Mortite Rope Caulk is putty in a roll. It can be applied around the edges of windows to reduce uncontrolled air infiltration and exfiltration, help reduce moisture condensation, and to seal against dust, dirt, and insects. It is installed by simply pressing it into place with your fingers. Easily applied, self adhering, yet easy to remove. Rope caulk is an especially good option for apartment residents. One roll consists of 90 linear feet of caulking cord, which is generally suitable for sealing 6 average-sized windows. It is available in either a gray or brown color.

Note: This is a non-returnable item.
