The wire or cable is pulled through a cable fitting by installing a roller support structure containing rollers onto the fitting. In some embodiments the rollers are removed from the cable fitting after a cable is pulled through the fitting. For efficient roller removal, the roller support structure has positioning and holding plate pairs. By moving the positioning plates relative to the holding plates, the rollers are held in place or dropped from channels in the holding plates. In another novel embodiment, a cable fitting slide plate structure is used to move a cable through a cable fitting. This structure includes a low friction inside bottom surface plane of arcuate shape for efficient movement of the cable through the fitting. ## Claims ### Claim 1 A method comprising: mounting a roller support structure on a cable fitting, wherein the roller support structure has a first positioning and holding plate pair and a second positioning and holding plate pair and a roller, on a cable fitting, and wherein the cable fitting has a first opening and a second opening; and moving a cable through the first opening into the cable fitting, over the roller of the roller support structure, and out of the cable fitting through the second opening. ### Claim 2 (depends on 1) The method of claim 1, wherein the first positioning and holding plate pair and the second positioning and holding plate pair of the roller support structure each comprises a positioning plate and a holding plate. ### Claim 3 (depends on 2) The method of claim 2, wherein said mounting involves moving the positioning plates of the first and second positioning and holding plate pairs relative to the holding plates of the first and second positioning and holding plate pairs. ### Claim 4 (depends on 3) The method of claim 3, wherein said moving of the positioning plates of the first and second positioning and holding plate pairs involves sliding of the positioning plates of the first and second positioning and holding plate pairs relative to the holding plates of the first and second positioning and holding plate pairs. ### Claim 5 (depends on 1) The method of claim 1, wherein said moving of the cable involves sliding the cable through the cable fitting. ### Claim 6 (depends on 1) The method of claim 1, wherein the cable fitting defines an interior volume, the roller being disposed in the volume. ### Claim 7 (depends on 2) The method of claim 2, further comprising: detaching the roller from the roller support structure after said moving of the positioning plates of the first and second positioning and holding plate pairs, the roller being detached when the cable is disposed in the cable fitting. ### Claim 8 (depends on 1) The method of claim 1, wherein the roller support structure comprises a plurality of rollers. ### Claim 9 (depends on 2) The method of claim 2, wherein the roller support structure comprises a movable handle and wherein the moveable handle is connected to each of the positioning plates of the first and second positioning and holding plate pairs, the method further comprising: moving the handle and the positioning plates of the first and second positioning and holding plate pairs relative to the holding plates of the first and second positioning and holding plate pairs. ### Claim 10 (depends on 1) The method of claim 1, wherein the first opening has a cross sectional area of at least three inches. ### Claim 11 (depends on 2) The method of claim 2, wherein the cable is simultaneously moved through a second cable fitting, and wherein a second roller support structure is mounted on said second cable fitting. ### Claim 12 (depends on 2) The method of claim 2, wherein said cable has a diameter of at least two hundred square millimeters. ### Claim 13 (depends on 2) The method of claim 2, further comprising: unmounting the roller support structure from the cable fitting after said moving. ### Claim 14 (depends on 2) The method of claim 2, wherein the interior volume of the cable fitting is defined by an inside bottom surface, the inside bottom surface being disposed in an inside bottom surface plane, wherein the cable fitting has a cover plate mating surface being disposed in a cover plate plane, the roller is disposed between said inside bottom surface plane and said cover plate plane, wherein the roller is disposed between the cable and the inside bottom surface plane during said moving of the cable through the cable fitting. ### Claim 15 (depends on 14) The method of claim 14, wherein there is a second roller disposed between said inside bottom surface plane and said cover plate plane, wherein the rollers are disposed between the cable and the inside bottom surface plane during said moving of the cable through the cable fitting. ### Claim 16 A device comprising: a roller; and means for moving the roller after pulling a cable through a first opening in a cable fitting over the roller and out of the cable fitting through a second opening of the cable fitting, wherein the means has a first positioning and holding plate pair and a second positioning and holding plate pair. ### Claim 17 A roller support structure comprising: a frame having a rectangular edge, the edge having a width; a first positioning and holding plate pair that extends from the frame, wherein the first positioning and holding plate pair has a positioning plate and a holding plate; a second positioning and holding plate pair that extends from the frame, wherein the second positioning and holding plate pair has a positioning plate and a holding plate; and a roller that is supported by the holding plate of the first positioning and holding plate pair and by the holding plate of the second positioning and holding plate pair. ### Claim 18 (depends on 17) The roller support structure of claim 17, wherein the frame has a length, the length of the frame being greater than the width of the rectangular edge of the frame. ### Claim 19 (depends on 17) The roller support structure of claim 17, wherein the roller support structure includes a plurality of rollers that is supported by the holding plate of the first positioning and holding plate pair and the holding plate of the second positioning and holding plate pair. ### Claim 20 (depends on 19) The roller support structure of claim 19, wherein the rollers of the plurality of rollers have axes and the intersections of the axes of the plurality of rollers and the holding plate of the first positioning and holding plate pair scribe an arc, and wherein the arc is less than a half circle.
