PivotTrue® coil hook springs are stress relieved 301 stainless steel, AAMA 902-07 certified, and available in 3/8", 1/2", and 3/4" widths in tandem and standard form. The patented full width hook lets the spring assemble to the shoe without fasteners.

Extra long tails allow triple spring balances with minimal assembly time and inventory. The matching one-piece dove-tail holders stack up to four springs in a straight, low friction stack and identify the spring size on the face of the holder; different sizes stack together.
