A drainage track useful in combination with exterior insulation and finish systems including a clog-resistant drainage channel so that water collecting behind the exterior insulation and finish may drain from the structure. The drainage track, in a preferred form, is extruded from PVC and defines a substantially L-shaped configuration in cross-section. An elongated, relatively tall flashing leg is provided for attachment of the drainage track to the structure such that all water resistant material and insulation laps over the flashing leg to direct water into the drainage channel. Finish apertures are provided through a portion of the drainage track so that exterior finish such as, for example, stucco, will readily adhere and bond to the drainage track.
