Developed with feedback from Diamond, the Plane Sights double-sided stall warning plug fits any Diamond DA40, DA50 and DA20, one way or the other. This composite-reinforced, ergonomic stall plug is the perfect all-weather, easy-in, easy-out way to prevent insects and ice from clogging your stall indicator and jeopardising the safety of you and your passengers. The blazing yellow colour of the firmly attached foot-long, ANSI-compliant and weather-resistant reflective remove-before-flight streamer stands out equally well in daylight or darkness under all weather conditions, so it can't be missed during your pre-flight inspection.
