Using a j-hook mounted to a multi clip or batwing as they are known in the trades is a fast secure way to suspend your cable runs.  We offer j-hooks with bat wings in 3/4″, 2″ and 4″ inch sizes.  J-hooks with bat wings are super easy to install to grid wire, pencil rod and all thread.  They are rated for up to 1/4″ all thread but I have some guys who have used them on 3/8″ in a pinch.  To install, just squeeze the bat wing and position on the rod or wire.  They will grab tight and stay in position for you.  Bat wing j-hooks are especially useful when you want to suspend multiple cable runs on one hanger.  you can space them where you need them.  If you have mounted j hooks with angle brackets on threaded rod before you know it can be time consuming to thread a nut up the rod, place the j hook and then spin another nut up to lock in place.  Now do it two more times!  So yes, j-hooks with bat wings offer a speed advantage.  Another plus is if you need to come back and add another run.  If you already have a suspended support wire in place already, you can just clip another j-hook on and you are good to go.  Below is a short video of our j-hooks with batwings.  you can also find more info and other cable supports on our e-commerce site ConstrucitonFastening.Net
