Emtek 6143-FB – Frequently Asked Questions
1) Will the Emtek 6143 STRETTO passage set fit a narrow stile or narrow-rail door?
That's exactly what the 6143 STRETTO is built for. The trim plate measures 1-1/2" x 11-1/8", and it uses a narrow 1-1/4" door prep with 3-3/8" center-to-center hole spacing rather than the usual wide rosette layout. If your door rail or stile is too slim to take a standard 2-1/8" round rosette, this narrow trim plate is the way to get a knob or lever on it.
2) What backset does the Emtek 6143 narrow trim lockset use, and can I use it on a 2-3/4 inch prep?
Both standard backsets are covered. The latch is adjustable for a 2-3/8" or 2-3/4" backset, and 2-3/8" is what ships unless you call out 2-3/4" on the order. Measure from the door edge to the center of the cross bore to confirm which one your existing prep uses.
3) Does the Emtek 6143 passage set work on a 1-3/8 inch interior door?
Yes. The 6143 STRETTO passage set covers doors from 1-3/8" up to 1-3/4", which takes in both the older 1-3/8" interior doors and standard 1-3/4" stock. The cross bore is 2-1/8", the same bore a conventional bored lockset uses.
4) Is the Emtek 6143 a locking set, and where should I use it?
It's a passage set, non-keyed, so there is no locking of any kind. The knob or lever retracts the latch from both sides at all times. Use it on hallway, closet, and pantry doors. For a bathroom or bedroom you want a privacy set instead, and for an entry you want a keyed function.
5) What do I have to specify when ordering the Emtek 6143 STRETTO set?
Four choices are required. Finish, which is Flat Black (FB) or Medium Bronze (MB). The knob or lever, chosen from sixteen brass and porcelain designs including Medici, Napoli, Octagon and Padua levers, Octagon, Parma, Petal, Diamond, Georgetown, Old Town, Bristol, Hampton, Lowell and Windsor knobs, and Ebony or Ice White porcelain knobs. Handing, right or left. And backset, 2-3/8" or 2-3/4".
6) Do I need to know the handing for an Emtek 6143 passage lockset?
If you're putting a lever on it, yes. Handing is called out for leversets so the lever hangs the right way on your door. Stand on the outside of the door: hinges on the right is right hand, hinges on the left is left hand. Knob versions are symmetrical in use, but the order still asks you to pick a hand.
7) Does the Emtek 6143 come with a latch and strike, or do I order those separately?
Complete set. The latch and strike plate are in the box, and the latch is a 28 degree unit. The latch faceplate is available with round or square corners, so you can match whatever is already mortised into the door edge.
8) Can I mix Emtek 6143 narrow trim sets with round rosette sets on the same floor?
You can, as long as you're only matching appearance and not prep. The 6143 uses a narrow 1-1/4" prep with 3-3/8" hole spacing, which is not the same layout as a standard rosette set, so it is not a drop-in swap for a round-rosette door without new boring. The knob and lever designs and the Tuscany Bronze finishes carry across, so the handles can match even where the trim shape differs.
9) Is the Emtek 6143 STRETTO set suitable for a commercial corridor or apartment building?
It is classified residential. The 6143 is a tubular passage set aimed at homes and residential interiors. For a commercial corridor or a high-traffic multi-family opening, you want a cylindrical or mortise lock built for that duty rather than this narrow trim residential set.
10) What is the Emtek 6143 made of, and how does the Tuscany finish look?
Brass construction with a bronze substrate for the Tuscany line, offered in Flat Black and Medium Bronze. Tuscany Bronze is a solid-bronze design family, so the Medium Bronze in particular is a living finish look that reads warm and darker in relief.
