Our aluminum-encased Whisker Biscuits are 300% stronger than previous models. And, we've added a rock-solid, dual-bolt mount and a set screw* for even more secure, "locked-down" mounting. The Whisker Biscuit's design makes setup easier than ever before. Attach the Whisker Biscuit to your riser mounting holes and it automatically lines up the arrow rest. And most models are designed for use with left and right hand bows. Its lightweight, compact design provides maximum clearance around quivered arrows.
