The rotating collar lets the body turn so the vent stays upright, allowing installation on horizontal or vertical piping. Union connections simplify installation and future service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore ordering:\u003c\/strong\u003e Check that the 1\" sweat union connection matches your piping.
