The Makita 321492-3 Template Guide Adapter is a router accessory built to let compatible Makita routers use a 2-piece template guide. This is a template guide adapter designed for template routing and guided pattern cutting. Model Number: 321492-3. If you need your router to follow templates for repeatable cuts, sign work, jig work, or guided edge shaping, this is the part that makes that setup possible.

What matters here is function, not flash. The adapter mounts to the router so you can use the corresponding template guide and template guide nut. That gives you a stable way to track a template while the bit does the cutting. In practical terms, it helps you make cleaner duplicate parts, follow sign-making templates, and run guide bushing setups that would be difficult or inconsistent freehand.

Makita calls out easy installation, and that is a real benefit on a small accessory like this. Nobody wants to turn a simple router setup change into a half-hour project. If your work switches between freehand routing and guide-based routing, quick attachment matters because it keeps the router useful for more than one kind of job without wasting time.

The metal construction is another point worth paying attention to. A template guide adapter needs to stay true and hold its shape because the whole point is controlled routing. A solid metal part is better suited for repeated mounting, removal, and jobsite or shop use than a lighter-duty alternative. When the guide system fits right and stays put, your router follows the template the way it should.

Compatibility is the key buying decision with this part. It is for use with several Makita routers, and Makita specifically lists compatibility with router models 3606, 3612, 3621, and 3620. It is also intended for use with the corresponding template guide and template guide nut, so this is part of a routing system rather than a standalone accessory.

This Makita router guide adapter makes the most sense for woodworkers, cabinet installers, trim carpenters, and serious DIY users who already own a compatible Makita router and want to do more precise template-guided work. If you are cutting repeated shapes, routing from jigs, or using template bushings for cleaner, more controlled results, this is the kind of small part that solves a real problem. If you do not use templates or guide bushings, you probably do not need it. If you do, you definitely do.
