Title: Wire guide bushing and method of production

Abstract: A wire guide bushing includes a thin-walled nylon tube which is outwardly flared at its proximal end, the border of the flared portion being folded forwardly to overly the flared portion outer face and form a double thickness wall. The tube is peripherally outwardly bulged shortly forwardly of the flared portion and the bushing is applied merely by inserting the bushing in a panel opening and forcing it past the bulge to embrace the opening border between the peripheral bulge and flared portion. In producing the guide bushing the tube is partially nested in a well in a block with the flared portion outermost and a tool with a cylindrical shank and an enlarged head with a concave underface is inserted in the tube and pressed downwardly against the flared portion edge to outwardly peripherally bulge the tube between the block and flared portion.
