Female-Threaded Toggle Anchors for Hollow Block and Brick
A pivoting toggle bar creates a strong hold. These anchors provide an internally threaded socket connection for threaded rods and bolts. To install, push through a drilled hole; gravity drops the toggle into position. Anchors are removable and reusable. Made from zinc yellow-chromate plated steel, they resist corrosion in wet environments. Pull-out strength values are 25% of the ultimate values.

Adhesive Anchor Screen Tubes for Hollow Block and Brick
Used with adhesive in bricks and hollow blocks, such as cinder blocks, these mesh tubes create a stronger hold for rods and studs than other anchors. To install, first fill tubes with adhesive (sold separately) and press them into a drilled hole. Hold tubes in place by pressing the tab against your block, and insert a rod into them. The rod will push the adhesive out of the mesh screen, forming a plug that keeps the rod in place once the adhesive dries.
