Security Blocks

Marshalls CPM Redi-Rock Vehicle Security Blocks (VSB) are a fast to install Lego like system that has successfully been tested by the Transport Research Laboratory (TRL) using the BSi specification PAS 68:2007 and achieved a classification of V/7500 (N2)/48/90:1.6/0.0

To achieve this the freestanding concrete blocks systems interconnected with steel cable successfully arrested a 7.5 tonne lorry at an impact speed of 48 kmph (30 mph) with only 1.6, penetration of the load carrying space.
