We loved the idea of barn doors and figured we'd have to cut support bar to fit our tiki bar BUT we also trusted the directions to give correct measurements.  They didn't.  You really need to know how to measure and cut properly or your doors will be off.  Directions on cover give one measurement and say they are wrong so look inside at the instructions.  The instructions give same measurement number.  Happily my husband is a wiz at anything and it is a great look.
