The Powers Wall-Dog is the industrys first all steel one-piece screw anchor, which features high-profile threads for easy fastening into wallboard and other masonry base materials. Its deep cutting, corkscrew-like threads provide for smooth entry and a powerful hold, and when removed the Wall-Dog leaves a much smaller hole than toggles or other systems. For aesthetic appearances, the Wall-Dog is available in five color finishes: White, Chrome, Black, Brass and Bronze. It is also available in five head styles: Hex, Wafer, Robertson, Oval and Pan. For fastening into wallboard or wood, no pre-drilling is required. The anchor is inserted through the fixture and screwed in with an ordinary Phillips screwdriver or screw gun. Fastening into concrete, hollow or grout-filled block, brick and plaster requires a pre-drilled 3/16 ANSI hole. Powers Wall-Dog anchors are ideal for light to medium duty anchoring. Typical applications include lightweight fixtures, drapery supports as well as electrical, telephone and cable accessories.Stanley Black and Decker (Powers Fastener)
