The WINDER fits on 85% of all fly reels produced world-wide! The soft rubber does not harm the fly reel's finish.
Most reels equipped with a cylindrical counter-weight will find their matching pairs of slots on the winder.
The WINDER is NOT suited for fly reels without or with odd-shaped counter weights, nor for anti-reverse reels (special shaped handles).
For very large off-shore reels, pre-traced slots can be cut out, using a sharp knife and a round file.
Customizing the shape of certain holes to fit your reel's handle, is very easy with a round file or a sharp knife.
