WARNING: 

Torsion Springs are not a DIY product.  Installing Torsion Springs poses significant risks and should only be undertaken by a certified technician and those with appropriate tools.   Torsion Springs in conjunction with their accompanying hardware are under intense tension.  Tension must be carefully released from the springs before any work in undertaken.  Failure to do so or mishandling of the torsion springs can lead to severe injury or death.  

It is strongly advised that if your garage door has two springs that both springs are replaced even if one is in good condition as in most cases they have shared the same length of time, workload and metal fatigue.  

By purchasing this product, customers acknowledge and accept the inherent risks involved
