The M-D Cinch Aluminum and Vinyl Self-adhesive Top and Sides Door Seal Kit protects against drafts, moisture, dust and insects. Save on energy by sealing the top and sides of your door and keeping the heat or air conditioning from escaping. Cinch products are the easiest to install since they do not require hardware. This kit comes with three pieces, two 84" pieces for the vertical sides of the door frame, and one 36" piece for the top of the door frame. Before installation, cut to desired length using a hacksaw and be sure the vinyl bulb is compressed against the door to create a proper seal. Simply peel the liner and stick to the door frame.
