Passage only. The 5106 lever with 5048 rose is a knob-or-lever set paired with roses with no privacy or locking feature, so it latches a door closed but gives you no thumbturn and no keyway. For a bed or bath you need a privacy set instead, and for an entry you need a keyed function.

The lever itself is reversible, so one part covers left and right hand doors. Ordering is still split by hand when you buy a single side: the choices are Half Pair Left Hand, Half Pair Right Hand, Pair, and Pair (PINNED). Full pairs cover both faces of the door.

They are both lever handle trim, but they are not the same part. The Baldwin Estate 5106 lever with 5048 rose is an Estate Series lever handle with a round rose, a 2-3/8 inch backset, 2.625 inch projection, and a reversible hand, so one order covers either a left or right hand door. The Imperial USA TH1100 Series lever handle is sold hand-specific as a left hand unit, so the hand of the opening has to be confirmed before ordering. If you need a single item that works on either swing, the 5106 reversible lever is the one to specify.

The Baldwin Estate 5106 lever with 5048 rose is a passage set - lever and roses with no privacy or locking feature - intended for doors that only need to latch, such as closets, hallways, and pass-through openings. It uses the standard 2-1/8 inch bore with a 2-3/8 inch backset and fits doors 1-3/8 to 1-3/4 inch thick. For a bathroom or bedroom that needs to lock, specify a privacy or keyed function set instead; a passage trim cannot be converted to one. Among lever trim comparables, the Imperial USA TH1100 Series lever is a hand-specific left hand handle rather than a privacy solution.

Projection is 2.625 inches off the door face and the lever grip runs 3.75 inches. Worth checking against a door that swings into a tight corridor or against a wall, and against adjacent trim or a door stop position.

It is classified as residential hardware, a tubular passage set in Baldwin's Estate line. For a commercial corridor or anything on a rated opening you want a commercial-grade cylindrical or mortise lockset instead.

Yes. The passage set ships with what is needed to mount it on the door, including the latch, and Baldwin publishes an installation guide for the interior latch. No separate trim or rose kit is required for a standard 2-1/8 inch bore.

For finish matching, the Baldwin Estate 5106 lever with 5048 rose is the broader option: it is offered in 14 finishes including polished brass, non-lacquered brass, vintage brass, satin brass, polished nickel, satin nickel, graphite nickel, oil rubbed bronze, distressed oil rubbed bronze, Venetian bronze, satin black, and polished chrome. The Imperial USA comparable is identified by series, TH1100, and hand rather than by a decorative finish range. The 5106 is also ordered as a pair, a pinned pair, or a single half pair by hand, which helps when you are replacing one side of an existing set.

Both give you levers for both faces of the door. The PINNED option is the pinned-spindle version, ordered when the lever needs to be fixed to the spindle rather than left as the standard pair assembly. If you are doing a straightforward passage door, the standard Pair is the normal order.

Within lever handles we also carry the Imperial USA TH1100 Series lever, offered in a left hand version. It is a different look and a different family, so it will not match Estate Series trim on other doors, but it is an alternative if you are outfitting an opening on its own rather than matching a set.
