The Toggle Strap Hollow Wall Anchor is designed for use in hollow base materials up to 64mm thick. The Toggle Strap is a pre-assembled anchor consisting of a carbon steel wing and a locking cap assembly moulded from engineered plastic. The Toggle Strap Hollow Wall Anchor works by inserting the wings horizontally into the drilled hole, pulling firmly on the strap to set the wings against the cavity, and sliding the cap forward until the flange is seated flush against the work surface. The plastic strap is then snapped off, leaving an M6 internal thread available within the cavity to anchor to.
