Forma-CL Universal Closure

Our Forma-CL is a specially engineered hybrid foam sealer that conforms to most shapes, creating a water seal at over 50% compression. Forma CL provides excellent compressibility with rapid recovery to fill gaps. The UV resistance properties ensures the foam will not dry out and become hard and brittle. The material comes with a custom adhesive backing, which is easy to apply and handle during installation.
