and a clamp assembly comprising: a clamp ring; and a plurality of clamps each comprising a longitudinal portion and a claw, the longitudinal portion extending longitudinally from the clamp ring, and the claw extending transversely and inwardly from the longitudinal portion, wherein each of the plurality of clamps is sized to be received in one of the plurality of first sloped recesses. ### Claim 2 (depends on 1) The condulet assembly of claim 1, wherein a number of the plurality of first sloped recesses is even and each of the plurality of first sloped recesses is positioned symmetrically to one of the plurality of first sloped recesses relative to a longitudinal axis of the mouth. ### Claim 3 (depends on 1) The condulet assembly of claim 1, wherein the claw includes serrations at an end of the claw. ### Claim 4 (depends on 1) The condulet assembly of claim 1, wherein the longitudinal portion of one of the plurality of clamps further includes a flap having a first end and a second end opposite the first end, the flap extending from the longitudinal portion at the first end of the flap outwards and away from the longitudinal portion. ### Claim 5 (depends on 4) The condulet assembly of claim 4, wherein the mouth wall further includes a plurality of second sloped recesses positioned circumferentially in the interior of the mouth wall, each of the plurality of second sloped recesses including a second slope that has a first end and a raised end being raised relative to the first end, the raised end positioned opposite the first end and more distal to the rim than the first end, one of the plurality of second sloped recesses sized to receive the flap therein. ### Claim 6 (depends on 1) The condulet assembly of claim 1, further comprising a first gasket sized to be received in the clamp assembly. ### Claim 7 (depends on 1) The condulet assembly of claim 1, further comprising a guide ring sized to be positioned around the rim of the mouth. ### Claim 8 (depends on 1) The condulet assembly of claim 1, wherein the condulet assembly is sized to connect with a rigid metal conduit and an intermediate metal conduit of the same trade size. ### Claim 9 (depends on 1) The condulet assembly of claim 1, wherein at least one of the plurality of clamps extends away from the clamp ring and toward the rim of the mouth. ### Claim 10 A method of fabricating a metal conduit raceway of an electrical system, comprising: providing a rigid or intermediate metal conduit and a condulet assembly, the condulet assembly including a condulet sized to receive the conduit, the condulet including: a condulet body; and a mouth including a mouth wall extending from the condulet body and forming a rim of the mouth, wherein the mouth wall further comprises a plurality of first sloped recesses circumferentially positioned in an interior of the mouth wall, each of the plurality of first sloped recesses including a first slope that has a first end and a raised end being raised relative to the first end, the raised end positioned opposite the first end and more distal to the rim than the first end; assembling the condulet assembly by positioning a clamp assembly inside the mouth, wherein the clamp assembly includes: a clamp ring; and a plurality of clamps each including a longitudinal portion and a claw, the longitudinal portion extending longitudinally from the clamp ring, and the claw extending transversely and inwardly from the longitudinal portion, wherein each of the plurality of clamps is sized to be received in one of the plurality of first sloped recesses; inserting the conduit into the mouth of the condulet; and pushing the conduit into the condulet until one of the plurality of clamps is disposed in one of the plurality of first sloped recesses. ### Claim 11 (depends on 10) The method of claim 10, wherein pushing the conduit further comprises pushing the conduit into the condulet until a first click is produced by the one of the plurality of clamps being disposed in the one of the plurality of first sloped recesses. ### Claim 12 (depends on 10) The method of claim 10, wherein the longitudinal portion of one of the plurality of clamps further includes a flap having a first end and a second end opposite the first end, the flap extending from the longitudinal portion at the first end of the flap outwards and away from the longitudinal portion. ### Claim 13 (depends on 12) The method of claim 12, wherein the mouth wall further includes a plurality of second sloped recesses positioned circumferentially in the interior of the mouth wall, each of the plurality of second sloped recesses including a second slope that has a first end and a raised end being raised relative to the first end, the raised end positioned opposite the first end and more distal to the rim than the first end, one of the plurality of second sloped recesses sized to receive the flap therein, and pushing the conduit further comprises pushing the conduit further into the condulet until the flap is disposed in one of the plurality of second sloped recesses. ### Claim 14 (depends on 13) The method of claim 13, wherein pushing the conduit further comprises: pushing the conduit further into the condulet until a second click is produced by the flap being disposed in the one of the plurality of second sloped recesses. ### Claim 15 (depends on 10) The method of claim 10, wherein assembling the condulet assembly further comprises positioning a first gasket in the clamp assembly. ### Claim 16 (depends on 10) The method of claim 10, wherein assembling the condulet assembly further comprises positioning a second gasket inside the mouth before positioning the clamp assembly inside the mouth. ### Claim 17 (depends on 10) The method of claim 10, wherein assembling the condulet assembly further comprises positioning a guide ring around the rim of the mouth, and inserting the conduit further comprises inserting the conduit into the condulet by sliding the conduit along an interior of the guide ring. ### Claim 18 (depends on 10) The method of claim 10, wherein the claw includes serrations at an end of the claw. ### Claim 19 (depends on 10) The method of claim 10, wherein a number of the plurality of first sloped recesses is even and each of the plurality of first sloped recesses is positioned symmetrically to one of the plurality of first sloped recesses relative to a longitudinal axis of the mouth. ### Claim 20 (depends on 10) The method of claim 10, wherein the condulet assembly is sized to connect with a rigid metal conduit and an intermediate metal conduit of the same trade.
