Emtek 4143-FB – Frequently Asked Questions

1) Will the Emtek 4143 STRETTO narrow trim lockset fit a narrow stile door or a door with a narrow rail?
That is what the 4143 is built for. The arched STRETTO plate measures 1-1/2" x 11" and the door prep is a narrow 1-1/4" bore with 3-3/8" center-to-center hole spacing, so it works where a standard 2-1/8" cross bore would blow out the stile. Note the spec sheet also lists a 2-1/8" cross bore for the tubular latch prep, so read the prep template before boring.
2) What backset does the Emtek 4143 passage set come with, and can I use it on a 2-3/4 inch backset door?
Both backsets are covered. The latch is adjustable for 2-3/8" or 2-3/4", and backset is a required selection when you order. Standard is 2-3/8"; specify 2-3/4" if your existing bore is set back further. Those are the two common residential backsets, so an existing prep will almost always match one of them.
3) Does the Emtek 4143 lock, or is it just a passage set?
Passage only. The 4143 is non-keyed with no cylinder and no privacy button, so the knob or lever simply retracts the latch and the door stays closed against the strike. Use it on hallways, closets, and pantry doors. For a bedroom or bath you need a privacy function instead, and for an exterior door a keyed set.
4) Do I have to specify handing on the Emtek 4143 STRETTO set?
Yes, handing is a required selection, right hand or left hand. Emtek calls for handing on leversets because the lever has to swing down toward the latch side. Stand outside the door: if the hinges are on your right it is right hand. Pick the knob or lever style and the handing together, since the trim plate ships assembled to that hand.
5) What comes in the box with the Emtek 4143 narrow trim passage set?
It ships as a complete set: both trim plates, the tubular latch, and the strike plate. The latch is a 28 degree unit and the faceplate is available round corner or square corner to match the existing mortise in the door edge. You still choose the knob or lever style separately, since the 4143 plate accepts any Emtek brass knob or lever.
6) Can I mix knob and lever styles on the Emtek 4143 STRETTO plate?
The 4143 accepts any Emtek brass knob or lever, and you pick the inside trim style when ordering. Choices run ten levers (Aurora, Bryce, Cimarron, Cody, Durango, Lariat, Mariposa, Montrose, Teton, Yuma) and fifteen knobs including Butte, Egg, Round, Winchester, Bristol, Hampton, Lowell, Windsor, Astoria, Diamond, Georgetown, Modern Disc, Modern Square, Old Town and Providence. Remember that a lever choice brings handing into play; a knob is symmetric.
7) Is the Emtek 4143 STRETTO lockset suitable for a commercial office or apartment corridor?
Emtek lists the 4143 as residential hardware. It is a tubular passage set in brass, sized for interior doors in homes and light residential settings, including high-end multi-family unit interiors. For a commercial corridor or anything on a fire-rated or high-traffic opening, spec a commercial-grade cylindrical or mortise lock instead.
8) What finishes does the Emtek 4143 STRETTO arched lockset come in?
Three: Flat Black, Medium Bronze, and Tumbled White Bronze. All three are on solid brass trim, so the finish wears into the base metal rather than off a plated shell. If you are matching other openings in the house, the same finish codes carry across Emtek's brass collection knobs and levers.
