Weights, swivels and snaps are critical parts of a catfish rig. They must cope with bait weight, current and the load generated by powerful fish, so select components as one balanced system.
Choosing the weight
Match sinker weight to current, depth, bait and the rod's casting rating. Too little weight may not hold position, while excessive weight can exceed rod limits.
Swivels and snaps
Consider rated strength as well as physical size and closure design. Swivels reduce line twist, while a secure snap can make changing components quicker.
