The spring repair block is used to temporarily repair your torsion springs to allow you to continue using your doors until a new set of replacement springs can be installed.
Your door is a heavy item, and opening and closing it without the torsion springs can be very difficult. The spring repair block will get your door operating properly without having to remove and replace the springs. Please note this is a temporary fix that allows you the time to research and identify the correct springs you need.
We also suggest that you purchase the torsion spring winding bars to safely re-tension the torsion springs.
