From product fields [S1].
A tube that is slightly out of round may need the next adapter size. Re-check tightness after the first week of use.
By tube size: casters for 1-1/2 in ID tube. Kits only: expanding rubber adapter kits.
Tightening the bolt squeezes the rubber adapter so it expands and grips the inside of the tube.
Round tube with an inside diameter from 3/4 to 1-7/8 in, plus some square tube sizes.
210 to 350 lb per caster, depending on wheel.
