Shop Stauff Heavy Rail Mount Tube Clamps
Stauff Heavy Rail Mount Tube Clamps are designed for secure and efficient installation of pipes and hoses, ensuring a clean, organized system layout. These clamps are engineered to reduce vibration and noise, contributing to improved environmental protection. They are mounted on a rail system for easy installation and stability. When choosing the right clamp, it's essential to measure the outer diameter (OD) of tubes and the inner diameter of pipes, as pipe sizes are usually specified by inner diameter, while tube sizes are specified by outer diameter. The "Nominal pipe/tube size" refers to the size of the pipe or tube the clamp is intended to hold, while the "bore" is the diameter of the hole in the insert. Heavy rail mount clamps are built for higher load capacities and more demanding applications compared to standard clamps, offering enhanced durability and support for larger, heavier systems. If you're unsure about the right size, we're happy to assist in making the correct selection.
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.
