Abstract
A pop-out T-handle assembly of the type containing a lock cylinder having high security features which defy forced entry is disclosed. A cylinder front handle and cylinder/extension housing are assembled around the cylinder lock and rigidly secured for protection against pulling the lock. The face of the cylinder lock is preferably protected by a freely rotating cylinder protector plate to protect against drilling into the cylinder lock. A locator tab and slot arrangement assures alignment of the cylinder lock bolt and a corresponding opening in the T-handle housing, as well as restricts lateral movement of the cylinder front handle within the T-handle housing to protect against prying. A T-handle clutch arrangement of a generally square configuration provides extensive bearing surface to absorb torque and prevent wear. An auxiliary locking mechanism for added protection against pulling the inner cylinder of the lock in the event that the cylinder protector plate is defeated or a method is devised to either pull or pry the cylinder front handle.
