40mm fan duct designed to mount to a standard 40mm fan and get to suck from or blow where you want it to.

There are 3 mounting options as 40mm fans are not so standard in the size of the mounting holes, whereas the spacing is mostly standard.
 
'M3 BOLT MOUNT OPTION': Small fan holes that don't easily pass a #6-32 bolt or you want to mount the fan into threading on the other side of the duct. You will need your own bolts.

'SELF TAPPING MOUNT OPTION': please look at 4th photo carefully.  Comes with 4x #8x1/4'' self-tapping screws.

'GLUE MOUNT OPTION': Other times there's a metal grill in the way or you just want to superglue and be done with it.

Note, if you use self-tapping option it is highly recommended you start the threading into the duct first while laying it flat on a table and making sure you screw straight. Then, pick up the duct with the screws stuck in it and hold it against the fan and screw all the way.


PLEASE CHECK TECHNICAL DRAWING TO ASSURE FIT.
COMES ONLY AS SHOWN - ONE (1) FAN DUCT;
SELF TAPPING OPTION COMES WITH 4 SELF TAPPING SCREWS (4X #8x1/4'') .
