Southwire Side Tray Clamp (STC) – Side-Rail Mounting for Maximum Roller Flexibility The Southwire Side Tray Clamp (STC) offers a fast, tool-free solution for mounting box rollers like the HB1A-9 Universal Split Box Roller and HB9A Open-Top Box Roller directly to the side of any cable tray. Designed to secure to the tray’s side rails—the strongest structural point—it provides added support exactly where it’s needed along the cable run. The STC accommodates any tray depth and allows rollers to be mounted upright or rotated 90 degrees to handle top, bottom, or side cable loads using heavy-duty rollers. With a tight, reliable hold and quick installation, the STC delivers unmatched flexibility and strength in the field.
