End fittings are Quenched and
Tempered, bodies heat treated by normalizing.
Turnbuckle eyes are forged
elongated, by design, to maximize easy attachment in system and minimize stress
in the eye. For turnbuckle sizes 1/4″ through 2-1/2″, a shackle one size
smaller can be reeved through eye.
Modified UNJ thread on end
fittings for improved fatigue properties. Body has UNC threads.
Crosby products meet or exceed all the requirements of ASME B30.26
including identification, ductility, design factor, proof load and temperature
requirements. Importantly, Crosby products meet other critical
performance requirements including fatigue life, impact properties and material
traceability, not addressed by ASME B30.26.
TURNBUCKLES RECOMMENDED FOR STRAIGHT OR IN-LINE PULL ONLY.
Lock Nuts available for all
sizes
Comprehensive end fitting
data available
Fatigue Rated.
Meets the
performance requirements of Federal
Specifications FF-T-791b, Type 1 Form 1 – CLASS 4, and ASTM F-1145, except
for those provisions required of the contractor.
