RedHeader RO Rough Opening System is specifically designed for interior and exterior framing applications around non-load bearing doors and windows. The adjustable Drop’N Lock clip makes field adjustments easy and provides a flat surface for a smooth drywall finish. By using single members rather than a conventional built-up header or jamb system, the system significantly reduces material pieces and requires less maintenance. RedHeader RO contains pre- and post-consumer recycled content and is energy efficient. ClarkDietrich products can quality for up to seven LEED credits, and have an average recycled content of 48 percent.
