K-Wick Cable Hangers
IF USING "K-WICK" CABLE HANGERS– then refer to illustration below. Figure A represents the forming of a loop around a beam or other object from which the duct will be suspended. Figure B and C illustrate the way the cable goes through the free sliding end of the ‘clutcher’, around the duct and back through the hole in the ‘clutcher’ that contains the gripping bar. A ‘thumb tab’ (D) on the side allows for release of the cable if needed.

| Working load it duct only. Break load is upper limit capacity. To determine size and/or number us weight of duct if it is plugged with material. Ex: An 8" duct has volume of .34 cubic ft per foot. (A=(3.14(pie)x 16 (r2) x 12")/1728 (cubic inches per cube). If your material weighs 15 lbs/cu ft, then an 8" duct will weigh the amount of the metal plus 5.1 lbs. per foot. |

| NOTE: When hanging duct, it is suggested that you hang the duct at opposing 30-45 deg angles so as to prevent the duct from swinging. |
