Product Overview
The ROCK/F fixed bollard is designed for robust perimeter protection, featuring a cataphoresis treatment for enhanced durability. The bollard stands 700 mm high above ground with a diameter of 275 mm, making it ideal for blocking access in pedestrian areas and protecting passageways.
Key Features

700 mm height, 275 mm diameter
Cataphoresis treatment for enhanced durability
Retro-reflecting film for high visibility
Effective for perimeter protection of sensitive areas

Product Description
The ROCK/F fixed bollard provides a reliable solution for perimeter protection in sensitive areas. Its robust design and cataphoresis treatment ensure long-lasting performance. The upper part of the bollard is equipped with retro-reflecting film, offering high visibility even at night or in poor visibility conditions.
The bollard is particularly effective as an access block in pedestrian areas and for defending passageways where gates are not present or could be breached. The concrete base is provided without reinforcement, and the foundation base (art.ROCK/FB) is available as an accessory.

<p>ROCK Hydraulic Retractable Bollard - Height 700mm / Ø 275mm (230V)
ROCK is a hydraulic retractable bollard with linear guide system with&amp;nbsp;chrome-plated steel&amp;nbsp;cylinders. The shaft above ground is&amp;nbsp;700 mm&amp;nbsp;high and the concrete base is provided without reinforcement. It has a&amp;nbsp;break-through resistance&amp;nbsp;up to&amp;nbsp;138kJ.
&amp;nbsp;
GREATER PROTECTION FOR SENSITIVE AREAS
ROCK is a perimeter protection device for sensitive areas. It is effective as an access block in pedestrian areas, as well as an excellent solution to defend passageways where the gate is not present or is present but could be broken through.&amp;nbsp;
&amp;nbsp;
IMPACT RESISTANT AND NOT ONLY
The ROCK bollard is not only breakthrough resistant up to 138kJ, but is also weather resistant. This is because its extractable part undergoes a double treatment: anti-corrosion cataphoresis and polyester powder coating.
&amp;nbsp;
BRIGHTER, SAFER
The upper part of ROCK is equipped with a reflective band with high luminous efficiency and red led diffusers. This allows you to see the bollard during the night and when visibility is poor.
&amp;nbsp;
EASY MAINTENANCE
The hydraulic pump that moves the ROCK is integrated in the removable structure of the bollard. This means that routine maintenance operations can be carried out by the professional quickly and easily, without having to use machines to lift the shaft.
&amp;nbsp;
REMOTE CONTROL
Thanks to the DEAuser&amp;nbsp;app, the movement and status of the ROCK bollard can be effectively controlled from your smartphone.&amp;nbsp;
