They come in 3 different shaped net frames. The round Belmont, the "D" shaped Seaforth and, finally, the bow shaped Errol.
Each frame is 16"wide and has an overall reach of 52" that when folded is 20". The net is approximately 14" deep with a pan shaped bottom that is 15" wide. The net bag is a woven combination of D210, D400 and D600 polyester that is both strong, yet soft to touch and is mildew resistance. It is resistant to stretching, shrinking and resists pilling (bobbling).
The photograph show both the Lakeside 16 (on the right) and Lakeside 20 with these net bags; this page is for Lakeside 16 landing nets only.
