Our Rope Door and Window Caulk is an effective alternative to tube caulking for both doors and windows. Unlike tube caulking, there is no caulk gun needed or messy cleanup when using rope caulk. Simply separate a strand of rope caulk and press the self-stick caulk into place. This caulk helps seal out drafts in small gaps, providing an easy caulking solution that will not harden or dry out.
