ABSTRACT:
A cable tray conduit clamp is comprised of a single one-piece body having a 90.degree. sector plate, a square block protruding from one surface thereof with two sides in alignment with the radii of said sector plate and a bevelled boss protruding from the opposite surface of said plate with two sides thereof disposed in alignment with the radii of said sector plate. The extent of said block along the radii of said plate is substantially greater than the extent of said boss along said radii of said plate while the radial extent of said sector plate is substantially greater than the radial extent of said block. A pair of perpendicular intersecting bores are formed through the block and continue outwardly to the curved periphery of the sector plate as open channels in the surface of the plate from which the block protrudes. A J-shaped bolt having a sleeve nut threaded thereon is secured in one of the channels for clamping the body to a flange cable tray. A third bore extends orthogonally to said two intersecting bores through the block, plate and boss and a second J-shaped bolt extends therethrough for clamping various size conduits to the other surface of said plate against the bevelled boss.
