This durable, weather-resistant orange and yellow reflective cover fits virtually any size pitot tube. It stands out in daylight or darkness under all weather conditions, so it can't be missed. Large sewn-on Velcro tabs keep it securely in place under all conditions. The length of the tube must not exceed 6.75" and the diameter must not exceed 7/8". If it does, the Universal Pitot tube cover would be a better choice. The covers fit all Beechcraft, Cirrus, Diamond, and Grumman Mooney aircraft, most Cessnas and Pipers, and other aircraft equipped with angled pitot tubes. Reflective is 7.75" long.
