Our Flatblade Duratube blanks feature a durability-enhancing 4lb density central box with a strike-friendly 2lb density blade edge. The external measurements on the blanks are 24" long, 2.6" edge-to-edge, and 1.5" thick flat-tp-flat. They come ready-to-use with a pre-placed .4" hole in the center suitable for use on cores up to .602" in diameter. Like all of our blade technology the Flatblade Duratube blank doesn't have any glue in the construction which increases durability and saves weight dramatically.
This is the ultimate in DIY flatblade materials. Build gear better than most professionals, for a fraction of the cost.
