Makita 450950-3 Spare Part - LOCK LEVER RP1801

Makita 450950-3 — Lock lever (original Makita)

A direct-fit lock lever for Makita plunge routers — part number 450950-3 — designed to restore the plunge-lock action on affected Makita router bases. It is the lever that engages/releases the plunge lock and mounts in the plunge assembly; the parts diagram shows it installed alongside a pan-head M5×12 screw, a compression spring (listed as “compression spring 13”) and a 7.1 mm steel ball in the same assembly.

Fits (examples): RP1800 / RP1800F, RP1801, RP1803 and several RP2300‑series plunge routers such as RP2301FC, RP2302FC and RP2303FC (these models use the same lock‑lever part number in the Makita parts diagrams).

Why this part matters: if your router’s plunge won’t lock solidly or the lever is cracked/worn, replacing it with the original Makita lock lever returns the same fit and function so adjustments hold reliably. The lever is engineered to mate with the existing M5 fastener, spring and locating ball in the base assembly, so installation is a straightforward swap with basic hand tools.

What you’ll get: one genuine Makita lock lever (450950-3), ready to install into the plunge assembly for the listed RP models.

(If your model isn’t listed above, check the parts diagram for your exact model to confirm the 450950-3 part number is shown in the plunge/base assembly.)
