REFER TO ERECTION DRAWINGS FOR PART CALL OUTS CAUTION

All trapezoidal panels are extremely difficult to install at hips and valleys in a weather tight manner. The use of these details should only be attempted by installation crews that are highly experienced. In order to help ensure weather tightness, Chief Building's recommends it’s MVF / MVP standing seam system for use on roofs that require hips and valleys.
