Protective fittings for tubular conduit are provided herein. An exemplary protective fitting includes a substantially tubular body sized such that an outer peripheral surface of the tubular body is configured to frictionally contact at least a portion of the threaded inner surface of the tubular conduit to releaseably secure the substantially tubular body to the terminal end of the tubular conduit when the substantially tubular body is inserted therein, and a flange extending from the outer peripheral surface of the terminal end of the substantially tubular body. The protective fitting prevents wiring extending from the terminal end of the tubular conduit from contacting the peripheral edge of the terminal end of the tubular conduit.

1. A protective fitting for low voltage electrical conduit, the low voltage electrical conduit having a substantially threaded inner surface and a terminal end defining a peripheral edge, the protective fitting comprising: a substantially tubular body sized such that an outer peripheral surface of the tubular body is configured to frictionally contact at least a portion of the threaded inner surface of the low voltage electrical conduit to releaseably secure the substantially tubular body to the terminal end of the low voltage electrical conduit when the substantially tubular body is inserted therein, the tubular body having open opposing terminal ends, the outer peripheral surface comprising a threaded outer surface having a thread pattern consisting of two sidewalls extending normally from the tubular body and in spaced apart relationship to one another and a convex portion extending between the sidewalls such that the tubular body is configured to mate with a helically wrapped, loosely interlocked strip forming the low voltage electrical conduit;a plurality of protrusions disposed between the two sidewalls of the thread pattern, the plurality of protrusions extending in a helical pattern around the outer peripheral surface;a flange extending from the outer peripheral surface of at least one of the terminal ends of the substantially tubular body; andwherein when the protective fitting is inserted with the terminal end of the low voltage electrical conduit, the protective fitting is capable of preventing wiring extending from the at least one of the terminal ends having the flange from contacting the peripheral edge of the terminal end of the low voltage electrical conduit. 2. The protective fitting of claim 1, wherein an intersection point formed between an inner surface of the tubular body and an outer surface of the flange is rounded. 3. The protective fitting of claim 1, wherein an intersection point formed between an inner surface of the tubular body and an outer surface of the flange is chamfered. 4. A protective fitting for tubular conduit, the tubular conduit having substantially threaded inner and outer surfaces and a terminal end defining a peripheral edge, the tubular conduit having at least one wire extending therethrough and at least partially from the terminal end of the tubular conduit, the protective fitting consisting of: a substantially tubular body having a threaded inner and outer surface configured to matingly cooperate with at least one of the threaded inner and outer surfaces of the tubular conduit to releaseably secure the substantially tubular body to the terminal end of the tubular conduit when the substantially tubular body is threadably engaged therewith, the tubular body having open opposing terminal ends, the substantially tubular body further comprising a plurality of protrusions being disposed extending in a helical pattern around the outer peripheral surface, wherein each of the plurality of protrusions is a circular dome extending outwardly from the outer peripheral surface;a flange extending from the outer surface of at least one of the terminal ends of the substantially tubular body;wherein when the protective fitting is threadably engaged with the terminal end of the tubular conduit, the flange covers the peripheral edge of the terminal end of the tubular conduit, and the flange is capable of preventing the at least one wire extending from contacting the peripheral edge of the tubular conduit; andwherein the protective fitting is fabricated from a polymeric material. 5. The protective fitting of claim 4, wherein an intersection point formed between the inner surface of the tubular body and an outer surface of the flange is rounded. 6. The protective fitting of claim 4, wherein an intersection point formed between the inner surface of the tubular body and an outer surface of the flange is chamfered. 7. A protective tubular insert for low voltage electrical conduit, the low voltage electrical conduit consisting of a threaded inner surface and a terminal end defining a peripheral edge, the low voltage electrical conduit configured to allow at least one wire to extend therethrough and at least partially from the terminal end of the low voltage electrical conduit, the protective tubular insert having an at least partially threaded outer surface configured to matingly cooperate with the threaded inner surface of the low voltage electrical conduit to releaseably secure the substantially tubular body to the terminal end of the low voltage electrical conduit when the substantially tubular body is threadably inserted therein and a flange extending outwardly from the outer surface of the terminal end of the substantially tubular body; wherein when the protective fitting is threadably inserted into the terminal end of the low voltage electrical conduit, the flange covers the peripheral edge of the terminal end of the low voltage electrical conduit; and wherein the protective fitting is fabricated from a polymeric material, wherein the at least partially threaded outer surface includes a thread having two sidewalls extending normally from tubular body and in spaced apart relationship to one another and a convex portion extending between the sidewalls. 8. The protective fitting of claim 7, wherein an intersection point formed between an inner surface of the tubular body and an outer surface of the flange is rounded. 9. The protective fitting of claim 7, wherein an intersection point formed between an inner surface of the tubular body and an outer surface of the flange is chamfered.
