Design Features & Key Benefits

• Three-Piece Expansion Sleeve: As the hexagon bolt is torqued, the heavy-duty metal sleeve expands uniformly along the borehole walls, distributing the load precisely across the concrete matrix.

• Integrated Collapsible Plastic Ring: Features a specialized plastic compression section on the sleeve. This element deforms during tightening to pull the fixture tight against the base material, eliminating any air gaps or shifting.

• Certified Reliability: Holds a European Technical Assessment (ETA Option 7) approval for non-cracked concrete, validating its usage for high-security structural connections.

Application:

Specified for commercial mechanical anchoring, structural steel attachments, and industrial installations into solid concrete or hard natural stone. Ideal for securing structural columns, heavy storage racks, base plates, industrial machinery, ventilation brackets, and protective steel guardrails.
