ABSTRACT:
A snap-in metal strip, longitudinally bent into a V shape with the upper ends of both arms of the V being turned outward to the horizontal, thus creating longitudinal lips on the strip, is used to seal an elongate gap, for example a narrow space between adjacent, closed blades in a louver damper. The strip is releasably held on one side of the gap by means of two, opposed, crevice-like channels into which the lips of the strip fit.
