Full Description 

The introduction of BCI’s patented PolySeam® system creates a fast and cost-effective alternative to traditional batten bar attachments. Utilizing XR-5 or HDPE, the PolySeam® system replaces maintenance and repairs needed to maintain integrity of the batten bar method of attachment — for a virtually maintenance-free system. Installs faster and is more durable, saving thousands of dollars in installation costs, and it installs in the most extreme conditions.
