Review on Performance Tool W84603 Door Spring by Tone Hatton

Item works. I'm not sure if it's strong enough to fully compress the pivot spring. Do this: Take the large C-clip and slightly tighten the spring, insert the spring tool and then compress the spring with the large C-clip. Hand-tighten the nut on the spring tool. When the spring is fully compressed, tighten the spring tool nut and remove the C-clamp. It takes less than 2 minutes. Reinstall the spring and use a wrench to loosen the spring tool nut.
