Have you ever spent more time than you would like adjusting, and re-adjusting a feather board? Sometimes it seems like a high price to pay for safety, doesn’t it? You won’t be tempted to work unsafely when you add these unique feather-boards to your router or table saw. A patented “short finger” on the leading edge helps you properly position the guide to apply the correct amount of pressure against the fence. That makes potentially dangerous woodworking operations both safer and more accurate. Feather-Locs can be used as hold downs, edge guides, stop blocks, or router table starting pins. Attach to standard 3/8" x 3/4" T-Track router table miter track slots using the 1/4" hex head bolts, or with the Slot Adapter for table saws and router tables that have plain miter slots. Made in the USA of a high tech reinforced polymer.
