Abstract
This invention consists of a foldable bushing that may be easily inserted within a hole in a metal framing stud used in the construction of buildings. The bushing may be applied to either holes of regular shapes such as round, square, or rectangular, or to irregular shaped holes. Use of the bushing protects electrical wires that are pulled through the holes within metal framing studs. The bushing is of simple construction, easy to mass produce, and easy to apply. As it may be applied to a wide range of hole shapes and sizes, a minimal number of versions of the bushing satisfy a large variety of applications.

A foldable stud bushing comprising:
- a base portion having a forward edge and an outer edge, an inner periphery and an outer periphery, and a central axis:
- integral fingers extending from said outer periphery of said base portion, said fingers including outer fingers adjacent said outer edge and inner fingers away from said outer edge and situated toward said forward edge;
- a plurality of seats defined by the spaces .between said inner and outer fingers around said outer periphery of said base portion;
- said base portion having two relatively thick walls opposite and parallel to one another with said fingers extending from said relatively thick walls;
- and
- said relatively thick walls being connected to each other by relatively thin walls with said thin walls being without fingers, said thin walls defining a fold area midway along each of said relatively thin walls with said bushing being able to flex around said fold areas when pressure is applied to said outer periphery of said bushing.
