ARMLOK rings also meet United Parcel Service and United States Postal Service requirements. listene. Specul The HDPE plastic ARMLOK ring carries a U.S. Patent and is recyclable. Tasted and cerified to meet and exceed 95-100 kPa hydroscopic pressure tests, ARMLOK is used by manufacturers to safely transport hazardous materlals vla air, sea and parcel service. ARMLOK rings also serve as a tamper-evident device. Appis In ARMLOK rings are quick and easy to apply. They reduce the potential for workers' comp claims posed by all metal alternatives. ARMLOK can be applied by hand, rubber mallet, Harbll press, or a roller device. High speed application methods are being developed and your Brockway Standard Technical Support Group can assist in set-up. *Sizes are inches (1st digit), and sixteenths of an inch (2nd and 3rd digits).
