Emtek LC4-PRVDV Drive-in Latch, Privacy Function

Yes. The LC4-PRVDV is an adjustable-backset latch that sets to either 2-3/8 or 2-3/4 inches, so it covers both of the standard residential borings. It's also ordered by backset, in 2-3/8 and 2-3/4 versions, so pick the one matching your door and adjust from there. The cross bore has to be 2-1/8 inches and the door 1-3/8 to 1-3/4 inches thick.

That's exactly what it's for. The LC4-PRVDV is the privacy/bed/bath function latch, non-keyed, so it pairs with a knob or lever that locks from inside with a thumbturn or push button and releases with an emergency tool from the hall. If you need a keyed exterior door, this is the wrong part, that job takes an entry-function latch.

Yes, the LC4-PRVDV is sold as a replacement part on its own, so if the knob or lever trim is fine and only the latch failed, you replace the latch and reuse the rest. It's a tubular latch, and it's brass. Order it in the backset your door is bored for.

The Emtek LC4-PRVDV is a privacy/bed/bath function drive-in latch. The Deltana DLP23875 is a drive-in latch with adjustable 2-3/8 inch or 2-3/4 inch backset carrying a passage/privacy function, so one part number covers both the bedroom and bath doors and the hall and closet doors on the same job. Both use the same adjustable backset, so the bored hole in the door does not change.

The Emtek LC4-PRVDV is built for privacy/bed/bath function and is non-keyed, so it is not the latch for a keyed opening. The Deltana DLE23875 is an adjustable drive-in latch with an entry function, which is the one that pairs with a keyed lockset.

No handing to specify. It's a tubular privacy latch with a beveled spring latchbolt that reverses, so the same part serves a left-hand or right-hand door. What you do have to get right is the backset (2-3/8 or 2-3/4 inch) and the nose bolt finish, brass or chrome.

The LC4-PRVDV is privacy function only, non-keyed, so it won't serve a keyed entry knob. Deltana's DLE23875 drive-in latch is the entry-function counterpart and covers 1-3/8 to 2 inch doors. Same style of part, different function, so match the function of the lockset you're repairing before anything else.

For a residential portfolio, one part number covers most of it. The LC4-PRVDV adjusts between the 2-3/8 and 2-3/4 inch backsets and handles 1-3/8 to 1-3/4 inch doors, which is the range of ordinary interior doors, and it's non-handed so it goes on either swing. It won't cover an entry door lockset (privacy function only) or any door thicker than 1-3/4 inches.

The Emtek LC4-PRVDV is a residential privacy/bed/bath drive-in latch with a brass body. Where a UL rated latch is called for, the Kwikset 83521 RCAL plain latch is UL 3 hour and fits BBL, KNL, CNL and PLL locksets, and the Kwikset 83518 RCAL adjustable square drive latch is also UL 3 hour. Both are Kwikset-prepped parts, so confirm the lockset they are going into.

No. The Emtek LC4-PRVDV is a privacy/bed/bath drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset. The Kwikset 84290 square corner plainlatch is a fixed 2-3/8 inch backset part and functions as a deadbolt strike plate item, not the privacy latch that drives the bed and bath turn function. If the opening needs an Emtek privacy latch, the closest drive-in equivalents are the Deltana DLP23875 passage/privacy drive-in latch.

Only for looks, and only on the door edge. The nose bolt finish is the visible collar and latchbolt at the edge of the door, so match it to the finish of your knob or lever trim, brass with warm finishes, chrome with satin nickel or polished chrome. Both are available in either backset.

The Emtek LC4-PRVDV is a single privacy/bed/bath drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset, so one item covers both common bore layouts. The Deltana DLP23875 is likewise an adjustable 2-3/8 inch or 2-3/4 inch drive-in latch in passage/privacy function and lists a 1-3/8 inch to 2 inch door thickness range, which is the one to carry where slab thicknesses across the property run past 1-3/4 inch.
