HDPE Coated Multifilament 21-Ply Vertical Folding Trap Net — For Crab, Shrimp, Eel

Bottom traps sit in mud, silt and brackish water — and those two conditions attack netting differently: mud abrades, while low-oxygen water lets rot take untreated nylon. The yarn in this trap is 21-ply HDPE with a plastic coating, so the twine is sealed against rot and stiff enough to hold its mesh shape when the trap is hauled half-full of mud.

Coated Yarn, Stiff Mesh

• HDPE-coated 21-ply yarn — the coating seals out waterlogging and rot; bare multifilament goes soft and slimy in brackish ponds
• Vertical folding steel rings — collapse flat for stacking, hold a rigid column when set
• Double-knotted throughout — traps get dragged and dropped; knots keep the mesh geometry under stress
• Central bait pocket — bait stays centered, so animals commit to entering rather than picking through the mesh
• Multiple diameters and heights — match trap volume to your species and hauling method

Freshwater vs Brackish Service

The coated twine pays for itself in muddy ponds and brackish water, where rot — not tearing — is what retires most traps. On clean rocky bottoms the coating matters less and frame strength matters more, so we size the steel ring accordingly. Set on soft bottom, check daily in warm water, and fold the trap vertically after hauling so the mesh dries instead of sitting wet in a heap — that is the single cheapest way to stretch service life.
