Our 1/2" Open Metal Seals are great for sealing steel strapping. The 1/2 inch metal seal keeps the strapping in place and secure. The slip resistant snap on strapping seal prevents loosening and provides a durable hold for transporting when suppressed and notched with the strapping sealer. This seal is most effective when applied with our strapping sealer and strapping tensioner. Theses open metal seals come 1000 per case.
