Designed to suspend threaded rod from the Q-Deck. Q-Deck hangers are the quickest, most economical way to hang plumbing pipe, light fixtures, sheet metal duct, display fixtures, and more. Can be used as a pre-insert in concrete when used on top of deck, by threading the rod up 2-1/2″ and adding a hex knot on the rod, where you pour concrete on top of the clip.
