Mortite 45-ft. Gray Caulking Cord

Mortite Rope Caulk is a weatherstrip and caulking putty in a roll. It can be applied around the edges of windows to reduce uncontrolled air infiltration and ex-filtration, 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 45 linear feet of caulking cord, which is generally suitable for sealing 3 average-sized windows.
