A one-piece hanger is formed with a pair of spaced segments or legs joined by an end wall. Each segment has a recess formed in an edge which is open towards the recess on an edge of the opposite segment. The two recesses are aligned so as to create a substantially full opening to receive a pipe. The hanger' may be positioned on a pipe with the segments extending substantially parallel to the pipe axis and the hanger can then be rotated about 90° so that the pipe extends through the substantially full opening formed by the recesses. The hanger end is formed with mounting holes.

Why it's free to use
- Filed May 13, 2004 and granted July 17, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 13, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 13, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
