Prime-Line SP 9667 Extension Spring, Spring Steel Construction, Nickel-Plated Finish, 0.047 GA x 7/16 In. x 3-1/2 In., Closed Single Loop (2 Pack)

Right spring strength, right length. All good

I needed the springs to stretch and retract without losing their recoil and they performed excellent. The wire diameter of .046 held up well for my application.

Perfect fit!

I used these along with binder clips to make water bottle holders for my pets when traveling by air a long distance. They were the perfect length and very strong and flexible. I also use them to keep the door of the pet carrier and the cage open when I don't want it swinging closed on little tails or toes. A must- have for small pet owners.

Good value for the price including a two pack of springs.

This spring works exactly as you would expect, has great tension, and it is nice that it comes in a two-pack for a very reasonable price. I don't expect to need to buy a new one for quite a long time even with regular use.

These springs was exactly what we need to get the job done!

Used as a tensioning spring in a cajon for the snare adjustment and worked very well, ends are closed loops like a key chain ring so won’t detach easily but can be removed if required.
