U Channel Rubber – Universal for Rear Quarter & Back Windows This U channel rubber is a universal fit for rear quarter and back windows, ideal for hot rods, customs, and many other builds. Designed for a traditional look with superior flexibility, it conforms easily around tight corners and seals cleanly against the body. We use this profile regularly on fibreglass hot rods, especially 5-window coupes and Model A restorations. Its high-rubber content keeps it soft, pliable, and free from that shiny “plastic” appearance. The downward-angled flap applies pressure against the body for a snug fit — a small bead of sealant in the corner ensures a watertight seal. Base width: 14 mm Depth: 14 mm (to underside of flap) Suits 5 mm–6 mm glass Sold per metre – enter the total length required Industry reference: Part No. 220.006 .
