Blocks on focuser

[Robindonne]

I have a question about a crayford focuser that has 2 big rectangular blocks on top.  Im not yet planning to open them to see whats underneath it, but maybe someone recognize it?   My guess is the bearing but i Thought i sometimes see these blocks used as a clamp for finders or something like that.

Yes. Its the bearing. Have to dive in some old threads here and there before just asking😬.   Still learning.
