KOOL KAP condenser covers use a unique design that tilts the cover up automatically whenever the condenser fan operates. Gravity gently drops the Kap down to its horizontal position once the system turns off. The interior cabinet and components are protected from dirt, leaves, debris, and weather. This patented design forever eliminates the need to cover and uncover condensers for seasonal protection. Kool Kaps are permanently installed, without tools, in just minutes. Kool Kap condenser covers come in three sizes, which permit proper fit on virtually any make or model of air conditioner. Visit www.koolkap.com or call 800/878-6614.
