They do work. Just don't go by the diamension.
Hey they do work on the 20mmx20mm rail system. One thing is, someone might do a little diamension check. These are not 20cm (7.87") wide, height, and length. I know cm vs mm is a little confusing. 2cmx2cmx2cm or 20mmx20mmx20mm (and .32cm or 3.2mm for thickness) would be the correct rough diamensions.

Truly 20mm by 20mm
Perfect at 20mm x 20mm, not like similar ones that stick out a few mm. That means the hole at the end of a 2020 extrusion lines up. I bought twice now.
