Abstract
A side rail assembly for a wheeled carriage includes side rail posts secured by a support structure including bushings having inner flat sides that expand outwardly to adjust for variations in the tolerance of the side rail posts and snugly secure the side rail posts to the support structure. Such variations can be caused by a finished surface applied to the entire outer circumference of the side rail posts and the support structure to improve the appearance thereof. The support structure enables curved side rail posts to rotate about their axis at lower ends thereof.
