Most boring question ever DIY

[Slazengerbag]

sorry for the boring question but I can’t think what they are called.

When you close a window and you push the latch down there is a black thing about 5cms square that the latch goes over to make a tight seal (am I making sense?) what are they called?

Can you take a picture of what you mean

The catch? The anchor plate? Either way I doubt you'd be able to buy it separately...

I found some. It’s a cockspur wedge!

I am not sure if I could go into a shop and keep a straight face while asking for that ( yes childish I know)

That is an amazing useful thing to know, you might win a pub quiz or Mastermind with that!
