Technical specification

Description

Use

• Rooftop support system for outdoor installations. (It could also be used on the floor of industrial plants indoors or outdoors)
• For support of cable trays, cable ladders and cable conduits.
• When used over PVC-P waterproof sheets check with technical assistance.

Advantages

• The Rooftop supports are held in place on the roof by their own weight. It is not necessary to fix them to the floor.^{(1, 2)}

• Support ready-to-install.
• Corrosion Resistant. (the rail is made in thermoplastic material U48X).
• The rooftop support is insulating, electrically separates the cable trays from the roof surface and does not require earthing.
• CE marking acc. IEC 61537 compliance. Loads of the supports tested according to the same international standard of LV cable trays.
• Good fire performance. Combination of Halogen free thermoplastic compound U48X own formulated rail, concrete base and rubber bottom.
• Immediate availability from our logistics center thanks to a complete stock of all the parts.

Design

• Safe, easy and quick mounting.
• Provided with an insulating rail made with solid walls and manufactured by extrusion. It is compatible with spring strut nut M8 ref. 60710-A4 and ref. 60710-C6 or other standard channel nut 41 acc. to BS 6946.
• Absence of sharp edges or pressure points which might damage the rooftop layer.
• Rubber bottom avoids damage to the rooftop layer and ensures a good friction coefficient.
• Good performance with exposure to the UVs and to the elements.

Mounting instructions

• To fulfil the characteristics defined herein, the installation must be carried out in accordance with the manufacturer`s assembly instructions provided in the main product packaging and also available on the website www.unex.net.
