T-Zone Construction
Direct linkage with fixed alignment between the hub and the latchbolt is the best construction for quietly and effectively operating the latchbolt. For this reason, SARGENT developed the interlocking aligning and latch tubes, which form a rugged torque resistant “T” in the critical twist area. This “T-Zone” construction, combined with long lasting components, makes 11 Line bored lock outstanding!
