GETTING STARTED WITH SWING AND SLIDE GATE OPERATORS.
Always design, install and maintain safe gate access systems in accordance with UL 325 & ASTM F2200 standards.
• Only install the operator on gates used for vehicular traffi c.
• 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

**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 fi xed counter opposing edges or surfaces or
other fi xed objects is less than 406 mm (16 in) (examples are walls, curbs, berms, or other immovable objects).
The above examples are two of many installation possibilities and are for illustration purposes only.
See device and operator manuals for complete instruction.

Cross Section
entrapment zones are protected with a minimum of two independent
protection devices.
• A slide gate operator will only operate with a minimum of two independent monitored
entrapment protection devices installed in each direction, two in the open direction
and two in the closed direction
• A swing gate operator will only operate with a minimum of two independent monitored
entrapment protection devices installed in either the open or closed direction. If
no entrapment zone exists in the other direction, only one means of entrapment
protection is required in that direction
† Independent the same type of device shall not be utilized for both entrapment
protection devices.

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
entrapment zone.
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.

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 fi xed counter opposing edges or surfaces is less than
406 mm (16") in a location up to 1.8 m (6ft.) above grade.
