Art. No: EA009-C
This nylon end plug attaches to the upper support bar (+130mm, +230mm & Easyrig STABIL). By guiding the line through the spacing on the plug, you can put the hook in front of the upper support bar to then be able to adjust the slider (EA052). A light or a GoPro (for example) can be attached to the threaded hole.
