These nets have a black, anodized, aluminum frame with a soft, 3/16” mesh netting to protect trout. The netting in these Alumaguard nets is on the inside of the hoop ring to protect it from rocks and other foreign objects. Models 231 and 232 have shallow nets so fish can be cradled, unhooked and released. Both also feature a rubberized hand-grip and an 18" elastic cord. Model 231 is also a perfect live-well net.
