I have 7 composite shutters that will fit an opening of approx. 57 1/2" - 59" wide by 70 1/2" - 71 1/4" tall! T-posts were made approx 1 1/2" off center but its not obvious unless you open the shutter doors. Original cost about $650 ea..Available for $50 ea if you buy all 7 or $75 ea if less than 7 are needed! They are 4 panel units with a beautiful deco frame on 3 sides and a flat sill,plate for the bottom.
