It does not lock. Passage function means the lever retracts the latch from either side at all times, with no key, no thumbturn, and no pushbutton. That makes it right for hallways, closets, and pantries. For a bedroom or bathroom you need a privacy set instead.

It is built as residential hardware in Baldwin's Estate Series, so it suits homes, condos, and high-end multi-family interiors rather than heavy commercial traffic. For a corridor or classroom door, a Grade 1 commercial passage lever like the Falcon K101 or the Dexter C1000 passage is the correct class of product.

No. The 5106 tops out at 1.75 inches. For a 2 inch door look at a lever rated to that thickness, such as the Hager 2510 passage (1-3/8 to 2 inches) or the Falcon K101 (1-3/8 to 2-1/4 inches).

The Baldwin 5106 fits doors from 1.37 inch to 1.75 inch. For a thicker leaf, the Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, the Hager 2510 Grade 2 passage lever covers 1-3/8 inch to 2 inch, and the Lockey 2835 keyless passage lever lock covers 1-3/16 inch to 2 inch.

The Baldwin 5106 with 5048 rose is a residential Estate Series passage leverset. For high-traffic commercial openings, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, and covers 1-3/8 inch to 2-1/4 inch doors. The Corbin Russwin CL3110 is also a Grade 1 vandal resistant passage/closet lever, fire rated, for 1-3/4 inch to 2 inch doors. Both are passage function like the 5106, so the door prep intent is the same, but they are specified for commercial duty rather than residential.

The Baldwin 5106 with 5048 rose is passage function only, with no privacy or locking feature, so it is wrong for a bathroom. For privacy, the Kwikset 300BRNL RDT Breton is a Grade 3 privacy leverset for 1-3/8 to 1-3/4 inch doors, and the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 to 2 inch doors.

No handing to specify. The 5106 lever is reversible, so one set covers left and right hand doors and you can standardize on a single part number across a house or a floor of units.

Projection off the face of the door is 2.625 inches, and the lever grip measures 3.75 inches. Worth checking against tight door-to-wall or door-to-casing clearances and against adjacent doors that swing past each other.

The passage set ships complete with the latch and strike hardware needed to mount it on a prepped door. No separate latch or cylinder purchase, since passage function is non-keyed.

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). That range lets you match passage doors to entry and bath hardware in the same finish family across a whole house.

For rental turns where the Estate Series price point is more than the door needs, round-rose passage leversets in the set include the Bravura Atlanta and Bravura Orlando (both Grade 2), the Callan Asheville in satin nickel (Grade 3), and the Kwikset 200BRNL Breton with round trim (Grade 3, 1-3/8 to 1-3/4 inch doors). All are passage function like the 5106, so no keying to coordinate.

It is a bored tubular lockset, installed in the 2-1/8 inch cross bore with a 2-3/8 inch backset. That is the standard interior bore, so it swaps straight into a door that already carries a knob or lever of the same prep. The 5048 rose is round.

The Baldwin 5106 is part of the Estate Series and is offered in 11 finishes including polished nickel, satin brass and oil rubbed bronze. If the decorative finish range is not the driver, the Kwikset 200BRNL RDT Breton is a Grade 3 passage leverset for 1-3/8 to 1-3/4 inch doors, and the Callan Asheville is a Grade 3 passage leverset in satin nickel. Both are passage function with no locking, the same as the 5106.

Dummy trim is the common mix-up. The Baldwin 5106 is a working passage set with a latch that retracts when the lever is turned. A dummy such as the BEST 7KC Series single dummy trim, the BEST 9K Series 1DT Grade 1 single dummy trim, or the Emtek Classic Cortina dummy pair is surface-mounted trim with no latch at all, used on inactive or closet doors that are held by a ball catch. Order dummy trim only where nothing needs to latch.

The Baldwin 5106 uses the 5048 round rose. If the other doors carry square trim, the Bravura Tampa is a Grade 2 passage leverset with square trim. If round is fine but a different lever shape is wanted, the Bravura Atlanta and Bravura Orlando are Grade 2 passage leversets with round trim.

Both are non-keyed cylindrical passage levers for hall and closet doors. The Accentra 5301LN Augusta is a Grade 2 cylindrical lever lock in the 5300 Series with the Augusta lever design; the Accentra 4601LN is the same passage function in the 4600 Series. The Baldwin 5106 is an Estate Series residential set with a 2-3/8 inch backset and a reversible lever, so confirm backset and trim style match before swapping.

The Baldwin 5106 is passage only with no locking feature. For a keyless lever in the same opening, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, the Lockey 2835DC adds double combination, and the Lockey 1150 is a heavy duty mechanical keypad lever set with passage function for 1-1/8 inch to 2 inch doors. The Delaney LP250 is an electronic keypad leverlock rated Grade 2.

Design Hardware offers the X75 passage lever lockset as a Grade 1 flat lever and the J75 passage lever lockset as a Grade 2 flat lever, both listed for 1-3/4 inch doors, which lets a facility run one lever look at two duty levels. The Baldwin 5106 is a single residential Estate Series passage set and is not offered as a graded commercial pair.

The Baldwin 5106 is offered in 044 Satin Brass with the round 5048 rose. A comparable is the Bravura Miramar with round trim passage leverset in US4 satin brass, a Grade 2 passage set. Both are non-locking passage function; the Baldwin is an Estate Series residential set.
