What are Rigging Screws and Turn Buckles ?
Rigging screws and turn buckles are sometimes referred to as a wire rope tensioner, bottle screws, barrel strainers or straining screws. They 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. Usually 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 sometimes 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.
These fittings have the closed barrel type centre and so look more aesthetically pleasing whilst Turn buckles have an open body/centre piece which turns around the visible screws. The definition of a turn buckle 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.
