A stone rig uses a natural stone as a single-use weight, tied to the main line with a binding cord that releases after the take. The Stone Rig Line is made to hold the stone reliably while the rig is in use and to disappear afterwards, unlike standard nylon or braid.
Yes. Sisal is a natural plant fibre, and after a few days submerged the cord dissolves completely and in an environmentally friendly manner. No synthetic residue stays on the bottom.
Choose 2 mm / 100 m for medium stones and standard Wels presentations — you get up to 100 rigs per spool. Pick 3.2 mm / 70 m when you tie heavier stones, fish strong current, or want extra safety reserves during the cast.
Black Cat states up to 70 stone rigs from the 3.2 mm / 70 m spool. The thinner 2 mm / 100 m spool gives more length for more rigs per spool, depending on how much cord each stone requires.
Keep the spool dry until you need it. Sisal fibres only start to break down once they are wet, so dry storage preserves full strength for the session.
No. The Stone Rig Line is a binding cord for the stone only. Use a proper catfish main line or shock leader for the main connection to the rig.

The Black Cat Stone Rig Line is a natural-fibre sisal cord designed for tying stone rigs and sinker rigs (back lead rigs) when targeting Wels catfish. After the fight the line is left behind on the bottom, where it dissolves completely and in an environmentally friendly manner within a few days.
Stone rigs use a heavy natural stone as a non-retrievable weight, held by a breakable binding cord. The Stone Rig Line is engineered exactly for this job: strong enough to hold the stone through casting and the initial take, yet biodegradable so nothing persistent is left in the water.
Made from sisal, the cord offers excellent knotting properties and a high breaking strength under dry conditions. Once submerged for a few days the fibres break down naturally, which is why Black Cat recommends keeping the spool dry until the session.
The 2 mm version on a 100 m spool suits medium stones and everyday Wels fishing; the thicker 3.2 mm version on a 70 m spool gives extra reserves when binding larger stones or fishing heavier current. Choose the diameter according to the size and weight of the stone you plan to tie.
