The Retention Barrier forms the basis for a modular system for incremental build-up for stationary, vertical travel, manual or automatic versions. Conversion into stationary, folding-type systems is also possible.

Suitable for crack-free surfaces with up to 30 mm (± 15 mm) of floor/ground unevenness, e.g. concrete, corrugated sheet metal, tiles, stones, asphalt, etc. Special feature: Sealing of railroad tracks.

The Retention Barrier features a trapezoidal, integral hollow profiled aluminium section with a compressible, highly adaptable special seal affixed to the bottom side and end faces.

It is securely mounted in two mounting fixtures to the left and to the right of the opening to be secured and tightly sealed against the building or structure. Installation within the doorjamb is possible.

A heavy vertical tensioning device is bolted on each of the mounting fixtures with which the necessary force can be applied to press the body of the barrier into place against the mounts and the floor/ground and compress the floor/ground seal. A leak-proof closure is ensured in this manner. The position of the levers can be selected at will by means of special consoles. The contact pressure is adjustable.

Wall mounts are included in the product package to provide for orderly storage.

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.
