wire rope buckle free sample
Lexco® Cable carries a full line of cable turnbuckles for adjusting the tension or length of wire ropes and aircraft cables when they’re attached to structures, supports, or other cables or wire ropes. Turnbuckles are available with various end connectors, including hooks, eyes, and jaws. Threaded studs are also available. We stock both domestic (Made in the USA) turnbuckles and imported models.
We offer galvanized and stainless steel turnbuckles for various applications, such as marine and architectural, as well as midget turnbuckles for light-duty applications. Corresponding jam nuts are available upon request. For aerospace applications, we offer turnbuckle body MS21251, clevis MS21252, eye MS21254, eye MS21255, and turnbuckle locking clip MS21256.
Architectural and marine turnbuckles are stainless steel Type 316. Architectural turnbuckles for cable railing applications have close (pipe) bodies. Cable railing turnbuckles are typically machine swaged to the cable, but some models can be field installed via hand tool 53-215 or swageless models via wrench.
Imported forged, galvanized turnbuckles meet US Federal FF-T-791B specs; domestic-made forged, galvanized turnbuckles meet ASTM F1145-91 Type 1, Grade 1 specs.
All varieties of turnbuckle we stock are available in bulk quantities or as part of completed cable assemblies. Lexco specializes in cable assembly fabrication, to save our customers valuable time and money in production costs.
To view standard swaged turnbuckles, please visit ourArchitectural Cable Railing Components page. If you are looking for open body or closed body swageless turnbuckles, please see our Swageless Fittings page.
Note:There are three ways to specify the callout of the turnbuckles your application requires. Most common is, for example, 1/2 x 6, where “1/2” signifies the thread size, and “6” signifies the take up, or how much thread length is useable for adjustment. Instead of specifying take up, turnbuckles can also be specified by “open length,” where the turnbuckle ends are fully extended; or, “closed length,” where the ends are turned fully into the body.

Rope Services Direct supplies a variety of anti-spin non rotating wire rope (also called rotation resistant wire-rope). All standard rope wirehas a tendency to develop torque and therefore prone to rotation, whereas non-rotating wire ropes are designed so that the wire-rope outer rotational force naturally counteracts the inner strands rotational force. This is in the event that a rope is subjected to a load.
Rope elongation and rotation occurs on standard ropes when loaded, which can therefore spin the load, quite possibly out of control, which can be dangerous. When the rope rotates in this way the strands will begin to unravel. This causes the rope to lose strength and will undoubtedly fail, which could be catastrophic. It is for these reasons that non rotating wire rope is commonly used for many types of lifting applications including main hoist rope, whip rope,crane rope, off-shore and deck rope and more.
Non rotating wire rope or rotation resistant wire rope has a different construction to standard. as wires and strands are not laid in the same direction like they would be on standard rope. Inner and outer strands of wires are laid in opposite directions. For example the inner may be constructed in left hand lay whilst the outer layer is in right hand lay. The nature of this construction means that torsional forces on the inner and outer wires/strands will counteract each other and therefore minimising the risk of unraveling.
It is worth noting that the number of strand layers will have an effect of the resistance of rotation. A 2 layer rope has less resistance than a 3 layer rope. Therefore the more layers the rope has the greater rotation resistance it will have.
These types of ropes can be classified as spin resistant, rotation resistant or non rotation resistant. Classed on the basis of the number of rotations a certain length of rope does when a force of 20% of the MBF is applied; with 1 turn or less the rope will be classified as non rotating; with rotations between 1 & 4 the rope is classed as low rotation and for rotations between 4 & 10 the rope will be classified as spin resistant, any higher and the rope is NOT rotation resistant at all.
Correct usage and care with handling will prolong the working life. This is due to the friction on the inner wires caused by the strand crossover’s which will eventually cause the inner wires to break up. This is more apparent on non rotating wire rope with two layers. Ropes with 3 or more strand layers will distribute the radial pressures more evenly. Which will reduce friction and stress on the inner wires.
Regular,thorough inspectionsof non rotating rope are essential due to the fact that it is the inner strands that often break first and broken internal wires often go unnoticed as they are difficult to see.Rope Services Direct offer inspectionson all rope with certification issued on completion.
Holding both ends of the rope will prevent unraveling. Correctly fitted terminations will help to prevent damage. Kinking and unraveling may occur and they can also have an effect on the rotational balance if not fitted correctly.
Wire rope thimbles also known as cable thimbles, are used for making reinforce loop(eyelet) with grips, clips or clamps by preventing fraying caused by friction at the bearing anchor point to protect and extend the service life of the wire rope or sling. They are just one of the many types of wire rope fittings (ferrules, wire rope clips, terminals, etc.).
Wire rope thimbles are available in a variety of strengths and materials(carbon steel and stainless steel, see our post on Surface Finish: 4 Common Types You Should Know) but mainly they come in two different duty grades.
If you use it in high moisture or corrosive environments, recommend our stainless steel wire rope thimbles which can offer resistance to corrosion on the surface, particularly in marine applications.
Simply wrap the end of the wire rope around the outer groove of the thimble, lace the dead end of the wire rope past the U-bolt of the wire rope grips or a wire rope ferrule crimp to hold onto the bearing anchor point at the end of the thimble to prevent fraying caused by friction.
Once in place, put another wire rope clip as near the loop you just wrapped over the thimble. Turn nuts firmly but do not yet tighten to the proper torque, we recommend using a crimping/swaging tool to compress the ferrule firmly onto the rope to hold your thimble loop securely.
Alternatively, you can use a wire rope ferrule crimp to secure your thimble in place. this method is quick and easy to install. For further information on installation using a wire rope ferrule please – click here
Wire rope thimbles are used in conjunction with cable and rope to protect the eyes and will allow for smooth rope guiding around natural curves. So that the most important thing is to make sure the thimble eye securely fastened. Here are some tips for correctly using wire rope thimble:
Make sure that the cable thimbles size properly and securely fastened in the eye of the loop, not too loose or too tighten, so they can create an extra layer of support to connect with other properly sized rigging fittings.
While you are using a vinyl coated cable, you should multiply the actual size of the cable, usually use a larger size thimble than normal, for the actual diameter is the thickness of the vinyl coating plus the inside wire rope diameter. For example, if you are using a 5/16″ vinyl coated cable that is coated to 3/8″ diameter, you’d want to use a 3/8″ wire rope thimble.
