The adjustable sliders are not staying in place. How do I fix this?

Sometimes the adjustable sliders can slip out of place if the strap keepers are not near the adjustment sliders. Once you have the sliders in the desired location, take the strap keeper (the thin black rectangle) and slide it all the way up to the adjustment sliders. This should keep the adjusters in place and keep the straps from loosening. 

This video shows how to accomplish the necessary adjustments.
