An improved strut spring compression tool is provided having a load screw that extends between pairs of arms that are engaged with spaced coils of a strut spring to be compressed. The improved load screw is provided with a stop block formed unitarily thereon. The stop block serves as a limit stop that prevents further adjustment of the arms of the spring compression tool toward each other that could potentially result in damage to the component parts of the strut spring compression tool.

Why it's free to use
- Filed December 23, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 23, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 23, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
