Wall fitting/anchor for stainless steel trellises with 8 (10) mm thick wires. For heavy loads. Distance to wall 10-12 cm. The distance from mount to mount should ideally not exceed 1.5 m. For all types of masonry, but especially for porous lightweight perforated bricks (hollow-bricks/"Poroton") and sensitive edge areas in which expansion pressure cannot be built up, as with GH 12153. Wall distance adjustable during adhesion, recommended 10 cm, maximum 12 cm. Please also read the general tips on how to correctly secure a trellis to the wall.


Recommended Tools

Hammer drill HB 16210 for all drillings with or without sieve sleeves.



If necessary, please follow the guidelines we've provided for drilling and the instructions for composite mortar. For optimal sealing, the surface should be reasonably flat or be made so (sanded down). With hollow masonry, use (in addition) sieve rawl plugs/anchors; if installing extra long SD 16130, then drill 16 mm and approx. 140 mm deep. Slide the moving parts of the cross mount forward, press in the composite mortar, rotate the shaft to insert, position it and, if necessary, secure it against sagging from below (photo). With a cloth remove any mortar that swells out. After setting/drying, slide the spring washer, cover plate/disc, and gasket towards the wall and clamp by tightening the lock nut. Then align the groove -- e.g. with head and flat nut lock against each other (using a screwdriver to hold them crosswise through the groove).



For all special cases, the cross mounts are available with different shaft lengths at no extra charge. For through-hole installation on supports of carports etc., a bolt ('counter pressure') set is available.
