Spring fit perfectly and provides strong spring force needed.
This worked perfectly to fix my WORX WG191 string trimmer that lost the spring for dispensing the string. It is a tight fit the provides lots of force for the string advancement to work properly. Glad to have my string trimmer back up and running and not have to replace the whole machine.

Excellent
The spring is great - very durable and holds its shape even after a lot of compressive force. Just make sure you use the chart from the photos to get the right size.

It's a 2-Pack!
Usually happy to find out something ships in higher quantity than expected, but the ended up not fitting. So since I needed two and the super tiny 2-pack icon wasn't on the image for the size I bought I now have 4 springs that don't fit what I need them for. Them not fitting was a gamble, I needed them to fit over something that is 7/8" and they were just a touch too small. Maybe include inner diameter on the listing? Otherwise, they seem sturdy and I am trying the 1-1/8" to see if that will fit and only ordering qty 1 this time!

I use these in my cheese press. They make it easy to calculate pressure form 5lbs to 50lbs
