Suitable for crack-free surfaces with up to 20 mm (± 10 mm) of floor/ground unevenness, e.g. concrete, corrugated sheet metal, tiles, stones, etc.

The Retention Barrier is comprised of two trapezoidal, integral hollow aluminium profiled sections (elements). A compressible, highly adaptable special seal is affixed on their lower side and end face.

Both swivelling devices are securely mounted and sealed to the floor/ground and wall next to the opening to be protected. The barrier bodies are securely bolted into the hinges. These sections stand vertically in the resting position and are secured in this position in conformity with accident prevention measures to avoid unintentional release. When being deployed, the barrier body without the tensioning device is first unlocked and lowered into the closing position. The opposite barrier body with the attached tensioning devices is then deployed in the same manner and both elements tensioned against each other and against the floor/ground surface.

With certain lengths and heights, both closure barriers are counterbalanced with weights in the factory. Gas-charged springs are standard. Operation by means of a manual winch is recommended for very large barriers.

Barrier bodies and mounting fixtures are furnished with a red paint finish, preferably “traffic red” RAL 3020. The remaining metal components are galvanized or made of aluminium.
