Abstract
A multiple layer suction holder is disclosed in which a lower attaching layer is made of a soft, flexible material having a neck extending therefrom. A shell is fitted on top of the lower attaching layer where the shell is made from a flexible material which is harder than the soft, flexible material of the lower attaching layer. The suction holder is further provided with connecting devices which force the shell against the lower attaching layer in order to provide an internal pressure in the lower attaching layer directed toward the mounting surface. Hence, air cannot readily pass under the lower attaching layer. The multiple layer suction holder provides maximum contact with the mounting surface and maximum memory that results in longer life of the suction holder.
