In parts 3 & 4, Craig demonstrated how he installed the field panels that intersect with the valley and prepped them to fit the formed valley piece. Next is the actual double seaming that will make the ridge and valley watertight. There is alot of seaming to be done when choosing this installation method. Manually hammering the lock with a Wedged PVC Hammer and a PVC Seaming Anvil as well as finishing the fold with the Biegetec 2 in 1 Combo seamer completes the seam.
