyway, the Cal-Royal BER00 is an entrance/office knob lock built with a Kwikset keyway and fits doors 1-3/8 inch to 1-3/4 inch, the same thickness range the Tulip covers. The Kwikset 400P-CP Polo keyed entry knob is another Kwikset-keyway option, rated Grade 3 and fitting 1-3/8 inch to 1-3/4 inch doors, and it ships with a round corner adjustable latch and round corner strike.
9) Is there a Grade 2 equivalent to the Sure-Loc Tulip knob that covers the same four functions?
The Sure-Loc Tulip is offered in dummy, entry, passage and privacy functions across models TL100, TL101, TL102 and TL107. The Dexter C2000 Series ball knob line covers the same span with a graded product: the C2000 entry/office, passage and privacy knob locks are each Grade 2 and fit doors 1-3/8 inch to 1-3/4 inch, matching the Tulip's door thickness range, and the series also adds a Grade 2 classroom function that the Tulip does not offer. For the dummy side of a Grade 2 set, the Schlage A170 single dummy trim is a Grade 2 heavy duty non-keyed knob covering 1-3/8 inch to 1-7/8 inch doors.
10) My doors are 2 inches thick. Which knob locks work where the Sure-Loc Tulip does not?
The Sure-Loc Tulip knob fits doors 1-3/8 inch to 1-3/4 inch, so a 2 inch door is outside its range. Deltana's knob line reaches further: the 3381 Egg knob entry, the 6171 Round knob entry and the 6112 St. Thomas privacy knob each cover 1-3/8 inch to 2 inch doors. Corbin Russwin's CK4310 Grade 1 passage/closet knob also covers 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 passage knobset goes to 2-1/4 inch. Note the Deltana 6901 Portland knob entry stops at 1-3/4 inch, the same as the Tulip.
11) Which knob products look like substitutes for the Sure-Loc Tulip entry knob but will not work as a complete lockset?
Several knob items in the same family are trim only, not a full bored lockset like the Sure-Loc Tulip. The Sargent 78-2875 is an outside knob only with B design, the Sargent 28C-KNOB is exit device trim with knob and rose for 1-3/4 inch doors, and the Imperial USA ED-BKL580 is knob trim in storeroom function from the ED-500 series - all of these dress an existing device rather than latch a door on their own. Dummy items are the other trap: the Sure-Loc TL100 dummy, the BEST 6K single dummy trim and the Schlage A170 single dummy trim have no latch at all and are surface mounted pulls. The Emtek porcelain knobs ship as two knobs per set with a threaded rod, again not a latching lockset.
12) Can I use the dummy version of the Sure-Loc Tulip knob on a double closet door?
Yes, that is what TL100 is for. A dummy is surface mounted trim with no latch and no turning mechanism, so it works on inactive leaves and closet doors that hold shut on a roller or magnetic catch. Order one per leaf. If you need a matched pair sold together, Emtek's Arts and Crafts Hammered Egg dummy and the Classic Brass Crystal Georgetown dummy ship as pairs.
13) For a multi-family turn, is the Sure-Loc Tulip knob a better choice than a Grade 2 cylindrical lock?
It depends on the door. Inside the unit, bedrooms, baths, closets and passage doors, the Tulip is a residential tubular lockset and the keyed-alike sets of 4 cut down key management across a building. For corridor and common-area doors that see constant traffic, step up to a Grade 2 cylindrical such as the Dexter C2000 entry/office knob or the Arrow MK01 passage knob, both rated for 1-3/8 to 1-3/4 inch doors. Mixing the two by opening type is normal practice.
14) What is a simpler Grade 3 alternative to the Sure-Loc Tulip knob for apartment interior doors?
The Pamex FTF Baron knob lockset covers the same interior mix in Grade 3 with separate entrance/office, privacy and passage versions, all fitting doors 1-3/8 inch to 1-3/4 inch, the same range the Sure-Loc Tulip fits. Cal-Royal's Barrington line is another Grade 3 route, with the BER20 privacy knob and BER00 entrance/office knob both covering 1-3/8 inch to 1-3/4 inch doors. The difference to plan around is keying: the Tulip is supplied keyed alike in sets of four, so if you want one key across several units you would need to specify keying separately on the Grade 3 options.
15) I need a storeroom function knob. Does the Sure-Loc Tulip cover that, and if not what does?
The Sure-Loc Tulip knob is offered in dummy, entry, passage and privacy only, so a storeroom opening needs a different lock. The Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, and the Sargent 8XG04 is the Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset. For a classroom function instead, the Dexter C2000 Series classroom ball knob lock is Grade 2, keyed, and fits doors 1-3/8 inch to 1-3/4 inch.
16) If I only need a passage knob and not a keyed set, what can I use in place of the Sure-Loc Tulip?
The Sure-Loc Tulip passage model is TL102, and there are plenty of dedicated non-keyed passage knobs if you do not need the keyed entry versions. The Arrow MK01 and RK01 are both Grade 2 non-keyed passage/hall/closet cylindrical knob locks fitting 1-3/8 inch to 1-3/4 inch doors, the RK01 using a ball knob. Corbin Russwin's CK4410 is a Grade 2 non-keyed passage/closet lock over the same thickness range. In residential styling, the Kwikset 200P Polo passage knob ships with a 6AL latch and round corner strike, and the 200P-CP version comes with a round corner adjustable latch. Bravura offers Grade 2 passage knobsets in the Albany, Lynchburg and Dallas designs.
17) I want to key several doors alike like the Sure-Loc Tulip set. What other entry knobs are options?
The Sure-Loc Tulip entry knob is a single cylinder tubular lock supplied keyed alike in sets of four on a KW1 keyway, with SC1 available, which is what makes it convenient across several doors in one building. If you would rather specify keying yourself, comparable keyed entry knobs include the Master Lock BC Series BC01 Grade 3 biscuit knob keyed entry, the Callan Edgewood Grade 2 entrance knobset, the Callan Canova and Santo Grade 3 entrance knobsets, and Delaney's Grade 3 entrance knobsets in the Belton, Galway and Olivia designs. Confirm the keyway on whichever you pick before combining it with Tulip cylinders on the same key.
18) Is there a keyless option instead of the keyed Sure-Loc Tulip entry knob?
The Sure-Loc Tulip entry knob is a keyed single cylinder tubular lock on a KW1 keyway. If you want to eliminate 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, a wider range than the Tulip's 1-3/8 inch to 1-3/4 inch. It is mechanical rather than electronic, so there is no wiring or batteries to plan for, but users enter a combination rather than carrying the keyed-alike keys the Tulip set provides.
19) What are the dummy knob alternatives to the Sure-Loc Tulip TL100?
The Sure-Loc Tulip dummy is model TL100 and comes in polished brass and satin stainless. Comparable dummy trims include the Cal-Royal BA40 Barrington dummy knob cylindrical lock for 1-3/8 inch to 1-3/4 inch doors, the Bravura Biloxi Grade 2 dummy knobset with round trim, the BEST 6K Series Grade 2 medium duty single dummy trim, and the Schlage A170 Grade 2 heavy duty single dummy trim. For a decorative dummy, Omnia offers the 434/0 and 442/00 solid brass single dummies and Emtek the Arts and Crafts hammered egg dummy pair.
20) What is the Sure-Loc Tulip knob made of?
The knob itself is formed brass and hollow rather than solid cast. That keeps the weight down on a standard residential bore. If you want a solid brass knob for a higher-end interior, Omnia's 434/PA passage latchset and 458/0 single dummy are solid brass construction, and Baldwin's Estate 5011 Colonial passage knob is another traditional option.
