Guide Rail Adapter is a great addition to your router accessories!

Guide Rail Adapter: Its mounting holes perfectly align with the router. Use this adapter for straight and precise cutting work, with tracks and saws, clean cutouts, and straight V-grooves and wainscoting cutouts, without handling clamping or tightening warped wood!

Router parts eliminate the need for cumbersome bases, and can be quickly interchanged with the original base when needed, using rails as rulers. It's not as polished or precise as some of the more professional bases, But it is enough to make up for this in the time saved.
