Closed Coil Spring System

Closed coil springs are available in 9mm and 12mm passive lengths and available in 5 force values – Feather Light (50g), Extra Light (100g), Light (150g), Medium (200g), and Heavy (250g).

The unique G4™ Nickel Titanium alloy developed by G&H® is precision formed into closed coil springs. G4™ Springs provide consistent force and remain active until the space is closed. Consistent force values and full recovery are both routinely achieved with G4™ NiTi springs – and also G4™ NiTi Archwires.

Step 1. Use the specially designed Ruler to measure the distance between hooks. (Fig. A)

Step 2. Flip the ruler over to view recommended spring for the 150g force range or refer to the Force Chart and select any force level and size spring desired.

Step 3. Match the spring size desired to the label on the box and engage spring (Fig. B).
