opposing gate posts defining openings in which respective distal ends of the rails are pivotally secured,
whereby the rackable gate during installation in a fence over a terrain is adjustable to the slope of a portion of the terrain by moving opposing ends of the gate panel in opposing directions transverse to a longitudinal axis of the rails while the pickets remain substantially perpendicular to horizontal and the fastening of the second picket on the second edge opposing the fastening of the first pickets on the first edge restrict the rails from pivoting laterally away from the first and second pickets.
10. The rackable gate as recited in claim 9, wherein the fasteners attaching the first and second pickets to the rails at the respective first and second edges comprise flexible mild steel welds.
11. The rackable gate as recited in claim 10, wherein the angle at which the rails are disposed is between about 0 degrees and 60 degrees.
12. The rackable gate as recited in claim 11, wherein the gate panel is selectively racked during installation between about 0 and 20 degrees relative to the angle at which the rails are disposed when the rails and pickets are initially attached together.
13. The fence panel as recited in claim 10, wherein the rails are four-wall tubular members.
14. A method of making a gate for tracking a sloped grade during installation of a fence over a terrain, comprising the steps of:
(a) disposing a first rail parallel and spaced-apart from a second rail at an angle to a horizontal plane to define a longitudinal length of a fence panel, the rails each defining a lateral side surface having opposing first and second side edges spaced-apart thereof
(b) sitting a plurality of first pickets onto the lateral side surface of the rails substantially perpendicular to the horizontal plane;
(c) attaching the first pickets thereto with a fastener only between the first pickets and the first side edge of the rails;
(d) sitting a second picket onto the lateral side surface of the rails substantially perpendicular to the horizontal plane
(e) attaching the second picket thereto with a fastener only between the second picket and the second side edge of the rails; and
(f) pivotally securing distal ends of the rails to opposing posts, whereby the gate, being racked by moving the opposing posts in opposing directions transverse to a longitudinal axis of the rails, conforms the slope of the rails substantially to the slope of the portion of the terrain by changing the angle between the pickets and the rails in a plane defined by the lateral side surface of the rails while the pickets remain substantially perpendicular to horizontal and the fastening of the second picket on the second edge opposing the fastening of the first pickets on the first edge restrict the rails from pivoting laterally from the pickets.
