The Norbar 181446 Compact Series Hand Torque Multiplier with Anti Wind-Up Ratchet and Cranked Reaction, 1” Square Drive is designed to deliver high-output torque in a package that is easier to position, handle, and control. Their compact dimensions provide excellent access to restricted applications, while the lightweight design for their torque capacity improves portability and reduces operator strain during setup and use. Despite their manageable size, the range covers maximum output torque up to 7,000 Nm, making them suitable for demanding industrial fastening tasks where standard hand tools cannot generate sufficient torque.

A key safety and usability feature is the robust 48-tooth Anti Wind-Up Ratchet (AWUR), which contains the forces generated during tightening for safer, easier operation. This helps reduce uncontrolled spring-back and improves operator confidence when working on high-torque joints. Each unit is supplied as standard with a steel reaction arm, while additional reaction optionsincluding customized reactionsare available on request to suit specialist access requirements and joint configurations. With 4% accuracy, the Norbar 181446 Compact Series Hand Torque Multiplier with Anti Wind-Up Ratchet and Cranked Reaction, 1” Square Drive supports dependable torque application in critical jobs. Every multiplier is supplied with its own unique traceable calibration certificate, allowing accurate calculation of input torque for quality-controlled applications. Made in the UK, it reflects Norbars commitment to durable, precision-engineered torque solutions.

The Norbar 181446 Compact Series Hand Torque Multiplier with Anti Wind-Up Ratchet and Cranked Reaction, 1” Square Drive is ideal for heavy maintenance, utilities, rail, energy, offshore, and industrial shutdown work where high torque, tight access, and safe manual control are all essential. They perform especially well on large flanges, structural fasteners, and machinery joints where accurate high-torque tightening must be achieved in confined or awkward tool environments.
