The actual dimensions for this dome is 3 3/8" diameter and 2 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 3/4 ounce.
