(b) at least one hinge boss on each of the pair of side cable guides, the at least one hinge boss being disposed at the end of one of the generally T-shaped projections;

(c) a door, having a center panel and a hinge structure along edges thereof to receive one or more of the hinge bosses, thereby facilitating rotatable attachment of the door to the side cable guides; and

(d) a seperate midsection member for interconnecting the pair of side cable guides, wherein the midsection member is adapted to be received in sockets arranged in the pair of side cable guides;

(e) wherein the door is adapted to be opened along either side thereof by detaching the hinge structure from the at least one hinge boss at one side of the door and rotating the door about another at least one hinge boss at the opposite side of the door; and

(f) wherein the hinge structure includes a stop adapted to bear against the at least one hinge boss, thereby preventing the door from becoming misaligned with the pair of side cable guides.

2. The cable manager of claim 1 , wherein each socket has a large taper such that the width of an entrance thereof is wider than the width of the midsection member and the interior of the socket is narrower than the entrance.

3. The cable manager of claim 1 , wherein the midsection member includes a web having flanges at opposite sides thereof.

5. The cable manager of claim 1 , wherein the web includes at least one alignment slot at an end thereof and extending inwardly, the alignment slot being adapted to fit over a shelf in each socket.

6. The cable manager of claim 1 , wherein the web includes at least one alignment boss disposed at or near an end thereof for positioning the midsection member laterally within each socket.

7. The cable manager of claim 1 , wherein the web includes at least one locking aperture disposed at or near an end thereof for engagement with a locking tab within each socket, thereby retaining the midsection member therein.

8. The cable manager of claim 7 , wherein the locking tab is beveled to permit the midsection member to be snap fit.
