A four-leaf expansion anchor with an open hook head, used for suspending rod, wire, chain or cable from concrete soffits and walls. The four-segment expansion sleeve spreads load more evenly across the hole wall than a two-leaf design, which matters in older or lower-grade concrete.
Supplied in bulk to distributors, importers and hardware brands worldwide, including private-label packaging in the customer's own branding. Non-standard sizes and made-to-drawing variants are produced to order, with a material test certificate on every consignment.
