Big Horn 14102 Clear Router Sub Base for Routers 100, 690, 691, 693

The Big Horn 14102 is a transparent router sub-base crafted for greater visibility and precision, especially when working on inlays, edge routing, or dadoes. Its crystal-clear plastic design lets you see your workpiece underneath, improving accuracy and control. The sub-base features a generous 2-1/2" center hole, allowing it to accommodate larger router bits than standard opaque bases. It’s compatible with Porter-Cable routers—specifically models 100, 690, 691, 693—making it a reliable OEM replacement for base number 42188. Installation is straightforward, as it uses your router’s existing mounting screws with no need for modifications. Built from sturdy, impact-resistant acrylic, the 14102 base delivers long-term durability while maintaining a lightweight profile.
