The actual dimensions for this dome is 3 15/16" diameter and 2 3/4 inches tall .
It is formed with .030 PETG plastic , the same stuff soda bottles are made with but much thicker.
It will protect your equipment from a " flip over" but probably not a fall from altitude.
That is just the price we pay for its light weight at 5/8 ounce.
