Turnbuckles are in the group Cable & Wire Rope Fittings. Wire ropes and cables usually consist of groups of smaller wires twisted together as strands. Larger diameters are generally referred to as wire ropes, and smaller diameters as cables. Wire rope and cable fittings include clips, sleeves, ferrules, and other hardware used to construct assemblies so they can be used for applications involving tension.
Turnbuckles are available on the FCH Network with Imperial/US diameters that range from #1 to 2 and with Metric diameters that range from M4 to M48.
