As shown in the picture below we added a lower access door. The opening was trimmed with scamp fiberglass edge trim. By calling Scamp we discovered this product is is something they have made for them. (Cost is $2.50 per 4ft stick....plus shipping, OUCH!....so try to bundle with other order needs.)
We decided to go with the adjustable track type shelf supports with wire rack shelves.
Four support tracks, 3ft long each were mounted vertically on the side walls of the closet; two toward the front and two to the rear of the closet. We used three machine screws from the out side with nylon core locking nuts inside on each track. Be sure to take the position of the shelf cross wires into account when positioning the the vertical tracks
