  • The Marks USA Survivor Leverset has a Unique Clutch Mechanism that Radically Reduces the Wear and Abuse that Typical Cylindrical Lever Sets Endure
  • When Locked, the Levers of the Survivor Disengage from the Retractor and Other Interior Mechanisms of the Lock
  • The Levers of the Survivor Swing Freely, without Resistance
  • This Reduces the Amount of Wear on Lock Components and Eliminates Lever Droop
  • The Use of a Clutch Results in Longer Lasting, Lower Maintenance, Eloquent Solution
