Sargent 09-0019 Knob Retainer | For 8 Line Bored Locks

The Sargent 09-0019 is a genuine OEM replacement knob retainer specifically engineered for the Sargent 8 Line Series of Grade 1 bored-in locks. Identified as Part #6 in technical parts diagrams, this retainer is the mechanical "anchor" that holds the knob assembly securely onto the lock chassis. Because the 8 Line series is renowned for its "T-Zone" construction and unequaled durability in high-traffic applications, using factory-correct retainers is vital to prevent knob wobbling or complete handle failure.

Institutional Grade Features & Benefits

• Direct 8 Line Compatibility: Precision-engineered for the unique internal interlocking architecture of Sargent's legacy 8 line knob sets.
• Essential Security Component: Two retainers are required for every 8 line lock (one for each knob) to ensure the handles remain permanently fixed to the spindle.
• Discontinued Part Support: As the 8 line series has been discontinued by the manufacturer, these genuine parts are essential for maintaining existing high-security installations.
• Convenient Multi-Pack: Sold in packages of 5, providing enough hardware to fully service two complete locksets with a spare for your maintenance kit.
• Restores Mechanical Stability: Replacing a bent or worn 09-0019 retainer eliminates "handle play" and ensures the knob retracts the latch with factory-spec precision.
