of high quality alloy steel, hot bent to shape using dies
and then heat treated under controlled temp / time cycles
for consistent spring characteristics. Collars are of
widened design for greater frame strength and to prevent
bows hitting casing. Integral hinges are designed to wrap
to the inside and are with eight sections and seven shear
points for minimum disorientation even under severe stress.
Hinge locking pins are of high strength steel for maximum
structural strength.
Bows can be configured for any hole dia from choice of
