Hand Strap and Shoulder Strap
There are four metal cleats, one on each corner of the Allegro CE case.
Each cleat has two metal rings that are used to attach the hand strap
and shoulder strap onto the Allegro.
The straps can be attached in numerous configurations, depending
on your preference and whether you are right-handed or left-handed.
The shoulder strap can be used as a neck strap for hands-free
operation. The tension on the hand strap is adjustable.
