Although the blocker only requires a relatively shallow foundation to accommodate the 215 mm height of the base frame, the unique folding skirt provides the same degree of protection as a conventional solid skirted blocker requiring foundations of some two and a half times deeper. Thus, in many cases the 10506 avoids the necessity to re-route underground services. Additional protection can be provided using photo beam systems tailored to the particular application. It is recommended that the blocker is installed with vehicle detection loop systems.
The CSG model 10506 Shallow Depth Blocker has been tested at the Motor Industry Research Association (MIRA) The test was carried out using an Iveco (Ford) Cargo rigid truck ballasted to a test weight of 7755 kg and impacted the blocker at 80.8 km/h. Under requirements contained within British Standards for vehicle security barriers, PAS 68:2010 the test achieved a classification of Retractable Blocker V/7500 (N2)/80/90:0/25.
