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
- If you need to mount your 3/4″ j hook directly to the ceiling, a couple of set ups are available to you. If you are fastening to wood or a metal deck, simply use a 3/4″ j hook with an angle bracket attached, select the appropriate screw and drive up with your driver. If you have a concrete deck, you can use a Tapcon anchor or a 3/4″ j hook with a nail installed for use in a Hilti, Ramset and other powder actuated tools.
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.
