Most farmers rely on nylon rope knots (which degrade and break in 3 months of saltwater exposure) or galvanized iron clips (prone to rust jamming, making repeated use impossible). This leads to devastating issues: HDPE oyster mesh bags tear at seams, cylinder tumbler splices split, and up to 8-12% of oyster seeds escape. Replacing these faulty connectors monthly adds unnecessary labor and material costs.
Our 316 Stainless Steel Oyster Bag Shark Clip (3*110mm) eliminates these risks with targeted design:
Anti-Slip Bite Teeth: 5mm-deep, 2mm-spaced teeth grip 1-5mm thick HDPE mesh (the material of our HDPE Oyster Grow Bag and Cylinder Oyster Tumblers) tightly—even after years of seawater immersion, no slippage occurs.
Anti-Jam Spring Technology: The clip’s spring uses a precision winding process that resists saltwater corrosion. It maintains stable clamping force even after 1,000 openings and closings, with a 95%+ reuse rate (vs. 0% for rusted iron clips).
The Problem
Emergencies like typhoon prep or low-tide sorting demand speed—but wet hands + complex rope knots/bolts slow work to a crawl. On average, 1 worker can only secure 20 HDPE Oyster Mesh Bags or Hexagonal Oyster Baskets per hour. In tide-sensitive regions (e.g., Brittany, France; Rushan, China), delayed adjustments often mean missed windows to protect stock.
The Shark Clip Solution
Designed for one-handed, tool-free use, our 3*110mm shark clip solves this:
Ergonomic 45° Opening Angle: Even with wet gloves, workers can snap the clip open/closed in 2 seconds—no fumbling with knots or wrenches.
Low Force Requirement: Requires ≤15N of pressure to operate (about the force of lifting a 1.5kg bag), reducing hand fatigue during long shifts.
The Value
Efficiency jumps to 80 bags/baskets per worker per hour—4x faster than traditional methods. Farmers in high-tide areas now meet emergency prep deadlines (e.g., securing cylinder tumblers before storms) without extra labor.
Pain Point 3: Poor Compatibility—Multiple Connectors for Multiple Gear
The Problem
Oyster farms rarely use just one type of gear: HDPE Oyster Mesh Bags(1-2mm thick) for seeding, Cylinder Oyster Tumblers (3-5mm thick) for grow-out, and Hexagonal Oyster Basket (4mm thick) for harvesting. Traditional setups require 3+ different connectors, leading to overstock, storage chaos, and last-minute runs to replace missing parts—especially for small-to-medium farms.
The Shark Clip Solution
Our 316 Stainless Steel Shark Clip (3*110mm) is a “one-clip-fits-all” solution:
Wide Clamping Range: Adapts to 1-5mm thick materials, perfectly fitting all three core gear types.
Universal Design: Works for sealing mesh bag tops, splicing cylinder tumblers, and securing baskets to rafts—no need for specialized clips.
The Value
Farms eliminate 60% of connector inventory, cut storage costs, and avoid downtime from missing parts. Small operations, in particular, benefit from simplified purchasing (one clip for all gear) and easier inventory management.
