Description / Price
Wall mount -- 'cross mount' -- made of stainless steel A4, smooth shaft d = 12 mm, made of particularly rigid (resistant to bending) A4-80, with integrated anchoring system (patent protected). Phillips d = 20 mm with set-screw, lock nuts, lock nut, thrust washer (pressure disc) for the borehole closure, neoprene gasket, plastic spacer body with expansion indicator, expansion cone and metric plug (anchor) (both from galvanically galvanized steel). Wall clearance 90 mm. Simple assembly. A similar head is also available separately. >>> Price
Standard wall mount for Massive Kits. For 3 and 4 mm cable. For a simple or crosswise cable guidance, if necessary also triple guidance. The distance from mount to mount should preferably not exceed 1.8 m with horizontal cables and 2.2 m with vertical cables. Compatible with many wall types; please check suitability via the link. Due to the spreading pressure, not suitable for border/edge areas; minimum distance from the edge of free-standing walls-- approx. 25 cm. Also directly into solid wood d > 8 cm can be used. Not for walls with insulation, wood panelling and pre-fab construction. Strong stem-forming plants such as wisteria, knotweed and tree shrike need to be guided parallel to the cable, avoid continuous looping around steel wire rope as described with wisteria. Please also refer to the information on the selection of appropriate cross mounts.
If necessary, please refer to the instructions on drilling work. Drill hole: 16 mm in diameter and 9 cm deep; expand the front half of the borehole, if possible, to about 16.5 mm diameter by gently abrading the hole wall during drilling. For optimal sealing, the surface should be reasonably flat or made so (sanded down). The already pre-assembled wall mount is led into the cleaned bore-hole, struck lightly on the head (cross head) (figure 06) if necessary, until the rubber seal comes in contact with the wall. If the mount can only be introduced with difficulty, the hole can be drilled again and widened by applying lateral pressure of the drill. If, on the other hand, the drill diameter becomes too large, rotate the rawl plug (dowel) a little closer/tighter before insertion. By slightly buckling the spacer body (the mount), a better 'grip' is then possible at the borehole wall, and the element does not rotate when tightening. Then use an open-ended wrench on the double nut and turn (screw in) (Figure 07). The wrench must engage the broad front nut. After a few turns - clockwise -as when inserting an ordinary screw - the inner metric plug is spread open, recognizable by the squeezing of the outside protruding plastic sleeve (spread indicator - Image 08). If the protruding plastic sleeve is completely crushed (Figure 09), the holder will be aligned according to the cross-slots. The further installation proceeds as described for Massive Kits.
Special Features with Vertically Perforated Bricks
Installing in perforated bricks with a dense structure is usually no problem. In porous, perforated bricks, such as Poroton (hollow bricks), Eder, etc., use is possible if the bricks are of category Hlz 12 or higher...i.e. vertically perforated bricks with compressive strength class 12. With a lower strength class, the inner webs should be as wide as possible. The structure of the chambers must ensure ensure that the rawl plug (anchor) head can grip at least the second web/footbridge; this must begin at least 6 cms inside behind the plaster outside edge (not stone outside edge!). The assembly ends in vertically perforated ('hollow') bricks (with picture 08/09; the last strong turn of the wrench (picture 10) is omitted. If there is still a clear 'crackling' in the brick during assembly, you can unscrew the cross mount again and exchange the entire product for adhesive plug (anchor) WM 12191. When in doubt, always use the element WM 12191, preferably with adhesion (gluing).
Special Features of Aerated Concrete
In aerated pore concrete ("air/gas/cellular concrete," e.g. "Ytong"), the wall mount can only be used to a limited extent if no strong twiners like wisteria, knotweed, tree shrike, etc.. are planted. It is then better to choose 3 mm of cable (instead of 4 mm), and the grub screws shouldn't be tightened too strongly. When in doubt: the mount can be set at a closer distance, or as an alternative, choose the heavy construction style with its deeper anchorage in order to prevent a breakage of the stone. In aerated concrete, the wall mount is hammered in and then tightened. It makes sense to drill a short, max 1.5 cm deep pilot-hole (d = 16 mm) to penetrate the outer plaster layer in order to avoid spalling when driving in. Then drill a pilot hole 6 - 8 mm in diameter-- even better a mandrel (awl)-punched hole-- in order to compact the surrounding material. It make take then 10 or more 'turns' until the anchor/plug has sufficiently compacted the surrounding stone material and and taken 'grip.'
Special Features - General
This cross holder can be screwed out of the anchoring (rawl plug) again.
