Section 3:
GATES
Application.
Gates facilitate control of authorized traffic and
3.1
its flow.
They establish specific points of entrance and exit to an area
defined by
fences.  They also function to limit or prohibit free flow of
pedestrian
or vehicular traffic, while establishing a traffic pattern for
restricted
areas.
Related Criteria.  Gates, as a part of perimeter fences, must be
3.2
as effective as their associated fence to provide an equivalent deterrent.
Gates will normally require additional hardening features due to their
location across entrance roads and the inherent vulnerability of their hinges
and latches.  Gates are known to be the weakest point in the perimeter
security fence and as such, you must pay attention to their requirements when
designing security fencing.
Materials used in fabricating and erecting chain-link gates must
be the same as the materials used for the associated chain-link fence. As for
security fences, aluminum pipe, poles, fabric, or accessories will not be used
or specified for security gate components.
Use American Society for Testing
and Materials (ASTM) standards to supplement Federal specifications when
further detail or criteria is desired.
3.3
Types of Gates.  Federal Specification RR-F-191/2 is the basic
criteria document for security fence gate design.  It provides specifications
for the following eight types of chain-link fence gates:
Type I - Single Swing Gates.
a)
Type II - Double Swing Gates.
b)
Type III - Single Cantilever Sliding Gates, Wheel Sliding
c)
Gates.
Type IV - Double Cantilever Sliding Gates.
d)
Type V - Single Overhead Sliding Gates.
e)
Type VI - Double Overhead Sliding Gates.
f)
Type VII - Vertical Lift Gates.
g)
Type VIII - Special Gates.
h)
The gate types listed above are the most common gate
configurations used for security fencing.  These include single and double
swing gates (Figures 12 and 13), single and double cantilevered gates (Figures
14 and 15), wheel-supported (V-groove) sliding gates (Figure 16), and single
