LM Rail

Other manufacturers are dimensionally compatible to THK, so does it have to be theirs?

Well I've got THK blocks and assumed that I would need thier rails, but if thats not the case all the better.

Unfortunately not - each manufacturer's blocks will only work with their own rails. I meant that the hole layout and external dimensions are generally compatible.
