The FEETNET chained system is suitable for mounting photovoltaic modules on flat roofs.
The modules are blocked on the short side. It is possible installation with three different inclinations 5°, 10°, 15°. The choice of the base profile depends on the wind load conditions at the installation site.
Stackable mats are placed between the cover and the base profile to increase friction.
The positioning of additional weights is made easy and flexible by the use of suitable accessories to avoid punctures on the roofs.
Only mounting on the short-side panel
Pre-drilled lower fins for mounting hammer head screws or polycarbonate UV hooks
The high NET profile (code PRC0535) with high inertia is suitable for areas with high wind load. The low NET profile (code PRC0384) is suitable for areas with low wind load.

The jig consists of three spacers with two aluminium profiles.
The special geometry of the jig allows the positioning of both the base profiles and the front and rear supports. It is possible to adjust the distance between the three spacer supports and consequently allows you to block the aluminum profiles with the two pre-assembled screws
A rubber mat is placed between the base profile and the ground with the purpose of absorbing the deformations of the structure and generate friction with the mantle coverage.
The mat is fitted to the aluminium base profile by snap-fitting serrations placed on the lateral side.The bottom surface is knurled to increase friction and at the same time favor the water outflow.
The additional weights are placed on a plastic ballast support with four protruding fins.to increase the contact surface.
Support presents also two side fins necessary to hold the concrete block avoiding overturning / translation due to wind load.
If the ballast has larger dimensions, to not be contained between the two fins, the support can be also supplied without them: in this case the friction between the support and the concrete block is increased by the presence of wedge-shaped protrusions on the flat part.
The individual front and rear brackets are attached to the base profile using two hammer-head screws. Alternatively, the UV-resistant polycarbonate hook can be used instead of a hammerhead screw.
In addition, the special hammer head shape allows the hook to be fixed to the base profile by inserting and turning the hammerhead into the groove.
A cross brace is used to stiffen the frame. It is connected to the various base profiles by means of a pre-assembled aluminium hook.
The latter consists of two pieces connected by a hammerhead screw.
The two pieces lock the angle profile in place without the
need to drill holes in it.
The bracing, mounted in pairs, also acts as a support for
additional ballast, with the advantage of being able to shift the position of the fastenings thanks to the use of the
pre-assembled hook.
