Big Horn 19668 Brass Router Template Guide I.D. 17/32" O.D. 5/8" Lock Nut

Router Template Guide for Controlled Cuts

This brass template guide fits a router base to keep the bit a fixed distance from a pattern edge while cutting the workpiece. It replaces Porter Cable 42045 and pairs with the included lock nut for secure attachment. Woodworkers who follow templates for repeatable profiles will find it useful.

Brass Construction Resists Wear Under Continuous

The solid brass body withstands prolonged contact with templates and workpieces without the deformation that softer alloys can show during long sessions. The lock nut uses a knurled surface for hand tightening so the guide stays fixed when the router runs for extended periods.

Low Friction Reduces Heat

Brass-on-template contact generates minimal heat compared with steel alternatives, keeping the bit path stable and the cut quiet during normal feed rates. No external power draw or active cooling is involved, so the accessory adds no electrical load to the router.
