Century Spring 4002 Swing Extension Springs (2-Pack) - Heavy Duty Garage Door Replacement Parts for Smooth Operation

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.
