EXPANDS BEHIND THE PANEL

A Petal-Shaped Anchor That Grips from the Back

During installation, the slotted metal body compresses and expands behind a compatible panel. This creates a wider rear contact area while the front flange remains seated against the surface.

⚠️ Installation & Load Notes

Confirm the anchor size, hole diameter, grip range and panel thickness before drilling.
Use a compatible setting tool and do not overtighten, which may damage the panel or threads.
Load capacity depends on substrate material, thickness, edge distance, installation quality and fastener size.
Zinc plating improves corrosion resistance but does not make the fastener completely rustproof.
Do not use for overhead, structural, fall-protection or other safety-critical loads without engineering approval.
