Abstract: A housing for an electrical wiring device includes an adjustable clamping mechanism for retaining electrical conduits therein. The clamping mechanism has a pair of opposing strain relief members on opposite sides of a conduit passageway, set to accept a predetermined conduit width. Each strain relief member has a frangible portion which can be removed by a user. In this manner, if a user desires to retain, by means of an interference fit, a conduit having a diameter larger than the predetermined spacing of the intact strain relief members will allow, one or both frangible portions can be removed to accommodate a larger sized conduit. Alternatively, more than one pair of strain relief members having frangible portions can be alternately arranged to clamp a conduit in an S-shaped configuration, capable of accepting multiple conduit sizes by removing some or all of the frangible portions.
