Nylon toggle anchors are designed for hollow wall applications in wallboard and panelling. This toggle is designed to flare out creating a tight triangular clamp behind the hollow based material. The screw penetrates into the anchor making the tabs flare out creating a triangular shape. The extruded points that align the wings ensure extra grip to the material. Drill a 5/16" hole. Squeeze toggle together and push into the hole until flush with wall. Position fixture over the anchor. Insert the screw and tighten until it feels secure.
