The metal leg slides on, and in the measurements was purposely made slightly loose to allow it to be adjusted into both a table and a carrying basket. This leg design has the potential to be manufactured in certain standardized sizes, and would allow the buyer to slide them on to just about any material they could want within the size limit. This is a fun opportunity for people to customize their own space with a characteristic piece of wood they have, a funky sheet of metal, the possibilities are endless!
