Yes. The 5106 privacy lever with the 5048 rose covers doors from 1-3/8 up to 1-3/4 inches thick, so it handles both older interior doors and standard modern ones. Backset is 2-3/8 inches, the usual interior bore spacing, and it drops into a standard 2-1/8 inch cross bore.

No handing to specify. The 5106 lever is reversible, so the same set works on a left or right hand door and you set the lever direction during install. Useful if you're buying several for a house or a unit turn and don't want to count door swings first.

Privacy function, no key. The 5106 locks from the inside for a bedroom or bathroom and has no exterior cylinder. If you need a keyed opening, this is the wrong function. For a closet or hall door that shouldn't lock at all, a passage set is what you want instead.

It's a residential-duty tubular lockset, built for homes and residential units rather than commercial traffic. For a commercial bath or bedroom opening, look at a Grade 1 or Grade 2 cylindrical privacy lock instead, such as the Arrow MK02-TA privacy lock, which is fire rated and fits 1-3/4 to 2 inch doors.

The Baldwin 5106 is a privacy-function cylindrical leverset on a 2-3/8 inch backset. The nearest match by function in another brand is the Kwikset 300BRNL RDT Breton privacy lever set, which is also a privacy/bed/bath lever and is rated Grade 3, with a door thickness range of 1-3/8 to 1-3/4 inches. The Baldwin 5106 fits doors from 1.375 to 1.75 inches, so both cover the same standard residential door. The Hager 2540 Withnell is another privacy cylindrical lock, Grade 2, covering 1-3/8 to 2 inch doors for a heavier commercial-style build.

The Baldwin 5106 is a privacy lever, which adds the bed and bath locking turn. For a hall or closet opening that only needs a latch, a passage-function lever is the right part: the Accentra 5301LN Augusta is a Grade 2 passage/hall/closet cylindrical lever, the Bravura Atlanta round-trim passage leverset is Grade 2, and the Callan Asheville is a Grade 3 passage leverset. The Bravura Atlanta and Bravura Orlando both use round trim, which reads closest to the round rose on the 5106.

The Baldwin 5106 is a residential leverset. For commercial traffic in the same lever format, look at Grade 1 heavy duty options: the Falcon K101 is a Grade 1 passage cylindrical lock, heavy duty, fire rated, covering doors 1-3/8 to 2-1/4 inches, and the Falcon T101 is a Grade 1 heavy duty passage lever. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever, fire rated, for 1-3/4 to 2 inch doors. Note that those three are passage function, not privacy, so they latch without locking.

The Baldwin 5106 covers doors from 1.375 inches up to a maximum of 1.75 inches, so a 2 inch door is outside its range. Levers that reach 2 inches include the Hager 2510 Withnell passage, Grade 2, 1-3/8 to 2 inches; the Deltana 6201 Manchester entry lever, 1-3/8 to 2 inches; and the Falcon K101, Grade 1 passage, 1-3/8 to 2-1/4 inches. Match the function you actually need, since the Hager 2510 and Falcon K101 are passage and the Deltana 6201 is entry.

No. The Baldwin 5106 is a privacy lever, which locks from the inside only with no outside key cylinder. For a keyed opening in lever form, the Hager 2525 is a Grade 2 commercial cylindrical entry lock with lever handle for 1-3/8 to 2 inch doors, the Cal-Royal AG00 is a Grade 2 entrance lever with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset, and the Falcon B511CP6D is a Grade 2 entry/office cylindrical lever. The Cal-Royal AG00 shares the 2-3/8 inch backset the 5106 uses, so the existing bore and latch prep carries over.

Projection is 2.625 inches off the door face, with a 3.75 inch lever grip. That matters where a door swings against a return wall, a cabinet, or a second door in a tight bath: measure your clearance to the nearest obstruction before committing, since a lever needs room for a hand as well as the handle.

Eleven finishes: Polished Brass (003), Non-Lacquered Brass (031), Vintage Brass (033), Satin Brass (044), Polished Nickel (055), Satin Nickel (056), Graphite Nickel (076), Oil Rubbed Bronze (102), Venetian Bronze (112/11P), Satin Black (190) and Polished Chrome (260). Non-lacquered brass is the one that will patina over time rather than hold its as-shipped look, so keep it off a fleet spec if you want every door to age alike.

The 5106 comes on the 5048 rose, which is round. If the other openings in the unit are wearing a square or beveled rose, the trim won't read as a matched set even in the same finish. Match the rose number, not just the finish code, when you're standardizing a whole floor.

No. The set ships with everything needed to mount it on a prepped door, latch and strike included. What you do need is a door already bored to the standard 2-1/8 inch prep with a 2-3/8 inch backset; if your existing bore is a 2-3/4 inch backset, this set won't line up.

For a rental turn where the finish doesn't have to be decorative brass, the Kwikset 300BRNL Breton privacy lever is a Grade 3 privacy set covering 1-3/8 to 1-3/4 inch doors, the same thickness range the 5106 handles. The Baldwin is the choice when the trim has to match higher end hardware elsewhere in the home.

Dummy levers. They mount the same lever and rose but have no latch and no locking mechanism, so they only pull a door closed. The Callan Bentley is a Grade 2 dummy lever, the BEST 7KC single dummy trim is Grade 2 non-keyed, the BEST 9K 1DT single dummy trim is Grade 1 heavy duty non-keyed, and Emtek Arts and Crafts and Cortina dummy levers ship as pairs. The Baldwin 5106 is a privacy lever with a working latch and a bed and bath lock, so a dummy is not a like-for-like swap.

The Baldwin 5106 pairs a lever with the round 5048 rose in a privacy function. If a knob is wanted on the same style of opening, the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed, Grade 1, fire rated, for 1-3/4 to 2 inch doors. Confirm the door thickness first, since the Baldwin 5106 tops out at 1.75 inches and the Arrow MK02-TA starts there.

The Baldwin 5106 locks with a bed and bath privacy turn and takes no code. For pushbutton entry in a lever, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1-3/16 to 2 inches, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function for 1-1/8 to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. These control who enters rather than giving an occupant a privacy turn from inside.

No. The Baldwin 5106 is a privacy lever, which is locked and released by the occupant inside the room. For asylum and institutional openings where staff control the door from outside, the Dexter C1000 F87 asylum is a Grade 1 cylindrical lock for 1-3/8 to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob and a conventional cylinder in the Schlage C keyway.

The 5106 lever is sold in privacy function only. To keep the same lever and 5048 round rose across a hallway, order the passage version of the 5106 for closet and hall doors and the privacy version for bed and bath. If you're mixing brands instead, the Bravura Miramar round trim passage leverset is a Grade 2 round rose option.

The Baldwin 5106 uses a round rose. For square trim in a comparable cylindrical leverset, the Bravura Tampa is a Grade 2 passage leverset with square trim. It is a passage function, so it latches without locking, unlike the privacy function on the Baldwin 5106.
