45mm x 765mm Galvanised Slipper Spring

6mm Galvanised Slipper Spring

6mm galvanised slipper springs are measured 765mm eye to the tip of the slipper leaf.

This spring style has the traditional eye and a tail that slides in a keeper or hanger.

Spring fatigue will stretch springs beyond 765mm in length.

Important Measurements

• Length
• Spring Thickness
• The number of leaves.

Dacromet or Galvanised

The choice between Dacromet springs and Galvanised springs is not tricky. Dacromet springs vary significantly in quality.

As a result, Couplemate prefers Galvanised springs to last longer than most Dacroment coated springs.
