Jaw and jaw turnbuckle – frequently asked questions
What is a jaw and jaw turnbuckle?
A jaw and jaw turnbuckle has a forged jaw (clevis) with bolt, nut and cotter pin at both ends, joined by an open body with right- and left-hand threads. Turning the body adjusts the tension of wire ropes, guy wires and lashings.
What is the safety factor of a CAPVINA hot-dip galvanized turnbuckle?
CAPVINA turnbuckles are made to ASTM F1145 with a 5:1 safety factor: minimum breaking load = 5 × working load limit and proof load = 2.5 × WLL. Every batch is magnetic-particle inspected with no cracks allowed.
Which ASTM F1145 turnbuckle sizes are in stock in Vietnam?
CAPVINA stocks 11 sizes: 1/2″×12″, 5/8″×12″, 3/4″×18″, 7/8″×18″, 1″×18″, 1-1/4″×18″, 1-1/2″×18″, 1-3/4″×24″, 2″×24″, 2-1/2″×24″ and 2-3/4″×24″ – working load 1 to 34 tonnes. Other sizes from the 28-size catalogue on request.
How do I choose the right turnbuckle size?
