June 3, 2013 – Highfield Manufacturing Company says it has developed a locking system featuring the industry’s first barrel lock without a keyway. The Paladin Lock and Key System also includes a “tool-like” key design with an ergonomic, rugged hand grip to help make installation and maintenance quick and comfortable. The Paladin Lock and Key System is designed to protect electric, gas and water utility meters with an added layer of protection against tampering and exposure to outdoor environments. The lock’s solid surface prevents picking or jamming with sharp objects and keeps debris, bugs, water and contaminants from entering the lock, it says.
