Product function Spring balancer with adjustable tension to support and balance the weight of a tool or load, keeping the tool suspended and easy to position. Key benefits Reduces operator fatigue by carrying the tool weight and minimizing the effort required to hold and move tools. Improves work consistency and efficiency in repetitive tasks by keeping tools at a stable, accessible position. Durable metal construction provides reliable load support and long-term service in workshop or production environments. Main features Adjustable tension control: turn the knob counterclockwise to increase the spring tension; turn the knob clockwise to decrease the spring tension. Solid metal structure with high load-bearing capacity for dependable balancing of tools and equipment. Simple, intuitive operation that lets operators quickly set the correct balance for different tool weights. Compatibility and performance Designed to balance a range of handheld tools and fixtures; tension can be tuned to match the tool weight for smooth vertical movement and quick positioning. Robust metal construction supports frequent, repetitive use and helps maintain consistent performance over time. Smooth retraction and extension behavior when correctly adjusted. Typical applications Assembly lines: hold and balance screwdrivers, riveters or other hand tools to speed up repetitive fastening work and reduce operator strain. Maintenance and repair stations: keep tools accessible and steady for technicians working on machinery or vehicles. Electronics or small-part production: balance light tools and fixtures to improve precision and reduce operator fatigue during repetitive tasks. Notes for use Adjust the spring tension using the rotary knob to match the exact weight of your tool for optimal balance and performance. Regularly inspect the mounting and metal components for wear if used in high-duty environments.
