These net bags are designed to fit the large sized surber frame. They connect to the frame by threading onto an inner brass ring which is then attached to the main frame using a series of brackets, held in place with nuts and bolts. This clever design prevents the net collar from rubbing on the river substrate and so helps to reduce wear and tear. The collar is made from strong nylon which also helps to improve longevity. The end of the net is fitted with a removable screw-on filter which has the same mesh size as the main part of the net.
Available with 250µm, 500µm or 1mm mesh.
