Welded cross braces and precut framing reduce hardware needs and allow for easy adjustability above 12”.

All H-Stands are compatible with 1-5/8” channel accessories. Pipe clamps, rollers, clevis assemblies, and pipe shields can be attached to meet the needs of any project.

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