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.
