Position two lines side by side on rails and make quick adjustments, all without reaching for tools. Secure these clamps using the included rail nuts, then reposition them as needed—no disassembly required. They’re often used in modular production lines to make fast, frequent line changes. All fit tightly around pressurized lines in hydraulic systems to reduce vibration and cut down on noise. They are not compatible with strut channel or strut-mount clamps.
