Step 4 - Position the Upper Load Stabilizer Straps
After correctly positioning the Harness Shoulder Straps the exit
point of the Upper Load Stabilizer Straps are the next consideration
in the fitting process.
Before proceeding we must ensure that the Internal Staves
are following the contour of the back, the Hip Belt is now positioned
correctly across the Iliac Crest, and the curve of the Harness Shoulder
Straps is positioned in the centre of the chest.
The exit point of the Upper Load Stabilizer Straps is at the
front of the shoulder, on or just below the collar bone (clavicle).
This pull position of the Upper load Stabilizer Straps can be adjusted
by sliding the 25mm buckle up or down the lower webbing to achieve
The Upper Load Stabilizer Straps pull position at the front of
the shoulder to the fixed position on the backpack should not be
more than a 45 degree angle.
Do not over tension the Upper Load Stabiliser Straps. Over tensioning
and having these straps incorrectly pull at more than 45º from the
exit point on the Harness Shoulder Straps to the anchor point on
the backpack, lifts the Shoulder Straps, renders the Sternum Strap
ineffective and places excessive unnecessary stress on the chest.
