The Retention Barrier has been developed to accommodate loading docks and ease of use. The system is suitable for crack-free surfaces with up to 0.8 inch (± 0.4 inch) of floor/ground unevenness, e.g. concrete, corrugated sheet metal, tiles, stones, etc.

The Spill Barrier is comprised of three, integral hollow aluminium profiled bodies with a compressible, highly adaptable seal affixed to the lower side. The seal is chemical resistant and fire retardant according to DIN 4102-B1 (not easy flammable).

The rotating mounts are securely fixed next to the opening to be sealed. The barrier bodies are firmly bolted into the hinge and connected by a transverse barrier. In stand by, the barrier stands vertically and is protected against being closed unintentionally. This is in line with German UVV accident prevention guidelines.

To close, the locking pin is removed and the Retention Barrier is lowered manually. The Spill Barrier is locked into place with a heavy duty lever. The contact pressure of the barrier is adjustable using the tensioning device.

With certain lengths and heights, closure of the barrier is counterbalanced with weights. Gas-charged springs are standard for small and medium-size barriers. Hand cranks in combination with gas-charged springs are used for 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. Stainless steel is available upon request.
