Zusammenfassung:	An angularly adjustable tubular elbow is provided for use in association with an electrical junction box. The elbow has an externally screw threaded male spigot at one end and a correspondingly screw threaded female socket at the other end. A locknut cooperates with the screw thread on the male spigot so as to leave usable screw thread on the male spigot that has a length at least equal to one thread pitch longer than is required for satisfying a specification or requirement. A seal that accommodates rotation of the elbow about the axis of the spigot is provided between the male spigot and the locknut to prevent ingress of moisture or other unwanted fluids along the thread. The elbow can be installed with the locknut fully retracted, followed by rotation of the elbow by no more than 360° to align the female socket and subsequently tightening the locknut.
