Rack upright size
2x2 in rack uprights: size, hole sizes and pulley mounts
What 2x2 in means in millimeters, how it gets confused with 50 mm tubing, the hole sizes makers list for it, and which pulley mount lists 2x2 fit.
Also listed as 2x2 rack, 2 x 2 in tubing
Short answer
A 2x2 in upright is nominally 2 in per side, which is 50.8 mm calculated from 25.4 mm per inch. Fringe Sport lists its Sidewing Bottom Pulley for 2x2 tubing with 1 in or 5/8 in holes. Some sellers label 50 mm tubing as "2x2", so check the maker's millimeter size and measure your upright.

Watch out for
- Fringe's 2x2 fit is for its own pulley only; it does not mean every 2x2 rack fits.
- A 50 mm "2x2" is 0.8 mm narrower than a true 2 in upright (50.8 mm), calculated from 25.4 mm per inch.
- Hole size matters as much as tubing size: Fringe lists 1 in or 5/8 in holes for 2x2.
