Baldwin 0413 Contemporary Mortise Door Bolt with 2-3/4" Backset Less Turn Piece

Less turn piece means the bolt mechanism ships without the operating turn piece, so you supply it separately or reuse the one already in the door. What does come with it is the bolt body, both a universal and a mortise strike, and the mounting hardware. If you want a complete bolt out of the box, you need the version that includes the turn piece; ordering the LTP on its own leaves you with nothing to throw the bolt with.

That is the job it is built for. The bolt mortises into the edge of the inactive leaf and throws into a strike, letting that leaf act as a fixed jamb for the active door. Two bolts, one at the head and one at the threshold, is the usual arrangement on a pair. Since the bolt is a 2-3/4 inch backset unit and includes both universal and mortise strikes, you can prep the head jamb or the sill for whichever strike suits the condition.

No extra strike purchase. Both a universal strike and a mortise strike come in the box, which covers the two usual situations: a mortise strike let into the inactive leaf or jamb for a clean flush finish, and the universal strike where you want a surface-applied or simpler prep. Mounting screws are included as well.

A mortise bolt is let into the edge of the door so only the turn piece and faceplate show, which is why it gets specified on double doors and French doors where the inactive leaf has to look finished. A surface bolt screws onto the face of the door instead, no routing needed, but it sits proud and is visible. The 0413 is the mortise type, so budget for the pocket to be routed into the door edge at a 2-3/4 inch backset. If the door is already hung and you do not want to pull it and rout it, a surface bolt is the easier retrofit.

Four finishes: 031 Non-Lacquered Brass, 056 Lifetime PVD Satin Nickel, 102 Oil Rubbed Bronze, and 260 Polished Chrome. Those are Baldwin's own finish codes, so ordering the same code as the levers, hinges or handlesets already on the opening keeps the bolt matched. Non-lacquered brass and oil rubbed bronze are living finishes that change with handling and age; PVD satin nickel and polished chrome hold their appearance.

No. It is a manually operated bolt thrown by a turn piece from one side only, with no cylinder and no key. It secures a door leaf in place; it is not a substitute for a deadbolt on an entry door, and it gives no security from the outside face of the door.

Brass and steel construction. The brass components are what let it be finished to match the rest of the Estate trim, and the steel carries the working load in the bolt itself. It is a residential-duty part, so it suits homes, condos and light multi-family openings rather than high-traffic commercial doors.

It is an Estate Series part with contemporary styling, so the faceplate detailing and the finish codes line up with the rest of the Estate collection. If the door already carries Estate levers or a handleset, specifying the same finish code gives you a matched opening.
