To help keep supplies handy, David Bryant with Smoky Mountain Cattle Consultants near Cleveland, Tenn., installed a lockbox on the side of his portable chute. The box was purchased through a farm-supply store, and he customized it by putting his business logo on the front. To mount the box, he welded heavy-duty L-brackets to the chute, then placed pieces of rubber machine belting between the box and the brackets to provide a cushion and hold the box securely in place.
