Owner SBL-31 Single 31 Barbless 8 11614

The same form as the S-21, but the power glasses are "3". The S-31BL is made to be slightly thicker and barbless (BL). Though the narrow axis specification, the exquisite wire diameter setting can be used for Donaldsons over 19.7 inches (50 cm) if interacted successfully, it is obviously different from the S-21. It is also effective for instant shooting bites. barbless
