This item was created to hold an enclosure box on a 4" diameter rod in order to combine 6 different sets of wires into one. Two of these clamps were printed and screwed into the flange on the top and bottom of the box. Then screws were used to clamp down the two separate parts of the clamp around the rod in the desired position. Somthing similar would be an enclosure pole mounting kit. A competitor's kit can be found here: http://www.l-com.com/nema-enclosures-enclosure-pole-mounting-kit-pole-diameters-4-to-7-inches for $62.37. It costs $1.56 to print both of these clamps in 2 hours and 40 minutes using 78 grams of PLA.
