SCHB Bad size and incorrect profile
Silver 10PCS - 1220 mm
- The extrusion's external dimensions are undersized (19.8mm, not 20mm).
- More importantly, it's v-slots are oversized, meaning that 2020 carriages are unable to ride along the extrusion making it useless for this purpose.
- Furthermore, the groove is not a v-shape as is advertised, but a step shape that causes further issues.
Would only possibly suit structural uses where the dimensions are unimportant and no carriages are being used.
