Schlage Residential J170 CNA 620 – Frequently Asked Questions

1) What does a Schlage J170 half dummy knob actually do - does it latch or lock?
No latch, no lock, no moving parts. The J170 Corona knob is inactive trim for one side of a door: it mounts as a fixed pull or as matching trim so a door reads the same as the locking openings around it. The knob does not turn and there is no bolt, so nothing holds the door shut. If the door needs to stay closed you want a passage or privacy set instead.
2) Will the Schlage J170 fit a 1-3/8 inch interior door?
Yes. The J170 covers 1-3/8 to 1-3/4 inch doors, which spans the common older interior thickness and the standard 1-3/4 inch door. That range is the same one the Corona knob is built to across the J Series.
3) Do I need to drill a backset for a half dummy knob, and does 2-3/8 or 2-3/4 matter?
Backset is not a factor on the half dummy. There is no latch in a J170, so it mounts to the door face with no cross-bore for a latch and no edge prep. The 2-3/8 and 2-3/4 dual backset latch spec on the J Series applies to the latching functions, not to this dummy trim. If you are matching a J Series knob that does latch, that one takes either backset with the same latch.
4) Is the Schlage J170 dummy knob fire rated for a labeled door?
Fire rating on the J Series is an option limited to the J10 and J54 functions. The J170 dummy is not one of those, so it should not be specified where a labeled opening needs rated hardware. If you need a rated non-keyed cylindrical set, the Falcon K101 passage lock and the Corbin Russwin CL3110 passage both carry a fire rating in our records.
5) I need dummy trim on both sides of a pair of doors - is the J170 the right part?
No. The Schlage J170 Corona is a half dummy, supplying inactive trim for one side of the door only. For matching trim on both faces, a dummy pair is the correct order: Emtek sells the Arts and Crafts Lever dummy as a pair, the Hammered Lever dummy as a pair, and the Classic Brass Cortina Lever dummy as a pair. Use those where both sides of the leaf need a pull; use the J170 where only one face is trimmed.
6) What is the closest equivalent to the Schlage J170 Corona half dummy if the door needs a lever instead of a knob?
The Schlage J170 Corona is a knob-style dummy with inactive trim on one side of the door, so a lever-shaped equivalent has to come from a different family. The BEST 7KC Series 1DT is a Grade 2 non-keyed single dummy trim cylindrical lever lock, matching both the dummy function and the Grade 2 rating with a lever pull instead of a knob. Accentra's 5400 Series 455LN Augusta is also a single dummy cylindrical lever lock, rated Grade 1. Both give a fixed pull with no latch, the same way the J170 does.
7) What should I use instead of a J170 half dummy if the door actually needs to latch closed?
The J170 Corona is a dummy - inactive trim used as a door pull, with no latching function at all. For a closet or hall door that has to latch and be opened by turning the handle, a passage set is the right part: the Falcon B101 is a Grade 2 non-handed cylindrical passage lever lock, and the Accentra 5301LN Augusta is a Grade 2 cylindrical passage/closet lever. If the opening is on a fire-rated or heavier-use door, the Falcon K101 is a Grade 1 fire-rated passage lock covering 1-3/8 inch to 2-1/4 inch doors.
8) Is a Baldwin 5103 half dummy a drop-in alternative to a Schlage J170 half dummy?
They serve the same purpose but order differently. The Schlage J170 Corona is non-handed, so one part number covers both left and right hand doors. The Baldwin Estate 5103 half dummy is handed and sold as two separate items - 5103 Left Hand Half Dummy Lever with 5048 Rose and 5103 Right Hand Half Dummy Lever with 5048 Rose. If you go the Baldwin route on a multi-door job, the hand of each opening has to be confirmed before the order goes in; with the J170 it does not.
9) The bedroom door needs a lock for privacy - can a J170 do that?
No. The Schlage J170 Corona is non-keyed and dummy function, with no latch and no locking mechanism of any kind. For a bed or bath door, a privacy set is what to specify: the Kwikset 300BRNL RDT Breton is a Grade 3 privacy lever set for 1-3/8 inch to 1-3/4 inch doors, matching the J170's door thickness range, and the Baldwin Estate 5103 Privacy Lever with 5048 Rose is the privacy version of that trim. The Arrow MK02-TA is a fire-rated privacy cylindrical knob lock for 1-3/4 inch to 2 inch doors.
10) Which passage knob or lever fits the same 1-3/8 inch to 1-3/4 inch doors the J170 fits?
