ABSTRACT:
The adjustable sprinkler riser includes an outer and an inner telescoping member that telescopically interface with each other. A protrusion is spaced from a proximal end of the outer telescoping member. A first joint member slidably interfaces with the outer telescoping member, and a second joint member slidably interfaces with the inner telescoping member. The second joint member may be selectively secured to the first joint member to restrict movement of the inner telescoping member relative to the outer telescoping member. In such a condition, areas of vulnerability to breakage in the joint members and inner telescoping member are offset from each other to provide greater strength to the adjustable sprinkler riser. In addition, manufacturing the adjustable sprinkler riser is simple because the first and second joint members may be conveniently placed on the telescoping members, and there is no need to form threads or other intricate structures on the telescoping members.
