Extended one piece bearing sleeve offers added support for interlocking stainless steel tubes and provides for extra lever rigidity. Requires standard 2-1/8” (53.97mm) bore through door.

  • OverDrive™- Freewheeling lever action occurs when latch retraction mechanism disengages from lever handle when lever is locked. Built-in stops in the rose insert prevent lever from traveling beyond approximately 57 degrees. Additional 40% spring power in rose insert on OverDrive™ side of door ensures that lever handle return to the horizontal position.
