Advantage: The balancer features a solid metal construction with high load-bearing capacity. It effectively balances the weight of tools, reduces operator strain, supports sustained repetitive tasks, and enhances work efficiency. Instruction: The spring balancer allows tension adjustment via a knob. Turn counterclockwise to increase tension and clockwise to decrease tension. Application: Retractable spring balancers are designed to support and balance tools or equipment, allowing users to handle them without feeling their full weight.
