Emtek 8243 STRETTO Narrow Trim Lockset, 1-1/2" x 11" Modern Rectangular Non-Keyed, Brass Tubular, Privacy

Yes, the cross bore is the usual 2-1/8 inches, so an existing bored door works. What differs is the face prep: the STRETTO narrow trim uses a narrow 1-1/4 inch door prep with 3-3/8 inch center-to-center hole spacing, not the single round hole a knob rose covers. On a door already drilled for a standard rosette lockset you will need to add the two mounting holes at 3-3/8 inch centers. Backset is 2-3/8 inches standard, with 2-3/4 inches available if the existing bore sits farther off the edge.

Measure from the edge of the door to the center of the bored hole. That distance is the backset. The 8243 ships 2-3/8 inches unless you specify 2-3/4 inches, and backset is a required choice at order time. Residential interior doors are most often 2-3/8 inches; 2-3/4 inches shows up on heavier or commercial-style openings. Getting it wrong means the latch will not reach the strike.

Privacy only, non-keyed. The 8243 is a bed and bath function: it locks from inside with a thumbturn or push button and has no key cylinder. Use it on bedrooms, bathrooms, and any interior door that needs occupancy privacy, not on an entry door or anything that needs to be locked from the outside. For a keyed opening you need a keyed entry or handleset function instead.

Handing is a required selection, right hand or left hand, on every order. It matters when you pick a lever: levers are handed and a left hand lever on a right hand door points uphill. Knobs are symmetrical, but the order form still asks, so determine the hand from the door before you order. Stand on the outside of the door, the side it swings away from; hinges on the right is right hand, hinges on the left is left hand.

It ships as a complete set: both trims, the latch, and the strike plate, with a 28 degree latch supplied. The latch faceplate is available round corner or square corner, so match it to the mortise already cut in your door edge. What is not in the box is the knob or lever, which you choose separately from the Emtek brass knob and lever range. Screws for the strike and trim are part of the set; nothing else is required for a standard bored door.

Narrow trim is for doors where a round rose does not suit the look or does not fit the rail. The STRETTO plate measures 1-1/2 by 11 inches, a long modern rectangular escutcheon rather than a compact round rose, and it drills a narrow 1-1/4 inch door prep with two holes at 3-3/8 inch centers. That vertical plate reads as contemporary trim and covers more of the stile. A standard rosette set is the simpler retrofit on a door already bored for one, since it needs no additional prep. Pick narrow trim when the design calls for it and the door is being prepped fresh or can take the extra holes.

Yes, and that is the usual way it is specified. The 8243 is the privacy version of the STRETTO modern rectangular narrow trim family, so it takes the same 1-1/2 by 11 inch plate and the same brass knob and lever styles as the other functions in the line. Order privacy sets for bedrooms and baths and passage sets for closets and halls in the same finish and same lever, and the openings read identically across the floor. Finish choices are Oil Rubbed Bronze US10B, Polished Nickel US14, Satin Nickel US15, Flat Black US19, Polished Chrome US26, Unlacquered Brass US3NL, and Satin Brass US4.

The 8243 is a residential-duty product. It is a brass tubular privacy set built for interior doors in homes and residential-style interiors, which covers single-family, high-end multi-family unit interiors, and hospitality guest rooms where the look matters. For back-of-house, corridor, or high-traffic commercial openings, specify a commercial-grade bored or mortise lock instead.

The inside trim style is a required choice from Emtek's full brass knob and lever range, roughly 90 options. That spans contemporary levers such as Stuttgart, Helios, Athena, and Poseidon; the modern bar and square families including L-Square, T-Bar, and R-Bar in Faceted, Hammered, Knurled, Tribeca, Straight Knurled, and White Marble; traditional levers like Rope, Ribbon and Reed, and Santa Fe; and knobs from the Ace and Spoke through Egg, Melon, Providence, and the crystal knobs. Pick the same style and finish across the door set and the whole opening matches.

Brass throughout, both the trim material and the substrate, with a tubular latch mechanism. Brass is what allows the range of plated and living finishes, including Unlacquered Brass US3NL, which is a raw brass that patinas with handling rather than holding a fixed color. If you want the finish to stay as delivered, pick a plated option such as Satin Nickel US15 or Polished Chrome US26 instead.
