LP-TK-03 thumb knob is a CompX Timberline lock component designed specifically for use with all CompX Timberline cylinder bodies, so it drops into the same interface as the keyed plug and keeps the lock body useable in multiple situations. Because this thumb knob works as a general thumb latch when keyed lock plugs are not required, it lets you operate the cylinder manually where key control is unnecessary. The part can serve as a shipping plug, so a cylinder body stays protected and functional during handling. It also functions as an insert for testing locks during manufacturing, giving production teams a repeatable way to cycle and check Timberline cylinder bodies without cutting or tracking keys.
This CompX Timberline thumb knob is specified for use with all CompX Timberline cylinder bodies, so it shares the same interface those bodies expect from a keyed plug during assembly. Because it works as a general thumb latch when keyed lock plugs are not required, installation into the cylinder body keeps the mechanism active without adding key management steps. When the LP-TK-03 is used as a shipping plug, it sits where the keyed plug would, helping the body arrive at the next stage ready for either testing or final plug selection. The ability to act as an insert for testing locks during manufacturing ties the same fitted position to repetitive cycling, which supports consistent assembly flow.
The LP-TK-03 thumb knob is for use with all CompX Timberline cylinder bodies, so it fits any Timberline body position that would normally accept a keyed lock plug. In cabinet or fixture builds that rely on CompX Timberline lock bodies, the part works as a general thumb latch when keyed lock plugs are not required, turning the cylinder into a hand-operated latch point. In production or staging, the same LP-TK-03 can serve as a shipping plug, sitting in the cylinder opening while the casework or hardware assemblies move between workstations. During manufacturing of Timberline-based locks, it is used as an insert for testing locks, so bodies can be assembled, cycled, and evaluated before any final keyed plug is chosen.
Because the LP-TK-03 is designed for use with all CompX Timberline cylinder bodies, installers and manufacturing teams rely on one thumb knob pattern to match every Timberline body they deploy, which streamlines part pulls and reduces changeovers during lock work. When it functions as a general thumb latch, the knob converts the cylinder body into a simple manual latch point, so projects that do not call for keyed plugs still use the same Timberline hardware footprint. As a shipping plug, the LP-TK-03 fills the cylinder opening with a working turning member, which lets teams handle assemblies while the lock body remains ready for later testing or keyed plug selection. Used as an insert for testing locks during manufacturing, it gives a consistent way to rotate Timberline cylinder bodies on the line, supporting repeatable function checks and efficient pass/fail decisions.
The LP-TK-03 thumb knob is for use with all CompX Timberline cylinder bodies, so it fits any Timberline body position that would normally accept a keyed lock plug.
The LP-TK-03 works as a general thumb latch when keyed lock plugs are not required, so the lock body can be turned by hand instead of using a key.
The LP-TK-03 can be used as a shipping plug in CompX Timberline cylinder bodies, so the cylinder opening stays occupied and functional while assemblies move between stages.
The LP-TK-03 is an insert for testing locks during manufacturing, giving production teams a repeatable way to cycle CompX Timberline cylinder bodies without cutting keys.
The LP-TK-03 works as a general thumb latch when keyed lock plugs are not required, so projects that need a simple latch can still use Timberline cylinder bodies.
The LP-TK-03 thumb knob carries manufacturer part number LP-TK-03, which ties directly to CompX Timberline documentation and ordering systems.
The LP-TK-03 thumb knob from CompX Timberline Lock is built for use with all CompX Timberline cylinder bodies, so one part number covers latch, shipping plug, and testing needs across Timberline-based work. Because it works as a general thumb latch when keyed lock plugs are not required, it lets you apply Timberline bodies even on non-keyed jobs while keeping operation straightforward. Its ability to act as both a shipping plug and an insert for testing locks during manufacturing gives shop and production teams a single, repeatable way to protect and cycle Timberline cylinder bodies. Select the LP-TK-03 when a CompX Timberline thumb knob that supports latch function, staging, and manufacturing test roles under one part number fits the job plan.
