Abstract
A system for securing at least two heating, ventilation, and air conditioning units stacked on each other for transportation includes corner brackets on at least the four corners of the lower unit and between the units. Each corner bracket has a banding channel, a plank-receiving channel, and a plurality of protrusions on a top side. The brackets are banded in place using the banding channels. On each longitudinal side, planks are used to extend between corner brackets to help control the loads and to distribute the loads. The corner brackets may be made from a synthetic material and the planks from wood or wood-like material. Other aspects are disclosed.
