A turnbuckle, stretching screw or bottlescrew is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threadedeye bolts, one screwed into each end of a small metal frame, one with a conventional right-hand thread and the other with a left-hand thread. The tension can be adjusted by rotating the frame, which causes both eye bolts to be screwed in or out simultaneously, without twisting the eye bolts or attached cables.[1]
Turnbuckles are most commonly used in applications which require a great deal of tension; they can range in mass from about 10 grams (3⁄8 oz) for thin cable used in a garden fence, to tonnes for structural elements in buildings and suspension bridges.
Aircraftedit
Turnbuckles have been used in aircraft construction, especially during the early years of aviation. Historically, biplanes might use turnbuckles to adjust the tension on structural wires bracing their wings. Turnbuckles are also widely used on flexible cables in flight control systems. In both cases they are secured with lockwire or specifically designed wire clips to prevent them from turning and losing tension due to vibration.
Shippingedit
Turnbuckles are used for tensioning a ship's rigging and lashings. This device is also known as a bottlescrew in this context.
Sportsedit
Turnbuckles are used to tension the ropes in professionalwrestling rings and boxing rings, where they serve as the attachment between the ring ropes and ring posts, and are padded.
Entertainment industryedit
Turnbuckles are used in nearly all rigging performed in the entertainment industry, including theatre, film, and live concert performances. In entertainment rigging, turnbuckles are more commonly used to make small adjustments in line lengths. This is generally to make a flown unit sit parallel to the stage. Another way a turnbuckle could prove helpful is with making very minor height or angle adjustments.
Pipe systemsedit
Turnbuckles are used in piping systems as a way to provide minor adjustments for field inconsistencies. This also allows for a minimum amount of resistance when transferring the load to the support components.
Orthopaedicsedit
A type of splint is used for upper limb to produce gradual stretching over contracted joint by its turn buckle mechanism. Used to treat stiff elbow and Volkmann Ischemic Contracture.
