Stonfo Joint Block

Stonfo Joint Block is an articulated mounting block that adds positions for up to four accessories used at the same time. It clamps directly onto the fly-tying vise stem, allowing a bobbin rest or other compatible supports to be arranged close to the working area. The jointed construction makes it easier to position the accessories to suit the tying method and layout of the workstation.

The block is designed for vise stems measuring 8–10 mm in diameter, including 3/8 inch stems. The supplied adaptor bush is used when fitting it to an 8 mm stem, while the included Allen key secures the mounting mechanism. Before final tightening, set the block at a convenient height and check that the attached items do not restrict access to the jaws or movement of the vise head. The pack contains one Stonfo Joint Block, an 8 mm adaptor bush and an Allen key; the vise and working accessories are not included.
