A wiring cart for use by electricians is provided whose wire collator outlet from which the wires are drawn is adjustable relative to the position of the conduit opening through which the wires are to be pulled. Such adjustability is provided in one embodiment by adjustable legs that vary the height of at least one end of wire cart. The frame of the wire cart is constructed to allow the cart to be stood on end to aid in the installation of wires through a junction box or in overhead installations. Adjustable wall spacers may also be included to provide a fixed relative positioning relative to the wall. Modular expansion of the number of spools from which wire may be pulled is also provided by stacking, vertically or horizontally, a number of such wire carts. Portability is facilitated by wheels on which the wire cart may be rolled.

1. A wire cart for use in wire pulling operations whereby an electrician pulls wire through a conduit outlet mounted on a wall and attached conduit to wire a structure, the wire being initially stored on spools, comprising:a frame having a first and a second end;a number of spool support rods removably supported at either end thereof by the frame, the rods having a diameter adapted to accommodate placement and rotation of a spool of wire thereon;height adjustable support members attached to the frame at the first end; andwherein the height adjustable support members are extendable to raise the first end of the frame above the conduit outlet to accommodate a wire pulling operation through the conduit outlet to a vertically downward descending conduit; andwherein the height adjustable support members are retractable to lower the first end of the frame below the conduit outlet to accommodate a wire pulling operation through the conduit outlet to a vertically upward ascending conduit;a wire collator outlet coupled to said frame in proximity to the first end, and wherein the height adjustable support members are extendable and retractable to raise and lower the wire collator outlet relative to the conduit outletwherein the wire collator outlet comprises a hoop rotatably coupled to the frame. 2. The wire cart of claim 1, wherein the height adjustable support members are extendable to raise the first end of the frame into horizontal proximity with the conduit outlet to accommodate a wire pulling operation through the conduit outlet to a horizontal conduit. 3. The wire cart of claim 1, wherein the height adjustable support members include casters on an end thereof. 4. The wire cart of claim 1, wherein the height adjustable support members include non-slip feet on an end thereof, further comprising a pair of wheels mounted on the frame. 5. The wire cart of claim 1, wherein the second end of the frame is adapted to support the wire cart thereon in a vertical orientation, and wherein the height adjustable support members are extendable to provide horizontal support and to maintain a horizontal distance from the conduit outlet during the wire pulling operation. 6. The wire cart of claim 1, wherein the height adjustable members are adapted to be reoriented from a height adjustable position to a horizontally adjustable position whereby the members are extended and retracted from the frame to position the first end horizontally further from and horizontally closer to the conduit outlet. 7. The wire cart of claim 1, further comprising horizontal positioning members adjustably mounted to the frame, and wherein the horizontal position members are extended and retracted from the frame to position the first end horizontally further from and horizontally closer to the conduit outlet. 8. The wire cart of claim 1, further comprising a plurality of pegs mounted on the frame and adapted to accommodate placement of extra spools of wire thereon. 9. The wire cart of claim 1, further comprising a plurality of pegs mounted on the frame on an upper surface thereof, the frame defining a plurality of receptacles in a lower surface thereof, the receptacles being configured to accommodate the pegs therein to facilitate stacking of wire carts. 10. The wire cart of claim 1, wherein the frame defines a male member at one of the first and second ends thereof and a female receptacle configured to accommodate the male member at the other of the first and the second ends to facilitate end-to-end assembly of wire carts. 11. A wire pulling apparatus, comprising:a frame;a plurality of spool support rods mounted in-line within a plane of a length of the frame;a pair of support members adjustably mounted transverse to the length of the frame at a first end thereof;a hoop rotatably mounted in proximity to the first end; andwherein the support members are adjustable to raise and lower a height of the hoop relative to a horizontal plane on which the wire pulling apparatus is placed. 12. The wire pulling apparatus of claim 11, further comprising a plurality of pegs mounted on the frame, the pegs adapted to accommodate storage of spools of wire thereon. 13. The wire pulling apparatus of claim 12, wherein the frame defines a plurality of receptacles therein adapted to receive the pegs to enable stacking of one wire pulling apparatus on another wire pulling apparatus. 14. The wire pulling apparatus of claim 11, wherein the frame defines a second end adapted to support the wire pulling apparatus in a vertical orientation relative to its length. 15. A method of facilitating a wire pulling operation through a conduit outlet mounted on a wall and attached conduit to wire a structure, the wire being initially stored on spools, comprising the steps of:providing a wire pulling apparatus, comprising a frame, a plurality of spool support rods mounted within a length of the frame to hold the spools of wire from which wire will be pulled, a pair of support members adjustably mounted transverse to the length of the frame at a first end thereof, and a hoop rotatably mounted in proximity to the first end;positioning the wire pulling apparatus in proximity to the conduit outlet;extending the support members to raise the hoop above the conduit outlet when the conduit outlet is coupled to a vertically downward descending conduit;retracting the support members to lower the hoop below the conduit outlet when the conduit outlet is coupled to a vertically upward ascending conduit. 16. The method of claim 15, further comprising the step of extending the support members to position the hoop into horizontal proximity with the conduit outlet when the conduit outlet is coupled to a horizontal conduit.
