Multifunction Caster Jack

We now build a caster jack especially for our multifunction unit. This jack fits between the end ladder frame and or outrigger and the caster. They allow adjustment for slightly greater overall height but are indispensible when working on uneven surfaces or even slightly uneven surfaces. How about using them on stair steps? Until now using a multifunction unit on stairs meant that the unit was never perfectly level unless you are very lucky and the step was exactly on the 2 in adjustment level. In our pics below you can see the unit was not exactly level when we took the photos. Now you put a set of these jacks in place and can get the unit dead level perfect. We invented these. Patent pending.
