Cable guide with automatic cable release

A cabling device comprising:

• a rigid frame having an upper frame member, a first lateral frame member extending from a first side of the upper frame member, a second lateral frame member extending from a second side of the upper frame section opposite the first side of the upper frame member, a first lower frame member extending from the first lateral frame, and a second lower frame member extending from the second lateral frame member, the first and second lower frame members extending towards each other, whereby the upper frame member, the first and second lateral frame members, and the first and second lower frame members define a mostly bounded interior;
• a plurality of rollers supported within the mostly bounded interior of the rigid frame, the plurality of rollers defined by an upper roller supported by and between the first and second lateral frame members adjacent the upper frame member, a first lateral roller supported by and between the upper frame member and the first lower frame member, a second lateral roller supported by and between the upper frame member and the second lower frame member, and a lower roller pivotally connected to the first lateral frame member and extending between the first and second lower frame members, the lower roller pivotable so as to define a closed position wherein the mostly bounded interior is closed, and an open position wherein the mostly bounded interior is open;
• and
• an actuation system connected to the pivotally connected lower roller and operable to automatically control pivoting of the pivotally connected lower roller.
