Schlage Residential J170 BYR 605 – Frequently Asked Questions

1) What does a half dummy knob like the Schlage J170 Byron actually do on the door?
It's inactive trim for one side of the door only. The Byron knob doesn't turn or retract anything, and there's no latch behind it, so it works as a pull or as matching trim beside doors that do have working hardware. Typical uses are closet and pantry doors, French door pairs where one leaf is fixed, and any opening held by a ball catch or roller catch.
2) Do I have to specify handing on a half dummy the way some brands require?
The Schlage J170 Byron half dummy is non-handed and works on left or right hand doors without modification. Some half dummies are handed and must be ordered by side: the Baldwin Estate 5103 half dummy lever with 5048 rose is supplied as a distinct left hand part and a distinct right hand part. If you are stocking one part number for mixed openings, the non-handed J170 avoids the split.
3) I need dummy trim on both sides of a double door, not just one side. What should I order instead of the J170?
The Schlage J170 Byron is a half dummy, inactive trim for one side of the door only. For trim on both faces, Emtek supplies dummy pairs: the Arts and Crafts lever dummy pair, the Hammered lever dummy pair, and the Classic Brass Cortina lever dummy pair are all sold as dummy pairs. Use those where each leaf face needs a pull and the J170 where only one side is trimmed.
4) The door actually needs to latch closed. What replaces a J170 dummy on that opening?
A dummy such as the Schlage J170 Byron has no latch at all, it is inactive trim used as a door pull or matching trim. For a door that must latch without keying, passage function is the substitute: the Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, matching the J170 door range, the Falcon B101 is a Grade 2 non-handed cylindrical passage lever, and the Dexter C1000 passage lever is Grade 1 for 1-3/8 inch to 1-3/4 inch doors.
5) What is the closest equivalent to the Schlage J170 Byron half dummy if I need a Grade 1 dummy instead of Grade 2?
The Schlage J170 Byron is a non-handed Grade 2 cylindrical dummy with inactive trim on one side of the door. For a Grade 1 dummy in the same single-dummy configuration, the BEST 9K Series 1DT is a heavy duty Grade 1 non-keyed single dummy trim, and the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lock. Both of those carry levers rather than a knob, so if the surrounding doors are knob-trimmed the J170 keeps the styling consistent.
6) My doors are 2 inches thick. Will the J170 half dummy work, or do I need something else?
The Schlage J170 Byron half dummy covers 1-3/8 inch to 1-3/4 inch doors, so a 2 inch door is outside that range. Sets rated to 2 inches include the Hager 2510 Grade 2 passage lever at 1-3/8 inch to 2 inch, the Dexter C1000 asylum function at 1-3/8 inch to 2 inch, and the Arrow GL01 Grade 2 Sierra lever passage set at 1-3/4 inch to 2 inch. Those are latching functions rather than dummy trim, so confirm the function the opening needs.
7) Is the J170 keyed, and can it be keyed alike with my other Schlage locks?
No. The J170 is a non-keyed dummy, with no cylinder and no keyway in it at all. If you want the same look on a door that needs to key into a system, use a keyed J Series function and carry the J170 only on the inactive or pull side.
8) Does a half dummy knob need a latch bore, or can I put it on an undrilled door?
Only the cross bore is needed. Because the J170 is inactive trim with no latch mechanism, nothing runs into the door edge, so there's no edge bore or strike prep. On an undrilled door you're drilling a single face bore to mount it; if you're swapping out an existing knob, the hole is already there.
9) I am specifying inactive trim for a heavy traffic multi-family corridor. Should I step up from the J170?
The Schlage J170 Byron half dummy is a Grade 2 residential dummy. Where the traffic argues for heavier construction, the BEST 9K Series 1DT single dummy trim is Grade 1 heavy duty and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy. Both are lever trim; the J170 is a Byron knob, so the choice also decides the handle style on that face.
10) Is there another Grade 2 dummy lever I can use alongside Schlage J170 knobs on the same project?
Two Grade 2 dummy options sit in the same grade as the Schlage J170 Byron half dummy: the BEST 7KC Series single dummy trim, a medium duty Grade 2 non-keyed dummy, and the Callan Bentley Grade 2 dummy lever. Both are lever trim, while the J170 is a Byron knob, so pick by the handle style already on the doors rather than by grade.
11) The bath door needs privacy, not dummy trim. What is the right part?
The Schlage J170 Byron half dummy is non-keyed inactive trim with no locking mechanism, so it will not serve a bath or bedroom. For privacy function, the Kwikset 300BRNL Breton privacy lever is Grade 3 and covers 1-3/8 inch to 1-3/4 inch doors like the J170, the Hager 2540 is a Grade 2 privacy set with a Withnell lever for 1-3/8 inch to 2 inch doors, and the Baldwin Estate 5103 privacy lever with 5048 rose is the option if you are matching Baldwin trim elsewhere.
12) Which of these dummy options are not actually interchangeable with a Schlage J170?
Several parts look adjacent but do not substitute for the Schlage J170 Byron non-keyed knob dummy. The Emtek dummy sets are supplied as pairs rather than single-side trim. The Baldwin Estate 5103 half dummy is handed, sold as separate left hand and right hand parts, while the J170 is non-handed. And the Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, a cylinder accessory rather than a trim set, so it has no bearing on a dummy opening.
13) Is the Schlage J170 an electronic or keypad lock?
No, it's a purely mechanical piece of trim with no electronics, no batteries and no wiring. If you're after keypad access on the opening, that's a different product class entirely, such as the Emtek Classic keypad leverset or the Delaney LP250 electronic keypad leverlock.
