DO NOT BUY THIS PRODUCT..EXTREEMLY HARD TO INSTALL..I HIRED VERY EXPERIENCED CARPENTER & HE HAD A HARD TIME FOR MANY REASONS I WONT GO INTO HERE. ALSO THE MATERIAL IS VERY CHEAP. PLASTIC FILM OVER BOARD. VERY HEAVY. LOOKS FAIRLY GOOD, THATS THE ONLY POSITIVE THING I HAVE TO SAY. HARD TO FIND MODERN LOOKING BI-FOLDS
