Here is something I am sure alot of people could use for mounting fans on a radiator,top of a chassis or anyware.
I found this in my garage while scratching for bits for my next mod.It is a trailer light mounting bracket.
Two 120 mm fans fit perfectly.
I bought it at Midas Auto in South Africa but I am sure you could find something similar where you stay.
For South African's there is a pic. of the tag.PRICE R 24.95 ,priced today because Ineed to more.
