Product Details

Everything you need to know — features, specs, fitment, and answers to the most common questions.

Petal design clamps behind the wall

Expanding petals flare out and lock behind the material — mechanical hold, not just friction, so soft or hollow walls stop spitting anchors.

Holds in block, brick, and hollow material

Spreads the load across the petals for a secure bite where standard sleeve anchors spin or pull out.

Torque down with confidence

Once set, the bolt draws tight without the anchor rotating in the hole.

Lifetime warranty included

No receipt needed for replacement. Orders ship same-day from Columbus, OH.

Do these work in hollow block or only solid material?
Both — the petal expansion clamps behind hollow block webs and also grips in solid material. Drill the hole to the specified diameter; an oversize hole is the number one cause of anchor spin.
Warranty policy?
Lifetime warranty. If they fail under normal use we replace them — no receipt, no questions.
When do orders go out?
Same day from Columbus, OH if ordered before 2pm ET. Free standard shipping on $49+ orders.

Finally an anchor that holds in crumbly block
Old strip mall walls with soft, crumbly block eat regular anchors. The petal expansion design spreads the load and these held a run of heavy shelf standards that plastic anchors kept spitting out. Torqued them down and nothing moved.

Hung a lit channel sign in old brick
Used these to mount a sign cabinet on 1950s brick. The petals flare behind the material and clamp instead of relying on friction alone. Pull-tested one before committing — held way past what the sign weighs.

Solid hold, drill the right size hole
Mounted a TV bracket into block wall in the basement. First hole I drilled slightly oversize and the anchor spun — drilled the correct diameter and the second one locked up rock solid. Follow the sizing and these are excellent.
