The JJC SCM-1 holder with suction cup has a GoPro standard mount with a mounting adapter with a 1/4" screw. The holder allows you to mount light accessories or a sports camera on flat and smooth surfaces such as: windows, mirrors, tables, etc. Additionally in the box there is an optional self-adhesive base that can be used to stick on all surfaces where the suction cup does not want to stick. The JJC SCM-1 suction cup holder is specially optimized for compatibility with JJC RL-SQ61 and RL-CY96 LED lamps.
