These plastic conical anchors are intended for light duty anchoring applications and offer extra support for loads. Once installed, they provide a flush, clean appearance in drywall. The anchor's fins prevent the anchor from turning in the hole during and after installation. The split in the anchor ensures three-way expansion on sides for increased holding power. Used with sheet metal, wood and lag screws in hollow walls. Can be used in light masonry or masonry block applications. Requires a pre-drilled hole for installation.
