Hello,
My locking mechanism for our sliding glass door SDG5470 is starting feel like it's having signs of wear. The door is supplied by 84 lumber in Savannah to our home builder Pulte. I have attached a pic of the mechanism, there are 2 parts that come out and attach to the door latch. Is this something that you could supply? If you need more information, just let me know.
Thank you.
Vincent
Hey Vincent. Our 82-265 Mortise Lock looks awfully close, but how do the dimensions compare? Take a look below and let me know what you think. Note that the two teeth on this mortise lock point 'inwards'. I can't entirely tell if that's the case on your old lock, so please confirm. Also note that if this lock looks good for you, you might want to replace the keeper as well with the 82-249--we've had customers report that the 82-265 works best with this new keeper. Let me know if you have further questions.
There might just be play in the thumb lever due the mortise lock being broken. In fact, many customers mistakenly assume the thumb lever is what's broken for this very reason, without realizing the mortise lock is the chief culprit. That said, if you haven't already it is worth removing the handle set and inspecting it and the thumb lever for any sign of damage. If it seems broken, our 82-106 might work as a replacement--but look it over to confirm it matches your old thumb lever's design.
Finally--yes, lithium grease should work just fine as a lubricant. We often recommend silicone spray instead, since in theory it should attract less dust and dirt--but so long as you're not applying the grease too liberally, that shouldn't be an issue in my opinion. Let us know if you have any further questions, and Happy Thanksgiving!
