The Supa River holding net is very robustly constructed in every area, making it very suitable for use on canals and rivers with shipping. First of all, it is equipped with a CNC-milled metal block that is threaded in both horizontal and vertical directions. The coarse, rectangular mesh (6×9mm) is highly abrasion-resistant and, thanks to its relatively large openings, easily allows flowing water to pass through, making it less likely to be pulled from its place. The top aluminum ring is equipped with an enlarged diameter, while the other rings are individually equipped with a protective, wear-resistant layer. The bottom features 2 attachment points for adding weight if desired.
