|Although only a simple piece of kit, this little adapter will make the job of tying tubes much less stressful. Fits into the jaws of a standard tying vice. The tapered collet allows good access to the tube unlike some other adapters on the market.Much more stable way to make tube flies than the classic darning needle approach. Comes with three different ’needles’ to accommodate large and small bore tubes. Mount the tube onto the needle and press into the collet and tighten the screw.
