6 Pcs Extension Springs 3/8" x 6-1/2", 0.047" Steel Dual Hook

High quality

I used these springs to replace bungy cords holding tarps on both ends of my pole batn. Every few weeks I had to change bungy cords as they would sun rot and break from over use. I use these springs now in place of the bungy cords and have't the need to change them anymore unless they rust, which should take a great length of time.

Good quality and great value

Worked for what I needed them for. Good quality spring

The springs are decently springy. Seems to be made of standard material. They are quite long as well. They are not very strong though. They can be stretched out completely by hand and do not create much tension. So the overall spring construction is rather thin. I believe these would work well in light duty applications like for a storm door. Would not count on them being able to handle any item over 10lbs or so.

I bought these springs for an old drafting lamp. I've had this map for like 20 years and don't really want to get rid of it, but the springs are all worn out. I've been using rubber bands to bolster the springs, but that's janky and the bands snap after they dry out. I finally found some springs that fit. They took a little work to get on because they're nice and tight, but once I did, the lamp's swing arm feels brand new, lots of smooth articulation.

Well, they were a bit smaller than I realized, but they are good for what they are.

Bought them for a blast room, very happy with purchase
