The frame is fabricated from aluminum alloy extrusions with primary members (top and bottom) "P" shaped in cross section. Vertical members at the ends of the frame are square in cross section with nominal base dimensions of no less than 2"x2".
The gate frame is reinforced or post-tensioned with 1.66" OD X 0.055" wall, galvanized steel tubing. This tubing runs continuously through the full length of the top and bottom horizontal primary members.
The gate frame is supported from the track of extruded aluminum alloy by two self aligning, 4-wheeled, sealed lubricant, ball-bearing truck assemblies. The bottoms of the support posts are equipped with two pairs of rubber guide wheels.
