IMPORTANT: We will always manufacture to the sizes you enter, so you must make any deductions yourself.
TOP TIP! Measure to the underside of the existing sill unless it is NOT going to be replaced. IE a concrete sill is present. If you do need a sill then enter the overall height measurement including the sill.
