The BLS K12 – 10 m is available for large clear widths of opening up to 10 m. Our crash rated Barrier Lift System (BLS) completely destroys the chassis of any vehicles trying to break through. Even high speeding heavy vehicles will be stopped reliably. The BLS fulfils the highest security level! It can be used individually or in combination with other PPG products to achieve a sluice arrangement forming a highly secure vehicle check point.
