The slip-in cap design saves time on vent stacks where a hose-clamp counterflashing would otherwise be used; check the FlashCap drawing and product data sheet for exact pipe diameter ranges. Order TPO variants for TPO membranes and the PVC version for PVC roofs. The white cap can be painted if the membrane is a darker color.

Work on single-ply roofs requires fall protection and awareness of hot-air welding equipment; consult the manufacturer’s drawing and PDS before installing.
