| Point of Contact | Flat | Hemisphere |
| The point of contact provides either a large contact area or a very small (point) contact area depending on the shape of the Bumpon product. |  (side view)• Increased load capacity • Better wear resistance |
 (side view)• Increased sound dampening • Increased energy absorption |
| Profile | Low Profile | High Profile |
| The profile is defined by the height and the diameter (or width) of the Bumpon product. |  • Increased load capacity• Less susceptible to being sheared off substrate |
 • Better hear dissipation• Not recommended if sideways shearing is possible |
| Recess | ||
| A recess is not necessary; however, there are several benefits to providing a recess. |  • Provides target area for the Bumpon product during attachment process• Improves adhesion performance: impact absorption and shear strength • Provides neater appearance • Provides uniform location |
