This is perfect for adding a lampholder to your pipework light.
Or maybe a cord grip to use as a cable entry point. The 10mm allthread that is supplied can be removed if you need to add a longer allthread or other fitting.
This product does not come with any cord grips or lampholders.
The pictures are just examples of what you can do.
