One the most common hangers used in structured wiring applications, especially in security cabling where small cable runs are common is the 3/4″ j hook. A variety of configurations are available to facilitate most any application.
Standard 3/4″ J Hooks
- For your basic wall runs, the standard j hook works well. Depending on the wall, they can be mounted with a variety of screws and small concrete anchors. For concrete walls, they can often be shot on with a Hilti or Ramset type of tool.
3/4″ J Hooks With Hammer On Clamps
- Many open warehouses have a bar joist type ceiling. Using a 3/4″ j hook with a hammer on clamp makes for quick installations. Most of these bar joists have a flange around 3/16″ of an inch. If you have an I beam, you will need a thicker hammer on clamp. Also check for a manufacture that offers the j hook set up to rotate 360 degrees so you can run any direction on the bar joist.
Multi-Clip 3/4″ J Hooks
- 3/4″ j hooks with multi clips or bat wings as some call them area designed to grab on to ceiling grid wire, pencil rod and all thread up to 1/4″. Simply squeeze the clip and position at desired height. Make sure to follow codes as to whose grid wire you are clamping on to!
3/4″ J Hooks For Mounting To The Ceiling
Keep a variety of 3/4″ j hooks in stock and you will be able to handle any situation you run into in the field without spending time shopping for individual components to get the job done.
Ramset Replacement Parts
Keeping a few basic replacement parts on hand for your Ramset powder actuated tool will keep your job running. With just a few of the basic wear parts on hand, you will be able to handle simple jobsite repairs. The most common of any Ramset replacement parts to keep on hand is the piston or drive pin. This is the part that drives the pin into the concrete so it takes the most abuse. Replacement of the piston in your tool is usually very straight forward and takes just a few minutes, if you have one! Cost on the piston for most tools is usually under $40. Some tools like the Ramset Cobra (a clone of the Hilti DX-350 tool) and the D-60 use a barrel clip to hold the front and rear barrel together. These can get tweaked from over driving so have a couple on hand. One last part I would recommend to have on hand is the return pawl. The purpose of this piece is to reset the piston in the chamber for the next shot. The return pawls on the Ramset Viper and D45A are small and can get lost easily, again having a couple on hand will keep you going. Keep in mind as well that if you need to order a part, make sure of your tool model especially in the case of the Ramset Cobra tool and the Ramset Cobra Plus tool as the pistons are not interchangeable! Ordering extra parts like two pistons instead of one will reduce your over all shipping charges.

Shoot Up J Hooks With Your Hilti & Ramset Tools!
be the fastest way to install data cable to a concrete deck. Available in both 3/4″ and 2″ sizes these UL listed j hooks offer the support and flexability you need for your cable runs. We use a ballistic point pin ceiling clip for a better success rate even in hard concrete ceilings. These pins work in most Hilti, Ramset, Simpson, Powers and other powder actuated tool.

While shooting pre tied ceiling clips to a concrete ceiling is one of the fastest ways to suspend grid wire or pencil rod, there are times when you are not allowed to shoot by the management of the facility or because of the make up of the concrete. In this application, using a tie wire wedge anchor will fit the bill nicely. A tie wire wedge anchor is very similar to a standard wedge anchor that you would use to bolt racks and other equipment to a poured concrete floor. Instead of a threaded stud, you are left with an eye that you can fasten jack chain or ceiling grid wire to. Installation is simple, just drill a 1/4″ hole, hammer in the tie wire wedge and give a tug. One advantage a tie wire wedge anchor offers over shooting is more holding power and a sure set every time. Tie wire wedge anchors are available pre tied with to both 4′ and 6′ ceiling grid wire. With our ODM overhead drill machine, you now have the luxury of installing these anchors from the floor! Check out the video at our site. Next time you can’t use your Ramset or Hilti tool for shooting up grid wire, check out the easy to use tie wire wedge anchor.
J Hooks with bat wings are one of the most common types of j hooks used for data cabling. The bat wings as they are called are clips that will mount on to pencil rod, ceiling grid wire, 1/4″ all thread and smooth rod. While they will clip on to 3/8″ all thread with a little effort, not all j hooks with bat wings show data for these applications. This usually isn’t a real issue as the loads are usually quite low. While clipping on to existing ceiling grid supports is a no no, j hooks with bat wings still have many applications. You can shoot up your own ceiling wire and clip and add on j hooks at different heights for different runs. Shooter clips are also available with 1/4″ all thread installed which work perfect in situations where you are not allowed to hang on a grid wire or where you would want to have more of a rigid install. Simply shoot in the rod and add you j hooks with bat wings at the desired level. J hooks with bat wings are available in sizes ranging from 3/4″ to 4″. Check out our j hooks with bat wings along with a wide variety of data cable hangers online.
Check out the brief video below for some installation ideas when you are using bridle rings. While bridle rings may not be the data cable hanger of choice for data sensitive cable, for many simple wire applications they still fit the bill. The fastest way to install a bridle ring to concrete is with our shooter clip designed for use in Hilti, Ramset and other powder actuated tools. Not shown in the video are the Sammy Super Screws which make for easy install of bridle rings in metal decking and wood.
When ceiling grid wire hangers or pencil rod doesn’t offer enough rigidity or code won’t allow you to use a ceiling grid wire to support your hangers, consider our SC14 shooter rod hangers. The SC14 shooter rods are designed for use in Ramset, Hilti, Powers, Simpson and other powder actuated tools. Available with in lengths from 12″ to 36″ these hangers lend themselves to many install applications. Use them with an Arlington Loop or j hooks for fast cable hanger installs. One very common install involves mounting a j hook or loop at the bottom and then adding a second j hook or loop with a mutli clip midway up the rod. These can be assembled on the floor and installed with a powder tool on an extension pole.
Many electricians are using them for their BX cable runs. Simple shoot in and fasten your BX cable with a clip like the Caddy KX clip. Simple to use, open the box and shoot! The uses for these shooter clips are endless.

Drop in anchors are a common anchor in most trades for fastening to solid concrete. For most applications the standard length drop in type anchor works well. However there are situations that require shallow embedment or mini drop in anchors. The most likely situation is post tension concrete. Fastening to post tension concrete requires caution due to the tensioned cable below the surface. Most situations allow you to drill up to 3/4″, ruling out standard drop in anchors. Shallow embedment or mini drop in anchors are available in 1/4″, 3/8″ and 1/2″ sizes. These anchors will fully set at 3/4″ embedment making them a great choice when you are limited in drill depth. It is recommended that you use what is called a stop bit while drilling for these anchors. These bits have a collar on them preventing them from drilling the hole deeper than allowed. These bits are actually a great time saver in that they prevent you from drilling your hole deeper than necessary. If you over drill your anchor hole by just a quarter of an inch, that would mean you are drilling the equivalent of one extra hole every 3 holes! If you are using a cordless SDS rotary hammer, this can drop your hole count per charge by 25%. These bits are also available for you standard drop in anchors as well. As a contractor it is your responsibility to make sure you are allowed to drill in the post tension concrete. If 3/4″ drill depth is permitted, then the min drop in or shallow embedment anchor is a great problem solver.
