Description / Price
Turnbuckle fork-fork, made of stainless steel A4, marine design, closed version with threaded sleeve, with right and left-hand thread M6, length approx. 160 -220 mm, tension distance max. 6 cm, clevis width approx. 6-7 mm, clevises (fork heads) welded with a mutual jet locking (clamping) nut.
Mostly in the maritime sector. For wire and cable up to 4 mm diameter. For wire and cable trellises as a tensioning and adjusting element. The forks can be mounted directly (i.e. without additional connecting elements) into all FassadenGrün wall eyebolts. An O-ring is required as a link/intermediate element when hooking into earth anchors. In the case of high vertical cables, you'll have to consider whether the turnbuckle will be integrated at the top or at the bottom. Higher installations are tamper-proof and therefore better for public street areas, while lower installation means easy-access should re-tensioning be required. It is also possible to seal the lock nuts with an adhesive to prevent them from loosening, which, however also makes retightening more difficult or even impossible. Please refer to our general information on rope clamps, etc.. for further support as needed.
Before installing the turnbuckle, loosen the locknuts and push them up to the threaded forks. (note: right-hand AND left-hand threads!) Then screw the forks out so far that their threaded shafts protrude about 1 to 1.5 cm into the closed clamping sleeve. When mounting the turnbuckle in a cable line, i.e. in prepared cable loops or wall-mounted eyebolts, the safety pins may have to be removed and the bolts pulled out of the forks. But it is usually easiest to make the rope loops directly on the turnbuckle without dismantling the turnbuckle.
When installing in the cable path, make sure that the cable is already slightly taught. Then the final tensioning can be achieved by rotating the sleeve a few turns, passing a pin, nail or the like through it so that both sides are pulled evenly towards the centre. 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, such that the use of tensioning elements (turnbuckles) is mostly unnecessary. Tensioners are sometimes recommended for easy kits, in cases where there are many points of deflection or in the case of long rope sections that don't have intermediate mounts. The number of tensioners in a trellis system can be reduced by a sensible arrangement and networking of the cables. In most cases it is possible to connect at least two cables together for which one tensioner becomes 'responsible' for both.
