GRANDVIEW, Missouri — Ruskin has relaunched its patented XP500 aluminum extreme weather louver with a new, low leak flange mounting option. The new flange frame XP500 provides the same high performance as the standard model with easier installation and streamlined shipping. “The new flange frame option for Ruskin XP500 louvers is a direct result of customer feedback,” said Andrew Jones, product manager for louvers at Ruskin. “Designed for direct mounting of the flange to the substrate, the new installation option eliminates the need for — and shipping of — mounting parts like clip angles.”
