The MSI Dyna-Clamp is a reliable and rugged digital tension meter engineered to accurately measure the tension of wire ropes used in lifting, rigging, and cable-safety applications. This handheld device is built for field use and features a dual-line LCD display that ensures visibility even under harsh sunlight.
Ideal for professionals needing to verify load tension, the Dyna-Clamp supports up to 1-inch wire rope diameters without any mechanical adjustments. Its live tension readings are displayed prominently, while the second line on the LCD can be configured to show peak or average tension, or rope diameter—enhancing usability and real-time insights.
Durability is at the forefront of the Dyna-Clamp's design. Its IP65-rated anodized aluminum frame withstands tough environments, while its scratch-resistant screen overlay protects against jobsite wear and tear.
The unit comes preloaded with up to eight factory calibrations, eliminating the need for recalibration between common wire rope types—helping to reduce downtime and improve accuracy. Plus, with OSHA-compliant safety strap capability, it's the safe and smart choice for critical tension verification tasks.