The Schlage J170 Corona covers 1-3/8 inch to 1-3/4 inch doors. Among working sets in the same range, the Kwikset 200BRNL RDT Breton passage lever set is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AG05 Grade 2 storeroom leverset and AUS00 Grade 3 entrance/office lever both cover 1-3/8 inch to 1-3/4 inch. Note that the Arrow GL01 Grade 2 passage lock and the Corbin Russwin CL3110 Grade 1 passage lock are specified for 1-3/4 inch to 2 inch doors, so they do not reach down to a 1-3/8 inch leaf.
11) Does the J170 half dummy need to be ordered left hand or right hand?
Non-handed. One part number works on a left or right hand door with no reversing, which is a difference worth knowing if you have priced Baldwin Estate half dummies, where the 5103 is ordered as a specific left hand or right hand part.
12) What finishes does the Schlage J170 Corona knob come in?
Eight finishes, all on the Corona knob design: 605 bright brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 622 matte black, 625 bright chrome, 630 satin stainless steel and 716 aged bronze. That spread lets you match a dummy to existing brass or nickel trim in a unit without changing the rest of the openings.
13) Is a Schlage J Series knob strong enough for apartment turnover work, or do I need a commercial grade lock?
The J170 is residential hardware carrying a Grade 2 rating, which is fine for apartment and condo interior trim. For a corridor or a leased commercial space where a dummy trim gets pushed on all day, the Grade 1 dummy options are the BEST 9K Series 1DT single dummy trim and the Accentra 455LN Augusta, both heavy duty lever trim rather than a knob. BEST also lists the 7KC Series 1DT as a medium duty Grade 2 dummy.
14) Can the J170 be keyed to match the rest of my Schlage locks?
It cannot be keyed at all. The J170 is a non-keyed dummy with no cylinder in it, so there is nothing to key alike or add to a master system. Key the latching openings in the same J Series and use the J170 purely for the fixed trim.
15) I need a knob, not a lever, for a closet or pantry door that has to stay shut - what should I order instead of a dummy?
A dummy will not hold a closet door. For a knob that latches without a key, look at a passage function set: Arrow's MK and RL Series knobs cover Tudor and ball knob styles, and the Arrow HK11 ball knob entrance lock takes the same 1-3/8 to 1-3/4 inch door range as the J170. Keep the J170 for the inactive leaf of a pair or for a false front where you only want the pull.
16) What is the difference between the Schlage J170 dummy and the BEST 9K 1DT dummy trim?
Both are non-keyed single dummy trim with no latching function. The Schlage J170 Corona is a Grade 2 knob for residential openings covering 1-3/8 inch to 1-3/4 inch doors. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever lock. The 9K is the heavier-duty lever version; the J170 is the knob version at Grade 2. Choose on whether the opening wants a knob or a lever and on the duty level the facility specifies.
17) Is there a Grade 2 dummy lever that matches other levers already installed in the building?
Yes. The Callan Bentley is a Grade 2 dummy lever from the Bentley series, so a property standardizing on a lever look can carry the dummy in the same grade as the working sets. The BEST 7KC Series 1DT is another Grade 2 non-keyed single dummy trim option, in medium duty. Both fill the same role as the Schlage J170 Corona - a fixed pull with no latch - in lever form rather than knob form.
18) Does a non-keyed passage set work as a substitute for a J170 half dummy?
It looks similar on the door but behaves differently. The Schlage J170 Corona is dummy function - the knob is fixed and there is no latch behind it. A passage set such as the Accentra 4601LN Grade 2 passage cylindrical lever or the Bravura Atlanta Grade 2 passage leverset is also non-keyed, but the handle turns and throws a latch, which means the door has to be bored and the frame prepped for a strike. If the opening has no latch prep and the trim is only there to pull the door, the passage set is not a substitute.
19) For an apartment turn, what pairs with a J170 dummy on the entry door itself?
The J170 Corona is Grade 2 residential trim with no key function, so it handles the inactive side only and the entry hardware has to come from elsewhere. Hager's 2525 is a Grade 2 commercial cylindrical entry lock covering 1-3/8 inch to 2 inch doors, and the Falcon B511CP6D is a Grade 2 medium duty entry/office cylindrical lever. Cal-Royal's AG00 entrance lever uses a 6-pin Schlage C keyway with a 2-3/8 inch backset, which keeps a unit on Schlage C keying across the fleet.
20) What tools and door prep does installing a Schlage J170 dummy knob take?
A screwdriver and a face bore. Because there is no latch and no strike involved, the install is trim to door face only, which is why it is the fastest thing in the J Series to hang. Nothing gets routed into the door edge and no strike is mortised into the frame.
