A 1″ wide stainless steel spring for Large and XL Saffire hinges (please note, some of our older XL hinges used our Ultra Torsion hinge spring), made of 8 AWG, or 1/8″ diameter, wire. The spring has 12 coils, with a 2.5″ distance between the furthest inner bend of each hook, while no tension is applied. The distance across the coils themselves is 1 and 11/16″, with no tension.
For reference, the distance between the posts for the dome and the posts for the base of our Large and XL hinges is 4 3/8″.
