Sure Wall anchors are designed to self-drill into drywall and provide excellent holding value and greater capacity than screws alone. The standard Sure Wall cuts threads into drywall, greatly increasing the bearing surface and strength of the fastening. The Sure Wall Gripper expands behind the drywall, greatly increasing the bearing surface, resulting in higher loads than the standard Sure Wall. The Sure Wall Nylon Toggle has a die-cast, zinc-drilling point that toggles into position to provide the most bearing surface behind the drywall and the highest capacity in the Sure Wall product line.
