Allegion PLC (NYSE: ALLE), a leading global provider of security products and solutions, today announced the new LT Series of decorative tubular locks for use in high-end commercial and multifamily properties. Built from the same foundational technology of the popular Schlage L Series mortise locks, the LT Series tubular locks utilize the same lever designs as the L series and thus provide seamless suiting with both the Schlage mortise lock and most Von Duprin exit devices.
