Ideal for use with smaller cylinders, the Narrow Nitrox Decal is { 17 in x 1.5 in | 43 cm x 4 cm } and consists of two { 0.25 in | 0.6 cm } yellow outer bands with NITROX in green letters and a { 1 in | 2.5 cm } green center band with NITROX in yellow letters and can be used on any color tank to identify Nitrox. The thinner, smaller design is easier to place, and means less possibility of corrosion underneath the decal.
