Any data cable contractor knows what J hooks are. But many are just familiar with the standard J hooks or the ones with the bat wing or multi clip that mounts to grid wire or pencil rod. While these are the most common J hooks, there is a lot more out there.
Start With Size
What sizes to J hooks come in? Well 2″ is by far the most common, did you know that they come in sizes ranging from 3/4″ to 4″? Most outlets carry J hooks in the 2″ and you won’t find out about the other sizes unless they are called out on the print or you ask about them. A 3/4″ unit will costly about half of a 2″ size. The 4″ is a great way to save money on your larger runs without going to a ladder rack or cable tray.
Available Attachments For J Hooks
As mentioned earlier, most are familiar with standard J hooks or the one with the multi clip or bat wing. By the way, that bat wing will grab on 1/4″ rod and I have seen it used on 3/8″ to. These to types of J hooks cover most applications. But there are more options out there. You can get J hooks with Ramset shots to shoot them right to the ceiling, what could be faster than that! You can get them with hammer on flange clips that allow the unit to rotate to any position. They are available with clamps to hook on to the leg of the computer floor for a nice clean installation. If you need to hang the J hooks on threaded rod, simply buy them with an angle bracket installed, get a few nuts and bolts and your are ready to go. Some companies offer custom assemblies built to your specs to speed you along.
What Brand of J hooks?
While Erico Caddy is probably the largest, many others have come on the scene. Some of the generic J hooks offer assemblies the big lines don’t offer. Many of them are now UL listed. I can tell you from experience, these generics work as well and will save you up to 50%. If you haven’t tried the Arlington Loop, can be a great alternative to metal J hooks.
So do yourself a favor and check around for J hooks online and you will find a wide variety that you man not even know existed!
