It goes into standard door prep, so if the pocket door already has the round mortise cutout from a previous privacy lock, this drops in. The round trim is 2-7/16 inches in diameter, which is what covers the face of the door around the cutout. Measure the existing escutcheon on the door you are replacing: anything at or under 2-7/16 inches across will be covered.

Privacy function means it locks from the inside only, with no key. That is the bed and bath setup: you thumb-turn it closed from inside the room, and it is meant for bathrooms, bedrooms and closets on a pocket door. It is not a keyed or entry lock, so do not spec it for a door that needs to be secured from the corridor side.

For thicker slabs, look at the Weslock 0677 Round Privacy Pocket Door, which is listed for 1-3/8 inch to 2 inch doors. The Cal-Royal SDL16 pocket door privacy lock covers 1-3/8 inch to 1-3/4 inch. Both are the same privacy function as the Delaney Contemporary Round, and the Weslock is also a round-trim design if you are trying to keep the same look.

The Weslock 0677 Round Privacy Pocket Door is the nearest match in form and function - it is a round privacy pocket door set, the same round trim shape and the same privacy function as the Delaney Contemporary Round, which is catalogued with a Privacy lock function and a 2-7/16 inch diameter round trim. The Weslock 0677 also states a door thickness range of 1-3/8 inch to 2 inch, so on thicker doors up to 2 inch it is the one to specify. Both are privacy sets, meaning they lock from the inside for a bath or bedroom pocket door and are not keyed.

Two peers publish their door thickness ranges. The Cal-Royal SDL16 Pocket Door Privacy Lock covers 1-3/8 inch to 1-3/4 inch, which is the standard interior and standard exterior door range. The Weslock 0677 Round Privacy Pocket Door covers 1-3/8 inch to 2 inch, so it reaches thicker slabs that fall past 1-3/4 inch. If the pocket door on the job measures over 1-3/4 inch, the Weslock 0677 is the one whose stated range covers it.

Shape of the cutout, mostly. The Delaney Contemporary Round is a 2-7/16 inch round trim, so it needs a round bore in the door face. A rectangular unit like the Trimco 1065 pocket door pull is a 2-1/2 by 2-3/4 inch privacy locking pull and needs a rectangular mortise. Pick the one that matches the prep already in the door, because converting a round hole to a rectangular one on a hollow-core pocket door usually means a new slab.

Three other privacy pocket and sliding door units are worth pricing against the Delaney Contemporary Round: the Cal-Royal SDL16 with decorative coined edges, the Trimco 1065 pocket door pull in a 2-1/2 by 2-3/4 inch rectangular format, and the Orca Hardware AH Series privacy latch for sliding doors. All four are privacy function, so functionally your residents get the same thing; the decision comes down to trim shape and finish matching what is already on the other openings.

It is built as a pocket door lock, which means it mortises into the edge and face of a door that disappears into a wall pocket and latches against the jamb. A surface-mounted barn door will not take it. For a sliding door that is not a pocket door, the Orca Hardware AH Series privacy latch is the one made for that application.

The Trimco 1065 Pocket Door Pull is a rectangular privacy locking pull measuring 2-1/2 inch by 2-3/4 inch, so it suits an opening where the other pocket doors or the door trim are squared off. The Cal-Royal SDL16 is a pocket door privacy lock with decorative coined edges, a different visual treatment again. The Delaney Contemporary Round is a 2-7/16 inch diameter round trim, so if the round profile is what does not suit the opening, the Trimco 1065 is the rectangular alternative in the same privacy function.

Not a direct one. The Orca Hardware AH Series Privacy Latch is built for sliding doors and carries a Privacy/Bed/Bath function, so it does the same job of locking a bath or bedroom from the inside, but it is a sliding door latch rather than a flush round pocket door trim like the Delaney Contemporary Round, which is a 2-7/16 inch diameter round set. If the door is a surface-mounted slider rather than a door that recedes into a pocket, the Orca AH latch is the right family. For a true pocket door prep, stay with a pocket door set such as the Cal-Royal SDL16 or Weslock 0677.

Zinc. The Contemporary Round privacy lock is a zinc body, not a plastic or stamped-sheet part, which is what you want on a bathroom pocket door that gets pulled and thumb-turned every day in a rental or a hotel room.

The Trimco 1065 is a pocket door pull with a privacy locking function, sized 2-1/2 inch by 2-3/4 inch in a rectangular format, and its function is listed as Privacy/Bed/Bath. The Cal-Royal SDL16 is a pocket door privacy lock in the SDL Series with decorative coined edges, function listed as Privacy, and it publishes a door thickness range of 1-3/8 inch to 1-3/4 inch. So the deciding factors are trim shape - rectangular pull versus a coined-edge lock - and whether you need a stated thickness range to hold against the slab on the job.
