ABSTRACT:
A conduit hanger includes an inverted U-shaped bracket having laterally spaced depending legs swingable supporting at their bottoms closure arms. The closure arms are swingably between a closed position extending toward each other and gravity urged toward such position and being urged upward under pressure to an open position providing bottom access between the bracket legs. One or both closure arms may be provided with openings proximate their inner ends and the other arms may be provided with depending legs for engaging a respective opening. In another form, a closure arm projects through an opening in one bracket leg toward the other and is pivotted at its outer end to the bottom of a link whose top is pivotted to the upper outer face of the bracket leg.
