Plano Foot :
This part is critical to positioning of the outside upright. It supports the upright during loading of your PLANO so that it sits just slightly below the inside upright as you load. The extension of the foot is designed to slip inside the bottom of the inside upright, thereby keeping the uprights aligned with one another to ensure that loading of your PLANO is simple and easy. Remember - the foot must be installed in the outside upright (NOT the one against the wall).
