When two architecturally arranged wire ropes cross one another, it makes sense to put a wall mount there. However, it gets expensive when the trellis grid is very dense. For that reason, wire rope crosses without wall connection-- called 'rope cross clamps', or 'cross clamps'-- were developed. They fix ropes or growing rods together and prevent ropes "rubbing" against each other. Depending on the stability, aesthetic requirements and costs, different clamps are used, and you can find them listed here. Crossheads, for the making of wall supports, are discussed elsewhere. Learn below which "mesh sizes" match with which cross clamps and how rods are installed. >>> Price list
For various rope diameters, Fassadengrün has corresponding cross clamps, such as: SK 01515 (1.5-2 mm), SK 03012 (3 mm, available in AISI 304 and AISI 316), and SK 04015 (3-4 mm). They all have a graceful build but provide sufficiently strong holding strengths/clamping forces for your growing systems. SK 03420 is suitable for security-relevant applications; due to the M10 thread, even stronger holding strengths are possible. There are SK 03099 and SK 03006 as inexpensive options; here, the crosses are not screwed but pressed with pliers... later corrections then are rarely possible at the cross point. The connector SK 34515 is particularly suitable for combinations of cable and rods because, with two separate grub screws, strong holding strengths are made possible. Most cable cross clamps are made of stainless steel A2; only SK 03420 and SK 03006 are from A4.
FassadenGrün cross clamps have a greater holding strength compared with similar cross clamps from the Far East, primarily due to the shallow depth of the threaded hole, which is flush with the deeper cross grooves (see photo). Nevertheless, to form the internal thread deeply enough, an increased effort is needed. No concave pressure for the ropes arises, however, because they are clamped on an anvil without being concave. They can barely slide or slip, and a change of direction, or a bending due to the clamping, is not possible.
With large distances from intersection to intersection, i.e. large 'mesh' of more than about 1 square meter, there will be no free-floating cable crosses, but only cross mounts that are set with wall contact. This is the principle of cable system 5030.
For mesh sizes under 1 square meter, all peripheral points are completed with cross mounts, but inside the field, freely floating cable crosses are set on the architectural line. That is the principle of cable system 5040.
With mesh sizes of 30 x 30 cm and smaller, cross holders on the edge of the field can also be exchanged for free-floating cross clamps. This is the principle of cable system 5050.
If climbing rods of 4 or 5 mm are used for the compression of architectural ropes, they can be fastened with SK 03420 or SK 34515- both with each other and with cable thicknesses 3 or 4mm. (Links to product sheets on the left.)
Cable cross clamps are also suitable as a temporary installation aid for cable systems with cross holders, where a closed cable frame is to be mounted (for example with 4020 and 7040). Instead of 2 vices, only one is then needed, and if the kit does not already contain one or more cross mounts, another suitable one will be ordered.
