Henderson Dolphin green replacement spring (Single)

When replacing springs we recommended that both sides are replaced at the same time as it can be difficult to ensure that the spring tension and garage door are balanced correctly.

Commonly used on double Dolphin (12'6" to 14'6" wide) and Doric tracked (8'0" to 9'0" wide)

Available with or without the APZ 140 Adjuster Bolt (See product options).
