Bow Products FeatherDuo Dual Featherboard Stack

Bow FeatherDUO Stackable Featherboard offers all the breakthrough benefits of the FeatherPRO featherboard in a raised platform. Ideal for feeding taller material on Table Saws, Band Saws and Router Tables. FeatherDUO includes two separate FeatherPRO featherboards along with two risers and long bolts for a maximum stackable height of 89mm (3.5).

FeatherDUO Features and Benefits:

Outstanding Feed Control: EVA Feathers are firm, yet pliable. EVA feathers are shaped to maximize feather surface contact on the material. These attributes combine to deliver a smooth firm glide under tension. A firm and controlled feed ensures a straight clean cut.
EVA Feathers Protects you Wood and Tools: EVA feathers are a high-density industrial grade foam material that even under highest tension will not mar or leave chatter marks on even the softest of woods. EVA feathers will also not wear or bleed onto material. EVA feathers dampen vibration for a cleaner cut. In the event of accidental contact with a cutter, unlike plastic feathers that can damage cutters and become dangerous projectiles, EVA feathers will cut right through.
Unprecedented Kickback Safety: If there is one reason to buy the FeatherDUO over any other featherboard, it is your safety. Patented hinge design combined with the EVA feathers ability to absorb energy provide than 5X more resistance against kickback than plastic or wood feathers. As kickback occurs and material moves backwards, the hinged feather opens and applies pressure on the material against the fence. EVA Feathers simultaneously absorb energy to reduce or even arrest kickback.
Reversable, Replaceable and Interchangeable Feathers: Bow feathers are press-fit into the FeatherDUO and reversible for left or right feed. If accidentally damaged, simply buy a replacement feather. FeatherDUO comes with our UltraFLEX feathers. Standard or Ultraflex feathers available as replacements separately.
