Shop Stauff Unistrut Pipe Clamps
Stauff Unistrut Pipe Clamps are designed to securely hold pipes within a system, offering a clean and organized layout while reducing vibration and noise. These clamps are mounted onto Unistrut metal framing, providing a stable and flexible way to support pipes and hoses. Their vibration- and noise-reducing features also help contribute to environmental protection by minimizing sound pollution. When selecting the right clamp, it's important to verify the outer diameter (OD) of your pipe, as pipes are measured by inner diameter while tubes are measured by outer diameter. The "Nominal pipe/tube size" refers to the pipe size that fits the clamp, while the "bore" is the diameter of the hole in the insert. Stauff's heavy-duty Unistrut clamps offer increased load capacity and durability compared to standard clamps, making them suitable for more demanding applications. If you're unsure about the sizing, our team is happy to assist.
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.
