The Longboard Fin Channel Install Kit is designed for installing standard center fin channels. Thick aluminum plate, with non-slip rubber mat on the bottom. Metal construction never wears - built to last a lifetime.
Uses common 1/2" diameter x 1" length, top-bearing flush trim bit. Produces a professional tight, 1/16" margin for resin around the sides of fin channel.
101 Tip - Always make multiple depth cut passes (ie 1/2", then 3/4") rather than attempting to cut the full depth at once. Also work slowly through stringer to avoid splintering. The top-bearing runs along inside of jigplate just like FCS II / Fusion installation.
