Description / Price
Turnbuckle made of stainless steel A4, maritime design, closed design with threaded sleeve, with right and left-hand thread M6, length approx. 160 -220 mm, tension distance max. 6 cm, breadth of both forks approx. 6-7 mm, clevises (fork heads) welded with a mutual jet locking nut.
Mostly in the maritime sector. For wire and cable up to 4 mm diameter. For wire and cable trellises as tensioning and adjusting element. The forks can be mounted directly, so without additional connecting elements, into all FassadenGrün wall eyelets. Ground/earth anchors with a round ring (eyelet) is necessary as a link/intermediate element. In the case of high vertical cables, you'll have to consider whether a turnbuckle will be inserted at the top or on the bottom. The tensioner is easier to reach at the bottom should re-tensioning be required... but, high installation is tamper-proof and therefore preferable in public street areas. With this tensioner, it may also be possible to permanently seal the lock nuts with an adhesive to prevent them from being unscrewed, which, however also makes retightening more difficult or even impossible. Please refer to the general information on rope clamps, etc.. for further support if needed.
Before installing the turnbuckle, loosen the locknuts and turn them up to the threaded forks. (Attention: right-hand AND left-hand threads!) Then the forks are screwed out so far that their threaded shafts protrude about 1 to 1.5 cm into the closed clamping sleeve. For the subsequent installation of the entire tensioner in the cable path, i.e. into prepared cable loops or wall mounted eyelets, the safety pins and bolts may need to be removed from the forks. It is, however, often simplest to make the rope loops directly on site of the undismantled screw tensioner. The installation into the cable course should be carried out in such a way that cable or wire is already slightly tightened. Then the final tensioning can be achieved with a few turns of the tension sleeve. A mandrel (awl), nail, or the like is inserted through the centre of the sleeve and the sleeve is turned so that both threaded forks are pulled inwards evenly. Both forks are then screwed into the sleeve with about half the thread length; this gives a harmonious look, and there is still enough clamping room for any re-tensioning that may be necessary later. Finally, the two threaded nuts are screwed back onto the sleeve and tightened there. This secures the set tension.
FassadenGrün cable systems are designed to be economical and so designed such that the installation of clamping elements is unnecessary. Screw tensioners (screw clamping fixtures) are sometimes recommended for Easy Kits or in cases where there are many points of deflection and also long single ropes without decoupling the rope sections (i.e. without cross mount). The number of tensioners in a trellis system can be reduced by a sensible arrangement and the cross-linking/networking of cables. In most cases it is possible to connect at least two cables together via deflection and to incorporate the tensioner in their midst, such that it becomes 'responsible' for both cables.
