It does not lock. This is a passage function, meaning it latches and pulls the door closed but has no privacy turn and no key. For a bathroom or bedroom pocket door you need a privacy version instead, such as the Cal-Royal SDL16 pocket door privacy lock or the Weslock 0677 round privacy pocket door.

No, not for a bathroom. Passage function has no privacy turn, so the occupant cannot secure the door. Go with a privacy pocket door lock: the Cal-Royal SDL16 covers 1-3/8 to 1-3/4 inch doors, the Weslock 0677 covers 1-3/8 to 2 inch doors, and the Trimco 1065 pocket door pull with privacy locking function is another option. Keep the Delaney passage for closets, pantries, and laundry pockets where nobody needs to lock the door.

The Delaney Contemporary Square pocket door lock is a passage function, so it pulls the door closed and releases without any locking. For a bathroom or bedroom pocket door you need a privacy function instead: the Cal-Royal SDL16 pocket door privacy lock has decorative coined edges and fits doors 1-3/8 inch to 1-3/4 inch thick, and the Weslock 0677 is a round privacy pocket door unit covering 1-3/8 inch to 2 inch doors. Order the Delaney where the opening is a closet, pantry, or laundry that never needs to be secured from inside.

No handing to specify. The face is square and symmetrical at 2-9/16 x 2-9/16 inches, and passage function has no turn or key to orient, so the same part works on a left or right sliding pocket door. Finish is the only choice you make on the order.

Only the face shape and how it reads against the rest of the trim. The Delaney Contemporary Square uses a square 2-9/16 inch face; the Weslock 0677 is a round pocket door unit. Both mount into the door edge and face prep. Pick the square face if the levers and plates in the space are square or rectangular, the round if the existing hardware is round rose. Note the Weslock is a privacy unit and the Delaney square is passage, so they are not function-for-function swaps.

The Delaney Contemporary Square is a zinc pocket door lock with a 2-9/16 inch by 2-9/16 inch face, passage function. The Trimco 1065 is a pocket door pull with a privacy locking function, measuring 2-1/2 inch by 2-3/4 inch, so its cutout is a different rectangle rather than the Delaney's square. If you are replacing one with the other, the existing mortise pocket will need to be reworked to match.

Pair the Delaney Contemporary Square passage pocket door lock on the closet and pass-through openings with a privacy unit on the bath. Among privacy options, the Cal-Royal SDL16 covers 1-3/8 inch to 1-3/4 inch doors and the Weslock 0677 covers 1-3/8 inch to 2 inch, so pick by the slab thickness in the building. The Delaney comes in 622 matte black, 625 bright chrome, and 619 satin nickel, which is what usually drives the pairing once function is settled.
