In past issues of EC&M magazine I noted an ad for a clear disposable plastic cover that can be installed over outlet and switch boxes during the rough-in prior to the plaster making a mess of the box.  Anyone know the name / source of such a product?  I am having trouble finding these and could use them for a large project I am on.
