Abstract
A swivel drop ear elbow fitting includes a threaded nut, a retaining ring, and a hollow elbow adapter. The threaded nut includes a plurality of integrated attachment ears located along an external periphery of the threaded nut. An outer surface of the first portion of the elbow adapter is shaped to receive the retaining ring, which retains the threaded nut on the first portion of the elbow adapter, while allowing the hollow elbow adapter to rotate with respect to the threaded nut.
Claims20
A swivel drop ear elbow fitting, comprising:
- a threaded nut including one of a plurality of integrated attachment ears and an integrated mounting ring located along an external periphery of the threaded nut, wherein each of the attachment ears when implemented includes an aperture for receiving a fastener for securing the threaded nut to a stationary support, and wherein the mounting ring when implemented includes a plurality of mounting holes;
- a retaining ring;
- and
- a hollow elbow adapter including a first portion centrally positioned with respect to a first axis and a second portion centrally positioned with respect to a second axis, wherein the second axis is not colinear with the first axis, and wherein an outer surface of the first portion of the elbow adapter is shaped to receive the retaining ring which retains the threaded nut on the first portion of the hollow elbow adapter while allowing the hollow elbow adapter to rotate with respect to the threaded nut.
