Abstract

An end dam for a generally U-shaped moisture management channel comprising: a vertical wall having a front and a rear surface and a base edge; a first flange extending at a right angle from the rear surface in the area of the vertical wall base edge, integrally formed therewith, and having a distal edge and a base edge; and a second flange having a base edge extending from and integrally formed with the rear wall, spaced apart from the first flange and extending angularly away from the rear surface toward said first flange distal edge to define a slot between the first and second flanges. The first and second flanges of the end dam frictionally engage the base or bottom of a generally U-shaped moisture management channel causing the vertical wall to abut the sidewalls of such a device.
