Abstract: Efficiently reduces plastic non-pressure rated water bottles to less than ¼ of their original inflated size. By means of rolling one up with a hand held tool to create recycle space. In addition the Enviropactor Wrench will also insert up to 10 plus Toilet Tissue/Paper Towel Tubes one inside the other in turn dramatically increasing your cardboard recycle area. It will make a huge difference in the recycle of plastic water bottles and household cardboards. I can put 60 inflated water bottles in a 13 gallon trash bag and if I use the Enviro-Pactor Plastic Water Bottle Wrench then I can put 420 plastic water bottles in the same size trash bag. Can be used indoors and outdoors under any human conditions. Can be used anywhere bottled water is used or drank. The more we use it the more we will benefit from it. The Enviro-Pactor Plastic Water Bottle Wrench is simple original, simple to use, environmentally friendly, fun.

Abstract: A method of tensioning park cables of a park brake system includes positioning a tension indicating device between an adjuster and an adjusting nut when the park brake system is disposed in a slack position. The tension indicating device includes an axial spacing length between the adjuster and the adjusting nut that is equal to a desired adjustment distance of the park cables when the park brake system is disposed in the slack position. The adjusting nut is then tightened until the tension indicating device indicates that the park cables include a tension equal to a target tension level of the park cables when the park brake system is disposed in an applied position. The tension indicating device is then removed from between the adjuster and the adjusting nut, thereby introducing slack into the park cables that is equal to the axial length of the tension indicating device.
