Bill,
The ad was in Sept/Oct2002 IAEI News-"News Source"
"Cooper Wiring Devices Introduces New Mid-size Thermoplastic Wallplates"
...."designed to cover electrical installation gaps"
...."adds a full 0.375" (9.525mm) on all sides to NEMA standard-size plates, providing needed gap coverage for over cuts or other large wallboard-to-box openings"
(they also describe the product line as "exciting"...I guess somebody must lead a pretty boring life)...S
