Rigging screws and turnbuckles are sometimes referred to as a wire rope tensioner,bottle screws,barrel strainers or straining screws and are a special type of fitting which are used to enable the tensioning of wire ropes.Once fitted the tension of the rope can easily be adjusted whenever you need to,whether it is to tighten or loosen the rope.All that is needed is to turn the main body or barrel.
They are commonly used in rigging applications and anywhere that the wire will need tightening to a unique rigidity to fit its objective,for example,bridges, balustrades,staircases and hanging shelves.They are often utilised for use as barriers (instead of fencing) to avoid access to certain areas or as a safety barrier,but are easy on the eye.For example they are used on castle ramparts to allow the public to be able to walk around them safely,yet they do not intrude too much on the original nature of the buildings.
Rigging Screws have the closed barrel type center and so look more aesthetically pleasing whilst Turnbuckles have an open body/center piece which turns around the visible screws.The definition of a turnbuckle is type of coupling which possesses internal screws that are used to connect two wires or rods,end to end in order to adjust the tension.
