Our Net Holder is 12″ to 16" long and is made with 2" tube (1-3/4" I.D.). It clamps to the tower leg with a machined aluminum clamp. The Net Holder has a stop welded at bottom to keep the net from dropping through. This Net Holder works well for trout nets and salmon nets. We do make a larger net holder with a 2″ I.D. for the extra large nets. Clamp sizes for 2″ or 2-3/8″ tower legs.  The Net Holder can be made with a plate to mount directly to the gunnel instead of a tower.
