Torque Activated Core Chucks

Self-expanding and self-blocking Torque Activated Core Chucks engage the core as a result of the reel’s rolling action making it ideal for light or heavy continuous duty shaftless unwind or rewind applications. D-TA Core Chucks are also available with Modular Adapters when working with multiple core sizes up to 12″.
