you probably just purchased 20-2020 (metric) series t-slot from 80/20.



I don't know what the one on the right is, but it looks a little different than 1010 (standard) series t-slot from 80/20, you might need to investigate where your previous t-slot came from?

Based on their photo, it's more like that they have 25mm 80/20 extrusion:

1 inch = 25.4mm, so that would likely explain a ~0.5mm measured difference.

Both items in the photo show the metric-style hole pattern in the center of the piece.

I don't think those pieces came from the same manufacturer. Is that a possibility?

We ordered them both from 80/20. I will take exact measurements and get better pictures in an hour and a half.

These are all different extrusions that 80/20 offers.

Yeah, and the only other one that has the same hole pattern is the 3030, interesting.

the OP is calling what they just got 2020, which is why I make the assumption they have 80/20's 20-2020 series.

80/20's 25-2525 actually claims to have a slot max width difference of only about 1um from the 1010 series:

is 80/20 trying to slowly trick us ('Murica) into giving up our fractions??

Metric is awesome.

In reality, by using inches you are indirectly using metric. Inches are actually defined by law as a derived metric measurement.

agreed. i forgot to add the vb code to that one:
