GTA 3 aluminium hook for tiles and strips

Name: GTA 3 aluminium hook for tiles and strips
Brand: fischer

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 you to adjust the distance of the rail from the top of the tile, while the lower adjustment position allows you to adapt the hook to different tile and ventilation strip thicknesses. The horizontal adjustment at the base of the hook allows the fastening 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 rail 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.

3 adjustment positions: upper adjustment position for rail/tile top distance, lower adjustment position for different tile thicknesses plus ventilation strip, horizontal adjustment position on the base to offset the fastening point from the roof;
Wide base: adapts supports that can only be used in certain points;
High centre distances: the great load-bearing capacity allows the use of fewer hooks;
Controlled deformation: designed not to bend or damage the tiles;
Pre-assembled: ready to use without the need for additional accessories;
Strong and lightweight: made of aluminium to last the entire life of the system;

Functionality

Fix the base element to the substructure using suitable fixing (minimum 2 fixings).
Move the middle element to the right or to the left according to the desired position.
Raise or lower the middle element according to the height of the tile to be surmounted.
Tighten the M8 connection nut between the base element and the middle element with a torque of 10 Nm.
Raise or lower the upper element according to the height of the upper tile and the desired position of the SolarFish or SolarLight profile.
Tighten the M8 connection nut between the middle element and the upper element with a torque of 10 Nm.
Place the SolarFish or SolarLight profile above the upper element in front of the profile fixing element.
Insert the profile fixing element inside the lateral groove of the profile (high side for the SolarFish profile and low side for the SolarLight profile).
Slide the profile stop to align the profile in the correct position forwards or backwards.
Tighten the M8 connection nut of the profile fixing element with a torque of 10 Nm.
