Weslock 12725X Drive In Adjustable Spring Latch

Drive-in is exactly what it says: the 12725X spring latch has a round collar that drives into the 1 inch cross-bore in the door edge, so there's no rectangular faceplate mortise to chisel. That's the reason to pick it on a prehung or a factory-bored slab where the edge has never been routed. If your door edge already has a squared-off faceplate mortise from an old latch, a drive-in leaves that pocket exposed and you want a square or radius corner faceplate latch instead.

It's an adjustable latch, so one part covers the two backsets used on residential doors, 2-3/8 inch and 2-3/4 inch. You extend or collapse the latch body to match the distance from the door edge to the center of the bore rather than ordering a backset-specific part. Measure the existing bore before you order: if the center of the 2-1/8 inch hole sits 2-3/8 inches from the edge you set it short, at 2-3/4 inches you set it long.

Spring latch only, meaning it's the beveled, self-latching bolt that a knob or lever retracts. It is not a deadbolt and gives you no deadlocking security on its own. If you're replacing the bolt in a Weslock deadbolt you need a deadbolt latch, not the 12725X. On an entry door most people run both: the lever with this spring latch, and a separate deadbolt above it.

For a fire-rated opening, look at the Kwikset UL-listed adjustable latches: the Kwikset 83518 RCAL adjustable square drive latch is UL 3 hour, and the Kwikset 83521 RCAL plain latch is UL 3 hour for BBL, KNL, CNL and PLL trim. The Weslock 12725X drive in adjustable spring latch is not offered with a UL fire rating, so on a labeled door the specification is a latch that carries the UL listing to match the door label.

No. The Kwikset 84290 square corner plainlatch is a faceplate-style latch: it has a square-corner faceplate that seats in a mortised pocket routed into the door edge. A drive-in latch such as the Weslock 12725X drive in adjustable spring latch is driven into the bore with no faceplate mortise. If the door edge is already routed for a square-corner faceplate, a drive-in latch will leave that pocket open, and if the edge is unrouted, a faceplate latch requires cutting it.

Deltana makes two drive-in adjustable latches worth looking at, and both state a door thickness range of 1-3/8 to 2 inches. The DLE23875 is the entry function, for a keyed lever or knob. The DLP23875 is the passage/privacy version with adjustable backset at 2-3/8 or 2-3/4 inches, for bedroom, bath, and closet doors. Pick by function first, because an entry latch and a passage latch are not interchangeable in the lockset they belong to.

No. A drive-in spring latch goes into a bored door with a 2-1/8 inch cross bore and a latch hole in the edge, which is not how a pocket door is prepped. Pocket door hardware uses a mortised tubular latch with its own faceplate, like the Emtek 83228 faceplate and screw set for a tubular pocket door privacy latch, square corners. Different prep, different part.

Across a fleet it covers both common backsets from a single part, so one bin serves doors bored at 2-3/8 and at 2-3/4 inches, which is where mixed-vintage buildings usually bite you. Where it stops: it is a spring latch for knob and lever function, so deadbolts still need their own bolt, and any fire rated door needs a latch carrying its own rating. Stock it by finish to match the lever families already hanging on your doors.

An adjustable latch covers both common residential backsets from one part - the Deltana DLP23875 adjusts to 2-3/8 inch or 2-3/4 inch, and the Weslock 12725X is an adjustable spring latch. A fixed-backset part such as the Kwikset 84290 square corner plainlatch is built for a 2-3/8 inch backset only. For a fleet of doors where the bore center varies from opening to opening, the adjustable latch is the one part number that fits both; for a standardized 2-3/8 inch prep, the fixed latch removes the field adjustment step.

No. The Emtek LC9-DBLTCH EMPowered motorized deadbolt latch is a deadbolt latch - a deadlocking bolt with no spring return, driven by the EMPowered motorized deadbolt above it. The Weslock 12725X drive in adjustable spring latch is a spring latch with a beveled bolt that retracts when the door closes against the strike. A deadbolt latch will not self-latch on close and does not work with knob or lever trim, so the two are not interchangeable in the same bore.

No. A pocket door takes a dedicated tubular pocket door privacy latch, and the Emtek 83228 covers the faceplate and screws for one in a square corner. The Weslock 12725X drive in adjustable spring latch is a swing door latch with a beveled spring bolt that catches a strike on the jamb, which is not how a pocket door latches. Match the pocket door hardware itself rather than substituting a swing door latch.

Trim compatibility is stated on the latch. The Kwikset 83521 RCAL plain latch is listed for BBL, KNL, CNL and PLL trim, so it is the part to specify when those lever and knob families are already on the openings. The Weslock 12725X drive in adjustable spring latch is a Weslock part and pairs with Weslock knob and lever trim, and it comes in oil rubbed dark bronze, satin brass and satin chrome so the exposed faceplate can be run to match the existing finish across a set of doors.

Three finishes: oil rubbed dark bronze, satin brass, and satin chrome. Only the drive-in collar shows once the latch is installed, and it sits on the door edge where the strike side sees it, so match it to the lever or knob you're using rather than to the hinges. On an interior opening where the edge is rarely looked at, any of the three works.
