### ⭐⭐⭐⭐⭐ Compression spring to make a great swing
*by C***H on December 3, 2019*

I installed a wooden porch screen and wanted a set of springs to relieve pressure and be more comfortable when sitting on the swing. But, I did not want stretch springs because these can fail with too heavy of a weight. This is where the compression spring works great. It does bottom out with a high weight, but that is part of the design. It is easy to install but you do have to be able to pinch the shuttles of the spring together to push them through the spring when installing. You may need to look it up online to see what I'm describing. It's not hard. It just takes a small amount of effort. Make sure you measure the length of the spring and add this length into the calculation when you are getting your chain length measured for your swing. I also recommend that you find a rafter or ceiling stud and install the eye bolt directly to the stud. The spring would then attach to the eye bolt. The springs work great and the swing is comfortable to sit on.

Works great

### ⭐⭐⭐⭐⭐ Durable and comfortable
*by C***E on December 8, 2012*

These springs add a very nice cushion when sitting down on the swing. The ones I received were rated (printed on package) for 300lb each spring NOT 325lb as stated in Amazon description. They were the 4002 model too. Not a big deal for us, can seat my entire family on a set of these! I have had about 550lb of people on the swing before, and it's about a 100lb 5ft cedar swing. Their obviously wasnt any additional spring slack or cushioning at that weight, but they held up fine. They're rated much higher then the best swing hook lags I could find at home depot when I initially installed (200lb per hook). The springs here were also much cheaper then the only pair there.
