Canadian Doormaster Electric Ltd. installs Vehicle Blockers for high security critical areas, such as: governmental buildings, financial institutions, educational institutions, or any location which might be susceptible to un-authorized vehicle access. Alternatively called Road Blockers, these devices provide a very high degree of security for government or military installations when a vehicle must be stopped at an access point. These can have electrical or hydraulic operation, and numerous special features including a "fan-fold" unit that does not require excavation of the road surface.
