The DKS 1603 Barrier Gate Operator Automated Spike System is designed as a modular system, allowing for easy flexibility in different applications and easy installation. The 1603 Operator is designed with many advanced features and mechanically links the Spikes to the Barrier Arm. Ideal for parking lots, rental car agencies, schools, car dealerships, government agencies, or in any application where a higher degree of traffic control is preferred. A typical system will require the 1603 Operator, a Drive Extension, Tunnel Section(s) as needed, Spike Section(s) as needed, and an end cap. A Traffic Signal and/or Warning Sign is required with this system. Contact your professional DKS system installer, or DoorKing directly, for more information on complete system requirements.
