Rugged and Torque Resistant

Direct linkage with fixed alignment between the hub and the latch bolt is the best construction for quietly and effectively operating the latch. For this reason, SARGENT has 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 the 8 line knob lock outstanding!
