First thing to do is to open up the tripod's legs a bit in order to strap them down properly.



Next, flip the tripod upside-down, and place onto the backpack's outward side so that the top of the tripod is at the bottom of the bag.

(CAUTION: having the tripod upside-down leaves the top end of the tripod exposed. BE CAREFUL when laying down the backpack after the tripod is installed.)



Start loosening off the straps on the backpack, and wrap the bottom strap around the bottom of the tripod.



Once both bottoms are in, move to the mids and do them up as well.



After the mids are in, you must install the spacer.



After installing the spacer, expand the other 2 legs of the tripod up enough so the upper straps are able to lock the top of the legs up.



Once all the straps are clipped and tightened, you can move on to the last step.
