    • A barrier is formed from at least one elongate rail and at least one vertica upright member. The elongate rail includes a web and a pair of opposed side wall which extend from the web to define a rail channel. Each upright member includes a aperture formed therein. In one implementation, a pin extending from a clip i inserted into the aperture, and the upright member, with the clip, is at least partiall situated within the rail channel, wherein the clip is welded to an inside surface of the rail channel. In another implementation, a pin is inserted through the aperture, and the upright member, with the pin, is at least partially situated within the rail channel, wherein opposed ends of the pin are welded to an inside surface of the opposed side walls of the rail channel. The pin and aperture form a pivot point allowing the upright member to rotate with respect to the elongate rail. In a fence implementation, this allows the barrier to be racked in order to follow undulating terrain.
    • 屏障由至少一个细长导轨和至少一个垂直直立构件形成。 细长导轨包括腹板和一对相对的侧壁,其从腹板延伸以限定轨道通道。 每个直立构件包括形成在其中的孔。 在一个实施方案中,从插入孔中的夹子I延伸的销以及夹子的直立构件至少部分位于轨道通道内,其中夹子焊接到轨道通道的内表面。 在另一种实施方式中,销穿过孔插入,并且具有销的直立构件至少部分地位于轨道通道内,其中销的相对端焊接到相对侧壁的内表面 铁路通道。 销和孔形成允许直立构件相对于细长轨道旋转的枢转点。 在围栏实施中,这允许障碍物被搁置,以便跟随起伏的地形。
