ABSTRACT:
A portable leveling device capable of supporting any types of ladders, scaffolds, and other objects requiring leveled support regardless of object size when a plurality of the devices is used. The device may be deployed by one hand automatically and instantly quick over a terrain of virtually any profile. The device is capable of projecting an extension ladder position eliminating human error and reducing deployment time when the ladder is actually positioned. The device is capable of indicating deployment faults before use and allows visual inspection of the parts at fault without disassembling. The device is lightweight, can be easily carried with one hand, and stored compactly.
