Abstract: The present invention is a flexible bridge that positions a strut nut in a C-shaped mounting channel. The flexible bridge is graspable between a thumb and forefinger for rapid positioning, and converts to an anti-rotation device that prevents the strut nut from rotating within the channel. A harness supports the strut nut while a flexure member provides a grippable location to position the harness and strut nut combination at a desired location within the channel. The flexure member remains outside of the channel while the strut nut and harness are disposed within the channel, and at least a portion of the flexure member has a dimension greater than the width of the channel. This dimension prevents the flexible bridge from withdrawing into the channel when the strut nut is in place in the channel. The flexure member converts to an anti-rotation mechanism for preventing the strut nut from rotating within the channel during engagement with the threaded member.
