The wide groove makes placing them on the line quick and easy. Another advantage is the increased surface area that grips the line. This prevents damage and also stops the Stotz pinging off under stress. The flat ends of Stotz produce a neat bulk when they are grouped together. The Stotta applicator has been developed to make the application of Stotz even easier. Designed to work with all sizes the flat end of the Stotta allows a Stotz to be selected and applied quickly and easily. The Stotta can also be used to quickly remove Stotz without damaging your line.
