Shop Stauff Unistrut Tube Clamps
Stauff Unistrut Tube Clamps provide a reliable solution for securing tubes within a system, ensuring a clean, organized layout while reducing vibration and noise. These clamps are designed to be mounted onto Unistrut framing, allowing for flexible and stable support in a variety of applications. Their vibration- and noise-reducing properties also contribute to environmental protection by minimizing sound pollution. When selecting the right clamp, it's important to verify the outer diameter (OD) of your tube, as tubes are typically measured by outer diameter. The "Nominal pipe/tube size" refers to the compatible tube size, while the "bore" is the diameter of the hole in the insert. Stauff's heavy-duty Unistrut clamps offer superior load capacity and durability compared to standard clamps, making them ideal for more demanding systems. If you're unsure about sizing, our team is available to help.
Pipe is typically called out by inner diameter size and tube is typically measured by outer diameter size.
Be sure to verify the OD of your pipe or tube prior to ordering.
