1. An electrical box comprising: an integral conduit receiving port;a weatherproof fitting to be positioned against a shoulder in the integral conduit receiving port;a conduit retention device having a bottom portion to be positioned against the weatherproof fitting and a top portion having a plurality of first teeth and a plurality of second teeth, wherein the plurality of first teeth extend a first distance toward a center of the conduit receiving port at an angle toward the bottom portion of the conduit retention device, wherein the plurality of second teeth extend a second distance toward a center of the conduit receiving port at an angle toward the bottom portion of the conduit retention device, and wherein the first distance is less than the second distance, such that the plurality of second teeth are capable of engaging conduits having a first outside diameter, and the plurality of first teeth and the plurality of second teeth are capable of engaging conduits having a second outside diameter; anda cap device to be positioned against the conduit retention device for retaining the weatherproof fitting and the conduit retention device in the integral conduit receiving port. 2. The electrical box of claim 1, wherein the integral conduit receiving port is formed in-situ in the electrical box. 3. The electrical box of claim 2, further comprising at least two integral conduit receiving ports. 4. The electrical box of claim 1, wherein the conduit retention device is permanently installed in the integral conduit receiving port. 5. The electrical box of claim 1, wherein the conduit retention device is removably installed in the integral conduit receiving port using the cap device. 6. The electrical box of claim 5, wherein the cap device comprises a cap nut threaded to engage a threaded portion of the integral conduit receiving port. 7. The electrical box of claim 1, wherein the integral conduit receiving port comprises: a first inner shoulder for engaging a conduit having the first outside diameter; anda second inner shoulder having a greater inside diameter than the first inner shoulder for engaging a conduit having the second outside diameter. 8. The electrical box of claim 1, wherein the weatherproof fitting comprises an O-ring. 9. The electrical box of claim 1, wherein the weatherproof fitting comprises a gasket having a relatively flat, open-ended cylindrical shape with a top flange of a first opening with a first inside diameter and a bottom flange having a second opening with a second inside diameter that is smaller than the first inside diameter. 10. The electrical box of claim 1, wherein the conduit retention device comprises a spring steel jaw ring. 11. The electrical box of claim 1, wherein the conduit retention device comprises a spring steel jaw ring having the plurality of first teeth and the plurality of second teeth, wherein each of the plurality of first teeth having a length selected from at least a first length suitable for engaging a first conduit having a first outside diameter, and wherein each of the plurality of second teeth having a second length that is different from the first length and that is suitable for engaging a second conduit having a second outside diameter that is different from the first outside diameter of the first conduit. 12. The electrical box of claim 11, further comprising a tool for removing conduit held in place by the conduit retention device, the tool comprising, a tube having an inner diameter substantially similar to an outer diameter of a conduit to be removed and an outer diameter smaller than an inner diameter of the conduit receiving port, the tube slipping around the conduit after it has been installed and slipping into a gap between the conduit and the conduit receiving port for separating the plurality of teeth of the spring steel jaw from the conduit. 13. The electrical box of claim 1, wherein the electrical box is formed from a material selected from at least one of steel, aluminum and plastic. 14. A plastic electrical box comprising: an integral conduit receiving port formed in-situ in the plastic electrical box;a weatherproof fitting to be positioned against a shoulder in the integral conduit receiving port;a seat ring to be positioned against the weatherproof fitting for maintaining the weatherproof fitting in position in the integral conduit receiving port;a conduit retention device to be positioned against the seat ring and having a plurality of first teeth and a plurality of second teeth, wherein the plurality of first teeth extend a first distance toward a center of the conduit receiving port at an angle toward the seat ring, wherein the plurality of second teeth extend a second distance toward a center of the conduit receiving port at an angle toward the seat ring, and wherein the first distance is less than the second distance, such that the plurality of second teeth are capable of engaging conduits having a first outside diameter, and the plurality of first teeth and the plurality of second teeth are capable of engaging conduits having a second outside diameter that is greater than the first diameter; anda cap device to be positioned against the conduit retention device for retaining the weatherproof fitting, the conduit retention device and the seat ring in the integral conduit receiving port. 15.
