Features

• Military specification spring steel - SiCr – the best possible steel for springs
• Progressive coiling – Providing a soft start which eases stress on both mechanical and electrical parts
• Closed and ground ends - Stable straight ends minimizes side bending improves performance
• Pre-compressed - Greatly reduces power loss from initial shrinkage Black zinc plating - Corrosion protection which does not impair spring performance
• Color coding for easy indication of individual spring grade
