These 1/2" closed thread-on metal seals secure polypropylene strapping on bundled, palletized, or unitized loads. The closed-thread design requires strapping to be threaded through the seal before tensioning, producing a tamper-resistant closure that holds under the load stress typical of high-volume strapping operations.

The smooth interior bore grips textured polypropylene strapping without scoring or weakening it, making these seals well suited for warehousing, manufacturing, light industrial assembly, and freight distribution environments where consistent seal integrity is critical across long production runs.

Galvanized metal construction provides corrosion resistance for both indoor storage and transit conditions. Each seal measures 1.25" L x 0.50" W, sized for standard 1/2" polypropylene strapping. Cases contain 1,000 seals, a practical stocking quantity for facilities running continuous strapping lines or high daily shipment volumes. Cases ship via parcel carrier.
