Safe lifting, handling and transportation of precast concrete elements rely heavily on properly embedded transport anchors. When anchors are set into formwork, open cavities remain on the concrete surface after casting. Without proper protection, these openings can fill with concrete slurry, dust or moisture, which creates extra cleaning labour and may interfere with lifting connector engagement at the factory or construction site. Matching plastic plugs serve as a simple, functional accessory to maintain usable hole conditions throughout precast production workflows.

The double‑head transport anchor is a steel insert with two formed heads along its shank. Fabricated from hot‑dip galvanized steel, it is positioned and secured inside formwork prior to concrete pouring. Its matching plastic plug is moulded from high‑strength engineering plastic, delivering good impact resistance and corrosion resistance. During formwork preparation, the anchor is fixed in place; the plastic plug is then fitted over the exposed opening, sitting flush against the formwork face. Multiple plug sizes are available to correspond to different anchor dimensions.

Installed plastic plugs create a physical seal over the exposed cavity of the double‑head transport anchor. They keep concrete slurry, dust and moisture out during pouring, curing, stockpiling and component transit. This prevents hardened concrete deposits from forming inside lifting holes. Plugs can be removed after demoulding; many units can be cleaned and reused across multiple production batches. By keeping cavities intact and free of debris, the plugs also help preserve clean surface finishes on finished precast units.

This anchor‑and‑plug combination sees regular use across a broad scope of precast work. Application areas include precast wall panels, concrete beams, columns, slabs, bridge components, industrial buildings and general infrastructure projects. Well‑protected lifting holes reduce hole‑cleaning work before lifting operations. This supports consistent cycle times for precast fabricators and helps general contractors maintain predictable progress during on‑site erection.
