Fence
All openings of a horizontal slide gate are guarded or screened from the
bottom of the gate to a minimum of four (4) feet (1.22 m) above the ground to
prevent a 2 1/4 inch (57.2 mm) diameter sphere from passing through the
openings anywhere in the gate and in that portion of the adjacent fence that
the gate covers in the open position.
(ref. UL325 56.8.4.a.2 and ASTM F2200 6.1.2)
The operator is intended for installation only on gates used for vehicles.
Pedestrians must be supplied with a seperate access opening. The
pedestrian access opening shall be designed to promote pedestrian
usage. Locate the gate such that persons will not come in contact with
the vehicular gate during the entire path of travel of the vehicular gate.

Entrapment Area

This area between the gate and fence has a high risk of entrapment. The gap between the fence and gate should not exceed
2 ¼ inches. Install a filler or barrier in this area to reduce this gap to 2 ¼ inches or less.
Install a contact sensor (type B2) on the fence to help minimize the risk of entrapment in this area.
