The Bohning Zen Vane was developed specifically for Indoor Target Archery. Its low clearance height (.37") allows for clearance on tight setups with larger shafts (.25 and .27). This vane is 4 inches long providing the preferred surface area to stabilize large diameter arrows in short distances. The AR1000 Material is Bohning's original vane material that provides for excellen adhesion and durability, while being extremely forgiving for any potential contact. All Bohning vanes are pre-primed and do not require vane cleaning or pen primers. For our most durable and flexible adhesion, Bohning suggests using Fletch-Tite Platinum® for our AR1000 material. If faster cure times are needed, we recommend BlazerBond® or Fletch Fuse® adhesives.
