Good fit
Holes aligned well with my frame. Took off one star because the anodizing had a minor scratch, but functionality is perfect.

Essential for CNC
High quality aluminum that feels durable. The open design makes assembly much faster than closed blocks.

Sturdy Mounts
Used these for a linear motion project. The machining quality is excellent and the shafts slide in smoothly without too much play.
