How to build the Internal frame pack from the "Full Modular Pack" or the "Hunter Pack"
First remove the gray (Comp "A" or "B") and black (Comp "D") compartment from the Frame, if necessary, unzip from the burgundy (comp "C") compartment. Remove the shoulder harness from the frame by sliding the three top straps completely out of the buckles. The bottom strap is detached by unsnapping the snap from the frame at the very bottom. Remove the hip belt from the frame by removing the 1 inch straps from the ladderlocks on each side of the frame and unsnap the 2 bungee cords from the back of the belt. Finally remove the one inch stays (bars) from the frame. (be sure to replace the thumb screws back to the frame so you don't lose them.)
To assemble the internal frame pack, first zip the gray compartment to the black compartment, with both zippers. Then slide the frame stays into the black sleeves, as illustrated, with the holes at the bottom towards the user's back. Next remove the white thumb screws (3 &4) from the back of the hipbelt and thread them through the brass grommet from the front of the black compartment though the hole in the stay and back into the hipbelt as illustrated above! Next attach the side load control straps off the hipbelt to the top buckle of the black compartment and tighten.
To attach the shoulder straps, thread the two inch strap down through the ladders in the back of the gray compartment, tighten, then thread into buckets behind the pad at the bottom. The top load control buckles go into their respective buckles at the top. Finally , snap the bottom of shoulder strap into the top grommet of the black compartment.
To get to the day and fanny pack from this point, just divide the gray compartment
from the black compartment and remove the stays. Replace the thumb screws back
into the hipbelt from the front of the black compartment. Finally , move the
snap from the bottom of the shoulder strap up to the bottom grommet of the gray
