Vad heter namnet på den här gjutmetallen i mitt lockset?

Från surfing lite verkar det som om Baldwin har en mängd handtag som arbetar med ett begränsat antal låsuppsättningar. Om du inte bara kan köpa plåten behöver du bara köpa låssetet.

Det verkar kallas en "Landing Plate"

We’ve had two Baldwin handle sets fail on our new front door in the past six months, and I finally figured out why the manfacturer included a second landing plate with the set.

Basically they must have known it would fail prematurely.

The thumb latch is a lever that sits on a set of little pins set on a brass die casting, shown above, which allows it to toggle up and down. Unfortunately, brass die castings are about making things fast, and such parts typically have crappy structural performance and are prone to stress cracking.

What probably happened is that a tiny crack formed on one side of the casting and propagated every time we squeezed up and down on the handle. One side failed (red arrow) and our door handle starting twisting at an odd angle. Thankfully we replaced it with the second landing plate before we were locked out of the house.

After going through two sets, we bought a new set and discovered that designers finally figured out they needed to reinforce the casting for the load by reinforcing the area where the pin sets (right image).

Delnamnet är inte relevant vid denna tidpunkt, eftersom Baldwin har omstrukturerat delen. Om du har en äldre ring deras tech support och förklara problemet och de kommer att skicka dig ett konverteringspaket som löser problemet.
