Abstract: A self-locking strut-nut system for securement within a longitudinal constructional rectangular channel includes an element for selectable lockable engagement with the rectangular channel, such element defining a medial plane of the nut system. Such system also includes an element for threadably receipt of a complementally threaded rod, such receipt element having an axis transverse to such medial plane, the receipt element extending in length of the strut-nut system along such axis which exhibits upper and lower ends. The system also includes a rigid planar washer having an aperture. The system additionally includes an element for selectable engagement within the rigid washer, such engagement element extending integrally downwardly from a lowermost plane of the system, co-parallel to the medial plane of the system and transverse to the axis of the receipt element. Accordingly, the washer is secured transversely to the axis of the receipt element and against the lowermost plane of the system.

Abstract: A suspendable conduit bracket system includes a back bracket element defining, in transverse cross-section, an inner semicircle and an outer semicircle of greater radius than the inner semicircle, such semi-circles mutually integrally secured by ribbing elements, the inner semi-circle comprising a nesting element proportioned to the cross-sectional geometry of a conduit to be suspended. The bracket system further includes a radial portion protruding externally from the two semi-circles of the back element, passing through both of the semicircles, and having an element for selectable lockable engagement with a solid rectangular channel, a threaded radial channel extending through substantially the entire radial length of such channel, and proximally to the intersection of the radial portion with the back element, a rigid insert having a deformable aperture is secured transversely to the threaded channel.
