Features:
 Nominal overall height 11’7” grade to top of barrier
 Nominal gate height 9’9”
 Opening sizes vary per customer needs
 Available in either all electric or hydraulic gate operator
Benefits:
 DOS K12/L3 Crash tested
 Minimal effort to install with low maintenance
 Aesthetically pleasing with functional architectural design
 Maximum flexibility allowing for chain link fence, pickets,
or anti-climb material

Open: Barrier immediately reverses direction of travel and moves to the unsecured position in standard
operating time (slightly faster due to reduced travel)
BARRIER IS BETWEEN OPEN AND CLOSED AND MOVING TO A UNSECURE POSITION.
Close: Barrier immediately reverses direction of travel and moves to the unsecured position in standard
operating time (slightly faster due to reduced travel)
Open: Barrier moves to the unsecured position in standard operating time
