A versatile swivel fitting, useful for awkward applications where angles cannot be accommodated by adjustable angle fittings. The assembly is riveted together, although items can be supplied separately as 167M and 2 x 173F. The through tube (vertical in photo) cannot be joined within the fitting.
(See clamp 167M). (See clamp 173).
Warning: To provide sufficient stability, whole structures must not be made from swivel fittings alone.
