J-hooks with a multi clip or "bat wing" as they are some times called find their use in several applications. The multi clip will grab on to ceiling grid wire as well as 1/4" threaded rod. (I have seen them used on 3/8" rod but it is a stretch!). One of my favorite arguments for bat wing j hooks is in retrofit applications. Let's say you have installed a run of cable using your own threaded rod or grid wires. If your customer asks you to add a run, maybe a security bundle, you can simply clip a j hook on to your hanger and your are good to go. These j hook with bat wings also makes quick work of multiple j hook assemblies. Simply mount your rod and clip on you j hooks with out having to spin on extra hardware.
