I have a support box that sits below the ceiling so need a collar to meet the ceiling (drywall) but am having a hard time finding just a square collar to attach to the support box or ceiling. Is it unusual to need to buy a collar by itself? Is there a more diy option to cover the area where the drywall and pipe meet?
