fischer aluminium hook GTA 3

Top Features
  • Three adjustment possibilities: upper adjustment position for rail and top tiles distance, lower adjustment position for different tile thicknesses plus ventilation strip, horizontal adjustment position on the base to offset the fixing point from the roof.
  • Suitable for tiles with a ventilation layer for a total thickness of 55 to 67 mm.
  • Quick and easy coupling of hook and rail joint without additional screws.
  • The wide base plate enables to vary the exact fixing point.
  • Made of AW 6060 T66 aluminium.

The advantages / Product description

Aluminium hook with 3 adjustment positions for the installation of photovoltaic systems on tiled roofs with ventilation strips of variable thickness.
Advantages
  • Three adjustment possibilities: upper adjustment position for rail and top tile distance, lower adjustment position for different tile thicknesses plus ventilation strip, horizontal adjustment position on the base to offset the fixing point from the roof.
  • The wide base plate enables to vary the exact fixing points.
  • The high centre distances and its great load-bearing capacity allows the use of fewer hooks.
  • Controlled deformation avoids bending or damaging the tiles.
  • The hook is already pre-assembled, so there is no need for additional accessories.
  • Due to the strong and lightweight aluminium the hook is very long lasting.
  • Quick fit joint for connection to the rail without further accessories or bolts. Compatible with both SolarLight and SolarFish rails by rotating the joint.
GTA 3 is an aluminium hook for building photovoltaic system structures on tiled roofs with ventilation strips of variable thickness. The upper adjustment position allows to adjust the distance of the rail from the top of the tile, while the lower adjustment position allows to adapt the hook to different tile and ventilation strip thicknesses. The horizontal adjustment at the base of the hook allows the fixing point to be offset from the roof with respect to the exit point of the hook from the tile. The GTA 3 hook is equipped with a quick coupling joint for connecting the hook to the profile in seconds and without the need for additional bolts; compatible with SolarLight and SolarFish rails. The shape of the hook is designed to withstand the snow and wind loads required by law without touching the tile.
Properties
  • Hook in aluminum alloy AW 6060 T66 and AW 6082 T6 in accordance with EN 755-2:2016;
  • Class A2-70 stainless steel bolts in accordance with EN ISO 3506-1/2;2010.

Application and approval

Applications
  • Fixing of photovoltaic systems on tile roof supported by strips of variable thickness.
  • Suitable for both SolarLight and SolarFish rails by rotating the rail-locking element.
Approvals
  • TUV - R 60154136

Assembly instruction

Functionality
  • Determine the centre distance of the hooks according to the snow and wind loads in the installation area.
  • Determine the position of the hooks according to the load-bearing structure and system layout.
  • Lift the tile and secure the base of the hook using the appropriate anchor determined according to the type and layers of the load-bearing support.
  • Make the height and width adjustments required by the type of roofing and tighten the screws of the adjustable joints to lock the hook in position.
  • Insert the joint on the top of the hook inside the side groove of the rail. The joint can be rotated to adapt to SolarLight or SolarFish rails.
