Double Expansion Anchors
🔩 Key Features of Double Expansion Anchors
Robust Construction
Double Expansion Anchors are built for durability and dependable performance across a range of environments.
Zinc-Plated Steel:
Offers a strong balance between mechanical strength and corrosion resistance. Best for general-purpose indoor or dry settings.
Stainless Steel:
Delivers superior corrosion resistance, ideal for outdoor, marine, or chemically aggressive environments.
Reliable Expansion Mechanism
The double expansion anchor features an internal taper system that drives uniform outward pressure.
As the tensioning bolt is tightened, the inner cone expands the shield, forcing it firmly against the masonry or concrete.
This ensures a mechanical interlock that provides strong holding power, even in weaker, hollow, or crumbly materials like cinder blocks or bricks.
Versatile Applications
Double expansion anchors are ideal for a wide range of medium to heavy-duty fixing needs:
Mounting Fixtures:
HVAC units, satellite dishes, handrails, heavy shelves.
Supporting Installations:
Pipe clamps, junction boxes, electrical panels, industrial equipment on masonry surfaces.
Outdoor and Structural Use:
Signboards, exterior lighting, safety barriers, or frames anchored into
