The best narrow modern rectangular pocket door mortise lock depends on whether you need privacy or keyed access, plus whether the lock fits your door thickness and existing cutout. The Emtek options are the closest match to a narrow rectangular mortise design, with privacy and keyed functions in several finishes. Lethato is a separate, reversible privacy latch option with a fixed backset and stated door-thickness range. Compare the product details below before ordering, especially the installation dimensions and function.

| Emtek Satin Nickel | Keyed | Handing not required |
Emtek Narrow Rectangular Privacy Lock, Flat Black

Best for: Buyers who want a narrow rectangular Emtek mortise lock for a room that needs a privacy function. Its listed plate dimensions are 2 by 7 1/4 inches, which gives shoppers specific measurements to compare against the door and existing hardware.
The product is made to order, and the listed details say to specify door thickness. Typical thicknesses are stated as 1 3/8 to 1 3/4 inches. Choose this option if the flat-black finish and privacy function suit the room. Confirm the door thickness before placing an order; the listing does not establish a universal fit.
Emtek Narrow Rectangular Privacy Lock, Oil Rubbed Bronze

Best for: Buyers seeking an Emtek privacy lock in oil rubbed bronze. The listed product is part of Emtek’s narrow modern rectangular pocket door mortise range. The supplied feature information describes the brand’s focus on customizable door hardware, quality, and style, but does not provide this item’s plate dimensions or door-thickness range.
Choose this version when the finish is the priority and you can verify the fit from the product listing or seller. Avoid assuming it shares every specification with another Emtek finish or function. Its stated function is privacy, not keyed access.
Emtek Narrow Rectangular Keyed Lock, Bright Chrome

Best for: Buyers who need the keyed function rather than a privacy lock and want a bright-chrome finish. The listed details say handing is not required, the minimum door thickness is 1 3/8 inches, and trim plates are 1/8 inch thick.
The product information says to specify door thickness for all functions and to specify exterior or interior for a split finish. Check those ordering requirements before purchase. Choose this model if keyed access is needed; avoid selecting it when a simple privacy function is the actual requirement.
Lethato Reversible Privacy Pocket Door Lock

Best for: Buyers comparing a matte-black privacy latch with a stated fit range of 1 3/8 to 1 15/16 inches. Lethato lists a fixed, nonadjustable 2 3/8-inch backset and reversible installation. The product information says it can use an existing round door hole without slotting the door edge.
The listed material is zinc alloy, with an electroplated surface and matte-black option; the feature text also mentions brushed nickel. This is not described as the same narrow rectangular mortise format as the Emtek products. Avoid this option if your installation requires an adjustable backset or a specific rectangular mortise plate.
Emtek Narrow Rectangular Keyed Lock, Satin Nickel

Best for: Buyers who want a keyed Emtek pocket door lock in satin nickel. The available feature information says handing is not required and notes that exterior or interior should be specified for a split finish.
The supplied details do not state plate dimensions or a door-thickness range for this finish. Confirm both fit and any thickness-ordering requirements before buying. Choose it for keyed access and the satin-nickel finish; do not treat the limited specification text as confirmation that it fits a particular door.
Buying Guide: How to Choose a Pocket Door Mortise Lock
Do you need privacy or keyed access?
A privacy function is intended for rooms where occupants need a privacy lock, while a keyed function is the relevant choice when the product must provide keyed access. The listed Emtek options include both functions. Decide on the function first, then compare finish and fit. Do not substitute one function for the other based only on appearance.
Will the lock fit your door?
Measure the door thickness and compare it with the product’s stated requirements. The Flat Black Emtek listing asks buyers to specify thickness and gives typical thicknesses of 1 3/8 to 1 3/4 inches. The Bright Chrome keyed listing gives a minimum of 1 3/8 inches. Lethato states a range of 1 3/8 to 1 15/16 inches, but its backset is fixed at 2 3/8 inches.
Does the plate match your existing cutout?
Compare the plate dimensions, lock body, backset, and existing door preparation before ordering. The Flat Black Emtek listing specifies a 2-by-7 1/4-inch plate. The supplied details for other Emtek finishes do not include plate dimensions, so verify their measurements separately. Lethato describes using a reserved round hole, which may not suit a door prepared for a different mortise design.
Which finish should you select?
Choose among flat black, oil rubbed bronze, bright chrome, and satin nickel based on the room’s other hardware. Finish alone does not confirm that two models have the same function or dimensions. Review the exact product variant and order details, particularly when a split finish must be specified.
