Review: Perfect replacements - Exactly what we needed
Review: Heavy duty and strong - My sons trampoline started showing signs of stretched springs on one side. Found these and ordered a set. These are some nice springs that look to be of high quality and strength. They took some elbow grease to get them stretched back onto trampoline mat but once they were all on it looked good as new. Whats nice is that they offer various sizes for whatever tramp you have. Like with any metal over time they will eventually weather and may start to rust but these are so inexpensive, you can always change them as needed. I wouldn't hesitate to buy these again if needed.

### ⭐⭐⭐⭐⭐ Bought these as replacement springs for mini exercise trampoline
*by L***B on March 15, 2024*

Replaced a few broken or distressed springs and the tool worked well too fix them. Better than buying a new trampoline! When purchasing measure the entire spring, not just the coil part. I ordered the wrong size the first time.
