Shop Stauff Rail Mount Pipe Clamps
Standard Rail Mount Clamps for tube and pipe are designed to securely attach pipes and tubes to metal rails, providing a clean and organized system layout while minimizing vibration and noise. These clamps are easy to install and offer a stable connection, making them ideal for a variety of applications. When selecting the right clamp, it’s crucial to verify the outer diameter (OD) of your pipe or tube, as pipes are typically measured by inner diameter, while tubes are measured by outer diameter. The "Nominal pipe/tube size" corresponds to the compatible pipe or tube size, and the "bore" refers to the hole size in the clamp insert. Standard rail mount clamps are suitable for general installations, while heavy-duty clamps are designed for more demanding systems, offering increased load capacity and enhanced durability for tougher environments. If you're unsure about the right size or type of clamp, our team is here 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.
