Sliding gates

  • Chain brackets cannot extend pass the gate. ASTM F2200
  • Rolling wheels shall be covered within 8’ of grade. ASTM F2200
  • Cannot pass a 2.25” sphere through gate and adjacent fence with 6’ of grade. ASTM F2200 §6.1.2
  • Cannot have a cavity greater than 2.25” between gate & draw post. ASTM F2200
  • Draw Post shall be protected from entrapment. UL 325
  • Positive Stops required. ASTM F2200
  • Receiving guide shall be recessed behind receiving post or fixed object if less than 8’ grade.

Swing gate - no protection for reach through required.

  • Shall not exceed 4” between gate & hinge post when open unless protected. ASTM F2200

Definitions – ASTM F2200

4.23 Slide gate entrapment zone: Locations between a moving gate and a counter opposing edge or surface where entrapment is possible up to 6ft above grade. Such locations occur if during any point in travel the gap between a moving gate and fixed counter opposing edge or surface is less than 16”.

4.24 Swing gate entrapment zone: Locations between a moving gate or exposed operator components and a counter opposing edge or surface where entrapment is possible up to 6ft from grade. Such locations occur if during any point in travel.

General requirements for manual gates

Any gate more than 48 inches (1219 mm) in width or more than 84 inches (2134 mm) in height shall meet the requirements of ASTM F1184; shall be installed per manufacturer’s recommendations and shall be designed, constructed, and installed to meet all of the following:

  • Gates shall not fall over more than 45 degrees from a vertical plane when the gate is detached from supporting hardware. SRMC
