GETTING STARTED WITH SWING AND SLIDE GATE OPERATOR.
• Only install the operator on gates used for vehicular traffic.
• A separate pedestrian entry/exit must be clearly visible to promote
pedestrian usage and located so pedestrians do not come in contact
with the vehicular gate while it is moving.
• Install two independent
†
entrapment protection devices protecting
each entrapment zone.
• Pickets of a slide gate must be designed or screened to prevent
persons from reaching through, or passing through a gate.
• Every Installation is unique. It is the responsibility of the installer to
ensure all entrapment zones are protected with a minimum of two
independent
†
entrapment protection devices.
• Beginning August 1, 2018, for a slide gate operator to function,
the operator will require a minimum of two independent
†
monitored
safety entrapment protection devices in each direction: two in the
open direction, two in the close direction.
Always design, install and maintain safe gate access systems in accordance with UL 325 & ASTM F2200 standards.

If gaps (xxx)
between vertical
bars of the gate or
fence are less
than 2 1/4", no
further screening
is required.
For gaps (xxx)
equal to or larger
than 2 1/4", a wire
mesh screen must
be applied to the
gate. Wire mesh
screen openings
must be smaller
than 2 1/4". The
minimum height of
wire mesh screen:
6 ft. above grade.
SLIDE GATE OPENINGS GUIDELINES
Openings of a horizontal slide gate must be smaller than 2 1/4"
or else be guarded or screened. These design rules apply to
both the moving gate as well as the portion of adjacent fence
that the gate covers in the open position. See Illustrations
below.
SLIDE GATE SPACING GUIDELINES
Slide Gate Gaps
A gap, measured in the horizontal plane
parallel to the roadway, between a fixed
stationary object nearest the roadway (such
as a gate support post) and the gate frame
when the gate is in either the fully open
position or the fully closed position, shall not
exceed 2 ¼ in.. Exception: All other fixed
stationary objects greater than 16 in. from
the gate frame shall not be required to
comply with this section. Any gap must be
protected. Install safety device to protect
draw-in zone.
**Swing Gate Entrapment Zones:
Locations between a moving gate or moving, exposed operator components and a counter
opposing edge or surface where entrapment is possible up to 1.8m (6 ft) above grade. Such locations occur if during any point in travel:
a) The gap between the bottom of a moving gate and the ground is greater than 101.6mm (4 in) and less than 406mm (16 in); or
b) The distance between the center line of the pivot and the end of the wall, pillar, or column to which it is mounted when in the open
or closed position exceeds 101.6mm (4 in). Any other gap between a moving gate and fixed counter opposing edges or surfaces or
other fixed objects is less than 406mm (16 in) (examples are walls, curbs, berms, or other immovable objects).
Definitions
Entrapment:
The condition when a person is caught or held in
a position that increases the risk of injury.
Slide Gate Entrapment Zones:
An entrapment zone exists if
at any point during travel, the gap between the moving gate
and fixed counter opposing edges or surfaces is less than 406
mm (16”) in a location up to 1.8 m (6ft.) above grade.
†
Independent the same type of device shall not be utilized for both entrapment protection
devices.
