142403-3 supersedes older part numbers: 140739-4

Makita 142403-3 — Trimmer Base Complete (Trimming/Router Base). This is the original Makita replacement base assembly for the compact RT07-series routers: a finished trimmer/base plate that secures to the router body and provides a stable, flat surface for edge‑trimming and template work.

Fits example models such as RT0700C, RT0701C and several CX/kit variants (RT0700CX3, RT0701CX3, RT0701CX7) and matches other regional model codes sold under XTR/DRT prefixes; it also replaces Makita part 140739-4. (Model compatibility listings vary by region — confirm your model label before ordering.)

Why choose this part: it’s a genuine Makita trimmer/base assembly manufactured to the same fit and mounting points as the factory unit, so it lines up with the RT07 series’ base mounting and quick‑release features for easy removal and reinstallation. Ideal if you’re repairing a worn, cracked or missing base — an exact replacement among power tool parts that restores correct tool geometry and edge control.
