The 83/80 is a professional rekeyable padlock for highest security requirements. This lock accepts most restricted keying systems. It is used to secure gates, sheds, containers, etc. The body and shackle are made of hardened steel with NANO PROTECT™ coating for extra corrosion resistance. The patented "Z-bar" allows the padlock to be converted from non-key-retaining to key-retaining and vice versa within seconds. A special cover is available upon request to protect the cylinder against moisture and dirt.
