Stud-Style Toggle Anchors for Hollow Block and Brick
 |
Create secure threaded-stud connections in hollow walls and ceilings, such as cinder blocks and hollow core panels. These anchors have the highest shear strength of any of our anchors for hollow block and brick, and are made in the U.S. Their toggle bar pivots inside hollow cavities for a firm hold. All are similar to toggle bolt anchors, but require a smaller hole, so you won’t end up with a gaping hole in your block or brick.
To install, position the washer on the anchor and thread on the nut. Then, push the anchor through your component into a drilled hole and twist the rod 180°—gravity drops the toggle into position. Tighten the nut to secure. You can remove your component by unfastening the nut. Twist the rod back 180° to collapse the toggle and remove the anchor.

Toggle Anchors for Hollow Block and Brick
 |
Embed in hollow walls and ceilings to create secure female-threaded connections that let you remove and reinstall a screw or threaded rod. These anchors have the highest pull-out strength of any of our anchors for hollow block and brick, and are made in the U.S. Often used in cinder blocks and hollow core panels, their toggle bar pivots inside hollow cavities for a firm hold. They’re similar to toggle bolt anchors, but require a smaller hole, so you won’t end up with a gaping hole in your block or brick.
To install, push the anchor through your component into a drilled hole and twist it 180°—gravity drops the toggle into position. Pull the anchor to secure. Twist the anchor back 180° to collapse the toggle and remove the anchor.

Anchors for Hollow Block and Brick
 |
Requiring minimal installation depth, these anchors are best for thin cinder block and hollow core panel walls and ceilings. All expand
when fastened to create permanent female-threaded connections that let you remove and reinstall a screw or threaded rod. They fit into smaller holes than toggle anchors for hollow block and brick but are not as strong.
To install, place the anchor into a drilled hole, cone end first. Tap the anchor into the hole until it's flush with the surface. Then, position your component, insert a screw or threaded rod, and tighten.

Mesh Anchors for Hollow Block and Brick
 |
 |
Create a secure connection that withstands vibration better than any of our other anchors for block and brick. The mesh on these anchors grips adhesive (sold separately), preventing it from running into the cavities of hollow block and brick to secure threaded rods or screws. To achieve the stated strengths, you must use the adhesive listed. A good option for outdoor use, these anchors are made of 18-8 stainless steel to resist rusting while your adhesive seals out moisture.
To install, first fill the mesh anchor with adhesive and press it into a drilled hole. Then, press the tab against your block to hold the anchor in place, and insert a threaded rod or screw. The rod or screw will push the adhesive out of the mesh, forming a plug that keeps the rod or screw in place once the adhesive dries. Once installed, the rod or screw can’t be removed.
