The painted tip shows the weight rating for your spring. Because colors repeat every 100 pounds, always confirm with the actual door weight or measurements rather than color alone.
Common extension spring color codes:
- Blue: 40 lb, 140 lb, 240 lb
- Red: 50 lb, 150 lb, 250 lb
- Brown: 60 lb, 160 lb, 260 lb
- Orange: 70 lb, 170 lb, 270 lb
- Gold: 80 lb, 180 lb, 280 lb
- Light Blue: 90 lb, 190 lb, 290 lb
- Tan: 100 lb, 200 lb, 300 lb
- White: 110 lb, 210 lb, 310 lb
- Green: 120 lb, 220 lb, 320 lb
- Yellow: 130 lb, 230 lb, 330 lb
Example: A gold tip could indicate 80 lb, 180 lb, or 280 lb depending on door height. Always cross-check with door weight.
