Hi TheBerrys. Checked on the receptacle manufacturer today. It had two web sites I checked them & it turns out that; Rubbermaid appears to be the parent company of Rolodex. I was able to locate product photos at: Rolodex
go to "Virtual" workspace, skip the intro, then go to Hub systems. Product photos are located there. I did not check but they may list a location where they are sold.
The price at the location where I find them is $ 3.00 each. Good Luck & I hope that this information helps.
