In the past I've had my inline sitting on my tent roof. Well now I'm adding a second light and a carbon filter and would rather not have that much weight resting on the bars. When I got my inline fan it came with mounting bracket, but I can't seem to figure out how to attach the fan to the bracket. There are no screw holes etc to attach one to the other. How do I go about achieving this? Sorry I'm a little new to diy and the use of non-standard tools.
