The Makita 193155-9 2-1/2" Clear Sub Base is a router base accessory made for select Makita 2-1/4 horsepower routers. This is a router sub base designed for improving visibility and bit clearance during edge routing, inlay work, and dado cutting. Model number 193155-9. If you run a Makita fixed-base router and want a clearer view of the workpiece than a standard dark base gives you, this is the part that solves that problem.

What makes this piece useful is not just that it replaces the factory base, but that it changes how easy it is to follow a line and keep the cut where you want it. The clear plastic construction lets more of the work surface stay visible while you route, which is especially helpful when you're working close to layout lines, trimming an edge, or setting an inlay where placement matters. The 2-1/2 inch center hole also gives you more room for larger router bits than a tighter opening would.

Makita built this sub base from transparent plastic rather than the standard black style that can block your view. That sounds simple, but on real work it makes a difference. When you can see more of the bit area and more of the material under the base, it is easier to stay accurate and easier to work confidently around corners, edges, and pattern details. For fine woodworking, trim work, and detail routing, that added visibility is the real value here.

This accessory is also a straightforward upgrade instead of a complicated add-on. Makita states that it installs quickly and easily, so it is a practical replacement part for users who want to improve visibility without changing routers or adding a specialty base assembly. For pros already running a compatible Makita router, it is the kind of small part that can make the tool easier to use day after day.

Compatibility matters with router accessories, and this sub base is designed specifically for Makita router models RD1101, RF1101, and RP1101. That means the fitment is the story here, not universal compatibility. If you use one of those Makita routers for edge work, dadoes, or inlay routing, this base is a direct match for that platform.

The Makita 193155-9 2-1/2" Clear Sub Base makes the most sense for woodworkers, trim carpenters, cabinet installers, and serious DIY users who already own one of the supported routers and want a clearer view of the cut. It is not flashy, but it is the kind of accessory that helps with precision, especially when the work is small enough that visibility and control matter more than raw power.
