Lok Links were born due to a real world problem. Fixing and attaching chains for safety and security require a permanent solution. Typical quick links and carabiners can be released and removed. Until now, the only way to permanently attach a chain or securely lock an asset was to weld it. However, welding requires equipment, time and often hot work permits. Lok Links need none of these. Simply loop through, attach and close the link. Closing the link shoots a spring loaded pin into the link body preventing it from being reopened. Simple. Safe. Secure. Strong.
