RTSH-PUC: Single Pipe Support
This Single Cross Brace Duct Support features H-Stand design and our non-penetrating, round rubber PUC bases, and provides perfect support for either roof ducts or cable trays.
The RTSH-PUC, Single H-Stand Duct Support safely and securely mounts spiral or rectangular duct on rooftops and is designed to maximize jobsite efficiency. Non-penetrating rubber PUC bases eliminate the need for prefabrication or on-site work, while protecting your roof. A welded cross brace and precut framing reduce hardware needs and allow for easy adjustability from 12” to 36”.
Bolt down bases are NOT interchangeable to address any seismic or wind concerns. See RTSH: Single Duct Supports if these concerns are present.
Available finishes: Pre-galvanized, Hot Dip Galvanized, and Stainless Steel.
