Emtek 2291 Screen Door Locks - Rectangular Style - Solid Brass or Sandcast Bronze

Yes, handing is required on the 2291. It ships as a left hand (LH) or right hand (RH) unit and there is no reversible or non-handed version. Stand outside the screen door, on the side the door swings away from, and note which side the hinges are on. Get it backwards and the lever or knob throw ends up on the wrong face. Every finish is offered in both hands, so pick the finish first and the hand second.

No on both counts. The 2291 is not sold knob by knob or lever by lever, and it is not available split finish. Whatever configuration Emtek builds for this model is what you get, in one finish on both faces. If a split finish matters for your opening, this is the wrong model to spec.

It is a mortise lock. The 2291 comes with a mortise lock body that seats into a pocket cut in the door stile, not a surface mounted latch that screws onto the face. That means the screen or storm door stile has to be deep enough to take the case, and the install is a routed pocket plus a strike on the jamb. If your door stile is too thin to mortise, or you want a screw-on retrofit with no cutting, a surface mounted storm door latch is the right direction instead.

Seven finishes, and they span both the sandcast bronze look and the polished brass look: Medium Bronze (MB), Tumbled White Bronze (TWB), Oil Rubbed Bronze (US10B), Satin Nickel (US15), Flat Black (US19), Polished Brass Lifetime (US3), and Unlacquered Brass (US3NL). All seven are available in both left and right hand. If you are matching a bronze entry set on the main door, MB and TWB are the sandcast finishes; if the house runs unlacquered brass that patinas, US3NL will age along with it rather than staying bright like US3.

The 2291 is solid brass, and the sandcast bronze finishes are cast bronze substrate. Both are non-ferrous, so a screen or storm door set sitting in weather is not going to rust the way a plated steel latch does. Unlacquered Brass (US3NL) is the one finish that will change over time by design, it develops a patina outdoors. If you want the appearance held steady, Polished Brass Lifetime (US3), Satin Nickel (US15), or Flat Black (US19) are the stable choices.

It is part of Emtek's Sandcast Bronze collection, so it is meant to sit alongside the sandcast entry hardware rather than approximate it. Medium Bronze and Tumbled White Bronze are the sandcast finishes to pair with a sandcast door set. The shape is rectangular, so it reads as a squared plate rather than a rounded or oval one. If the entry hardware on the opening is a different Emtek collection, match on the finish code (US10B, US15, US19, US3, US3NL are the standard codes carried here) rather than on the collection name.

Across a set of openings you can standardize on the model and finish, but not on a single part number. Because the 2291 is handed, doors that swing opposite ways need different units, so count your left hand and right hand openings before ordering. All seven finishes are made in both hands, so the fleet still looks identical. Bear in mind this is residential grade hardware, which suits multi-family and single-family screen doors rather than high-traffic commercial entrances.
