The industrial edger comprises an elongated tube having an exterior surface over which the rope passes, a slot cut along the length of the elongated tube to allow placement of the industrial edger over the edge, and end plates attached to both ends of the elongated tube to prevent the rope from sliding off of the elongated tube. Dividing plates may be attached to the exterior surface of the elongated tube to provide multiple channels for the use of multiple ropes protected by one industrial edger. A roller may be placed on the top of each end plate to reduce friction from an object, e.g., a backboard, sliding over the industrial edger. A retaining rod may be removably mounted parallel to the elongated tube, attached at the end plates, to prevent a loose rope from coming off of the industrial edger. A mobilizing roller may be placed on each end plate within the slot to facilitate easy movement of the industrial edger along the edge. ## Claims ### Claim 1 An industrial edger for protecting a rope passing over a sharp edge, comprising: an elongated tube having a first open end, a second open end, an exterior surface, and a tube slot cut along a longitudinal axis of said elongated tube from said first open end of said elongated tube to said second open end of said elongated tube, said tube slot defining a longitudinal opening and having an interior surface;
