This Macklanburg-Duncan high density foam tape is an inexpensive weatherstripping for use on door jambs and on the bottom of window sashes. It offers minimal compression to help insure a weathertight seal. To install, unroll the foam tape and apply to a clean and dry surface when the temperature is over 40 degrees Fahrenheit. Press in place, trim to length with a utility knife or scissors, and peel off the paper backing. The color is gray.
