Abstract
Several embodiments of an end cap are provided for use with a spreader bar system for distributing the lift force of a load across multiple points. The end cap comprises at least one lifting lug with the shackles positioned therethrough, along with at least one visual indicium for keeping a minimum of a 45 degree lift angle. Additionally, the end cap is provided with a pinch bolt system for easy assembly as well as a flat, horizontal foot plate located beneath the end cap for quick alignment. A four-point embodiment duplicates these features and positions two end caps at a 90 degree perpendicular angle atop a support plate. Additionally, a method of use is provided for pre-calculating maximum load so as to reduce the computation to a single chart.
