End Caps for Wire Systems

In the case of some rope tensioning systems, ropes with "terminals" are held in such a way that no free ends are visible. For cost reasons, FassadenGrün chooses another way, which does leave rope ends visible. Ends of wire ropes should not unravel themselves, as injuries are then possible. We provide the necessary protective parts for these ends; they are included in the prefabricated kits. Here you will find detailed information on the safeguarding of rope ends. >>> Price list

Historical Tension Wires

In historical fastening systems -- when wire rope did not yet exist -- 4 mm steel wires were threaded at the ends, put through eyelets, and then tensioned tightly by means of a threaded nut. These tension wires were the precursors of the present-day rope tensioning systems.

 

 

Tensioning Wire Systems with Terminals

What works for a thick wire might cause problems when using a steel wire rope: How can the rope end be threaded? For this purpose, "terminals" were invented: architectural ropes precut to exact measure/dimension are provided with such a terminal on both ends. This terminal, for instance, has an external thread analogous to the tension rope with which the rope is inserted into a holder and tightly tensioned from behind with the help of a threaded nut. In the case of high-grade tensioning wire systems, our competitors often work with sophisticated threaded and fork terminals. They are usually rolled with special machines and are correspondingly expensive. Alternatively, there are do-it-yourself terminals, in which the rope is fixed by grub screws transverse to the fiber direction; the rope end is then virtually part of the threaded rod. But even this solution remains price-intensive. Therefore, Fassadengrün forgoes terminals altogether and has the ropes tensioned by hand, as described under 'Mounting.' But how are the protruding rope ends treated? 

Clean Cut

First, ropes need to be cleanly cut-- preferably with special wire rope cutters. Alternatively, if only a few steps are necessary, the cutting line can be marked off with insulating tape and cut with an angle grinder.

 

 

End Sleeves

FassadenGrün offers special end sleeves made of stainless steel for the rope end. These special end sleeves (EH 00000) are secured (squeezed) with customary pliers or water pump pliers. The wire rope can either end flush with the end sleeve or protrude 1-2 mm. Different pliers result in different squeeze patterns, all of which have the same effect. After the sleeves have been adequately squeezed, they cannot be removed by hand; their durability in rope tensioning systems is unlimited.

Alternatives

There are a few alternatives (see picture). 1) You can wrap the rope end with duct, insulating, or teflon tape. 2) Somewhat more durable are end sleeves made of plastic or synthetic materials (Note: until further notice, no longer in stock). 3) Even aluminium sleeves are a possibility. These are, however, subject to later electrolytic corrosion.
