Endura’s Simple Solution™ Corner Pad I is an essential piece to your door unit. Creating the perfect seal is crucial for blocking out air and water infiltration and decreasing your home’s energy efficiency. While small in size, the Simple Solution™ Corner Pad is big in performance. This design works to counteract upward water pressure within the weatherstrip instead of fighting against it. The sealing lobe presses against the weatherstrip around your door frame for a double layer of protection against air and water leaks and seals in your temperature-controlled interior. The Simple Solution™ Corner Pad is easy-to-install in just a few short minutes, with no tools required!
