The RTSH-D, Double H-Stand Duct Support safely and securely mounts spiral or rectangular duct on rooftops and is designed to maximize jobsite efficiency. Non-penetrating RTSF21 rubber bases eliminate the need for prefabrication or on-site work, while protecting your roof. Welded cross braces and precut framing reduce hardware needs and allow for easy adjustability above 12”.  

Bolt down bases are interchangeable in most configurations to address any seismic or wind concerns that may be present.

Available finishes: Pre-galvanized, Hot Dip Galvanized, and Stainless Steel.
