A spooled wire dispenser cart (20) including a central frame (22) and a plurality of spaced spool bars (62). At the free end (66) of each spool bar (62) is a “spool retainer”(74). Each spool retainer (74) includes an elongate element (76) which has an “unblocking position”relative to the spool bar (62) wherein wire spools can be freely slid over the free end of the spool bar (62); and a “blocking position”relative to the spool bar (62) such that wire spools are prevented from sliding over the free end of the spool bar. A preferred wire cart (20) also includes a folding handle (46) which has an extended position useful for maneuvering the cart (20), and a folded position wherein handle (46) is compactly folded against the central frame (22) of cart (20).

A spooled wire dispenser, comprising: A. a central frame; B. a plurality of spaced, substantially horizontal spool bars supported by and extending outwardly from the central frame, each spool bar having a secured end connected to the frame and a free end opposite thereto; and C. spool retainer mans mounted on the free end of each spool bar for selectively allowing a wire spool to slide thereover, each spool retainer means having (1) a blocking mode wherein a wire spool cannot freely slide over the free end of the corresponding spool bar, and (2) an unblocking mode wherein a wire spool can freely slide over the free end of the corresponding spool bar, wherein the spool retainer means remains operatively connected to the free end of the spool bar in the blocking and unblocking modes of the spool retainer means; wherein: a. when each spool retainer means is in the blocking mode the spool retainer means extends substantially beyond the outer periphery of the corresponding spool bar, and when each spool retainer means is in the unblocking mode the spool retainer means does not extend substantially beyond the outer periphery of the corresponding spool bar; b. each spool retainer means comprises an elongate element which is substantially parallel to the corresponding spool bar when the spool retainer means is in the unblocking mode and is substantially perpendicular to the corresponding spool bar when the spool retainer means is in the blocking mode; c. the free end of each spool bar is tubular, having a thin peripheral wall and a hollow center, the peripheral wall forming a pair of notches which are parallel to one another and to the corresponding spool bar, the notches receiving the corresponding spool retainer elongate element when the elongate element is in the blocking mode, and the free end of each spool bar comprises a pin extending across and perpendicular to the notches; and d. each spool retainer elongate element forms an elongate slot having a first end located near the middle of the elongate element and a second end located near one end of the elongate element, and the elongate slot receives the pin extending across the notches in the free end of each spool bar, wherein when the elongate element is in the unblocking mode the end thereof forming the elongate slot is received by the hollow free end of the spool bar with the pin located at the first end of the elongate slot, and wherein when the elongate element is in the blocking mode the pin is also located at the first end of the elongate slot in the elongate element; wherein to convert the elongate element from the unblocking mode to the blocking mode the elongate element is (i) pulled axially out of the hollow end of the spool bar to the point where the pin is located at the second end of the elongate slot in the elongate element; (ii) rotated 90 degrees into a position perpendicular to the spool bar; and (iii) positioned such that the pin is once again located at the first end of the elongate slot in the elongate element, wherein the elongate element is held in the blocking mode by the notches and the pin, whereby the elongate element can assume the blocking mode without bearing against a wire spool and the wire spool can therefore spin freely on the spool bar when the corresponding elongate element is in the blocking mode.
