Information needed about DAK SPC-3000

Hi, folks. I can't seem to find any information about a "spike protector" produced by DAK Industries called the SPC-3000. A client submitted only this product name and a photograph of a boxy unit similar to amp or tuner in shape. The skeletal DAK site has nothing, and even Google search results turn up nothing. I'd love a product description, original retail price, something! Thanks very much.
