Featuring an adjustable backset for 2 3/8" or 2 3/4" door preps and a durable nickel radius corner faceplate, it offers both versatility and a sleek finish. With limited availability due to Weslock discontinuing this line, this latch is a rare find for professional-grade door hardware upgrades. ## Description The 12721 dead latch is compatible with Weslock standard 600 series knobs and is adjustable for either 2 3/8" or 2 3/4" backset door preps. It also fits many of series of keyed locks that have latches marked 600 series. It ships with a radius corner face plate, currently in nickel finish. The latch ships with the extension attached, but if you need a shorter latch, just pop off the extension on the end. If you have levers, contact me about substituting a lever latch which has stronger springs to reduce lever sagging. Weslock is no longer making thes latches, so face plate finishes are limited to Weslock's current supply. Review: Great product - Second time purchasing this item. Works great and is easy to install.

Works great and is easy to install. Wished it was available in more finishes ### ⭐⭐⭐⭐⭐ Great part *by W***N on February 19, 2026* Worked perfectly ### ⭐⭐⭐⭐ This part is a required replacement for a Weslock door knob latch. Series 600 *by R***R on October 8, 2023* Sometimes, in general, this part fails… I’ve replaced this part 3-4 times over the two decades I’ve owned my house to fix failing multiple entry door knob locking mechanisms (front door, garage to house entry and side garage doors). When the part does fail, you may not able to exit your door, which happened to me this time… which I describe the problem as being “not having the latch clear where it slides into the door frame despite turning the knob”, because the latch gets hung up in the door frame. No amount of cleaning, oiling will get it to retract any further… a mechanism within the cylinder just… breaks; door knob turns, door cannot open because the latch itself is still engaged in the frame. The part seems to present as failing or failed, requiring replacement, and can do so over time. That failure presents two ways: 1). The door does not stay shut when closed (latch doesn’t move into the frame completely when the door knob is released and the door is in “closed” position; and 2). A lip of the latch doesn’t retract all the way when the door knob is rotated open, so the latch itself remains slightly exposed enough to not allow the door to swing open. With a normal functioning part, the catch retracts completely into it’s cylinder showing none of the latch, this as the end of the cylinder is pushed (by the knob turning mechanism… or your finger once the latch is removed from the door, by plunging the end to retract the latch into the cylinder. I’ve had both circumstances happen, but this time my door lock failed one fell swoop, requiring me to use a multitool saw tip to cut the existing latch stuck out between the door frame trim and the door. Cutting the latch as such give me access to begin re-install this newly purchased part. So - long winded, original parts of twenty years ago lasted for about 7-10 years with moderate use. More recently, these parts seems to last less.. or for fewer years/uses. Old parts also used to come with new screw hardware (two screws) it seems; these generic ones don’t so screws need to be reused or purchased separately. Specifically to this particular part, I believe it’s generic, looks like the cylinder is held together w/ a screw in lieu of an original type rivet keeping the internal parts together. Does this imply better (rebuildable?) or just ease of manufacture? I don’t know but it shouldn’t matter as the design function function is the same. Going to install it now (an old temporary cylinder that was failing was being used until this came in…). Also of note: from the sellers description, the Series 600 is used in multiple lock models, even across multiple brands: I’m not privy to any of that info… I’m just a home owner whose done a couple of his own repairs utilizing this particular mechanism, for all it’s worth. Hope it works as per usual and hope this long narrative helps some home self-repair person out there encountering the issues mentioned above. I had to figure this out years ago pre-Youtube. Finally, I’m not a professional… this was my anecdotal experience. Your miles may vary. Proceed on your own laurels and do your research before deciding to fix your own things. 🙂👍 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/565273314-12721-600-series-dead-latch-compatible-with-weslock-latches-marked](https://www.desertcart.com.ar/products/565273314-12721-600-series-dead-latch-compatible-with-weslock-latches-marked) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-02*
