Specifically designed to protect people, buildings and infrastructure from hostile vehicle attack, the Impakt Defender is a surface mounted IWA14 rated vehicle security barrier (VSB).

Manufactured from 100% recycled rubber, bonded with polyurethane for strength, the Impakt Defender’s unique shape, with its large footprint, deforms on impact to increase stopping performance. Its tough construction enables it to be installed almost anywhere, removed and used again and again.

Each 430kg, 1m x 1m x 1m solid rubber unit is connected by steel securing cables, providing the flexibility to protect both entrance areas and site perimeters against hostile vehicle attack. Requiring no foundations, the surface mounted system can be rapidly deployed as a temporary or permanent security measure, unanchored or anchored.
