This dedicated 72mm Tamron Petal-Style Lens Hood is specifically designed for use with the AF 18-270mm f/3.5-6.3 Di II VC and SP AF 17-50mm f/2.8 XR Di II VC LD Aspherical (IF) lenses.
Lens hoods are primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact.
The "petal" shape of this lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area. This dedicated lens hood is designed to match the specific focal length of the lens it was designed for.
