12721 600 Series Dead Latch Compatible with Weslock latches Marked 600 Series, Adjustable Backset with Radius Corner Nickel Face Plate

Second time purchasing this item. Works great and is easy to install. Wished it was available in more finishes

Worked perfectly

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. 🙂👍

Most efficient purchase ever. We bought a house and our door lock wasn’t working properly. We reached out to Cindy from Williams Parts Company and sent pictures of the door knob and she immediately knew which latch I needed. I was impressed by the speed of response and expertise!
