Bitzenburger Fletching Jig Upgraded Nock Receiver by Zenith Archery

Zenith Archery Products Bitzenburger Upgrade Kit Zenith Archery Products has introduced a new upgraded nock receiver for your Bitzenburger fletching jig. The replacement body will fit directly into your jig and will still adjust for all three different fletching patterns. The original receiver held the arrow only by a loose fit on the nock. The new receiver comes with two inserts which are held into the body by a long screw which is tightened through the rear of the receiver and will hold the arrows directly, without slippage. One insert is sized to fit snuggly into any arrow which uses a G nock.  The second insert does arrows which use pin nocks, holding the pin by the hole in the insert. It also does arrows which use Super nocks (.246 carbon, Super Uni-bushings, etc.) by fitting the insert into the back of the arrow. If the pin holder becomes too loose, just gently squeeze the segments together with a small plier until it holds the pin tightly again.  This kit DOES NOT include a sleeve for X or H nocks.  These are available as an option if needed.  An adjustable upper support plate is mounted using the template and hardware included with the kit. Once the arrow is mounted in the jig, the plate is adjusted to support the upper end of the shaft. Older arrows with glue on nocks can still be done using the old receiver.  This will not work with crossbow bolts.  There was a change in design by bitzenburger around 25 years ago and this may not work with jigs older then that.

    Bitz Kit

    Posted by Jeff Powelson on May 22nd 2018

    Stock Bitz jig had a “hope this spacing is close” tolerance with many refletches needed. Did a few arrows with the Zenith and was so amazed at accuracy that I refletched all my arrows! All came out perfect. Used small nock pin adaptor with no problems

    works great

    Works great. The instructions leave something to be desired. In addition a screw was missing. I emailed and got help with instructions and they sent screw overnight. A utube video would be nice.

    Bitzenburger Upgrade

    Posted by Ward on May 22nd 2018

    This upgrade takes your Bitzenburger to the next level adding precision for those archers desiring perfection. Installation is relatively simple. Once installed the only added time is removing the arrow nock to insert the upgrade kit “pin” into the inside of the arrow, nock end. Make sure you insert arrows to the same depth. I’ve used successfully with X (0.204″ ID) and G (0.166″). Great product, and have no plans to revert back to the Bitzenburger standard.
