BI-DIMENSIONAL FOLDING INSULATOR

摘要

An insulator comprises at least three sections hingedly connected to one another, including a center section and a pair of outer sections. The sections are shaped so that if the outer sections are folded in a first direction relative to the center section, the insulator can be used with a first tube of a first diameter, and if the outer sections are folded in a second direction relative to the center section the insulator can be used on second tube of a different diameter from the first diameter.
