Summary:
Why Quality Control in Handcuff Manufacturing Is Critical to Law Enforcement Safety
🔍 Manufacturing for Safety Starts with Quality
At KELIN, every pair of handcuffs we produce is subject to a strict quality assurance process, designed to protect the end users—law enforcement officers.
We understand that one defective restraint in the field could mean an operational failure or officer injury. That’s why we make QC a core part of production, not an afterthought.
