Supermarket & Retail Square Tube Dual-Line Universal Hook

L:100/150/200/250/300/350/400(mm)

Core Advantages

    Universal square tube mounting system: Base fits common square tube sizes (25×25mm, 30×30mm, 40×40mm) via U-bolts, clamping plates, or brackets—no drilling required.

    No hole-position restrictions: Can be installed at any height on square tube uprights, independent of factory pre-punched hole spacing. Suitable for non-standard or aging shelf systems.

    Dual-line suspension arm: Two parallel wires connected by transverse ribs, providing higher bending stiffness and lateral stability than single-wire hooks.

    Graded length selection: Seven fixed lengths covering short-reach small items to long-reach large-pack products.

Product Features

    Square tube base specifications: Base made from short metal square tube segments or stamped components. Inner width customizable to match different outer tube dimensions. Fixing methods include U-bolt clamping, dual-plate through-locking, or welded backplate with screws.

    Dual-line arm structure: Two parallel main wires with 15mm–25mm spacing, connected by 2–4 welded transverse ribs. Wire diameter range: 5.0mm–6.5mm (selectable).

    Material & finish: Carbon steel. Consistent finish on base and arm, with options including electro-galvanizing, hot-dip galvanizing, or black electrophoretic coating.

    Tip anti-slip design: Front end of dual-line arm bent upward (angle 20°–35°), burr-free.

    Label attachment: Dedicated price label holders fit between the two wires, or clip-on holders attach to either wire.

Application Scenarios

    Square tube shelf retrofits in supermarkets: Add hanging display functionality to existing square-tube upright shelves without replacing the entire system.

    Side-mounting on retail display stands: Attach to the square tube sides of standalone display stands for accessories, promotional items, or cross-sell products.

    Endcaps of warehouse shelving: Mount on square tube uprights at pallet rack ends to expand endcap display area.

    Temporary promotional displays: Quickly add or remove hooks on modular square tube display frames to adapt to promotion cycles.

Common Issues & Solutions

    Issue: Can the square tube base fit different brands’ tube sizes?
    Solution: Measure the actual outer dimensions (width×height) of the target square tube before ordering. Standard base adjusts to a 25–45mm range. For values outside this range, customize the base inner width. For radius-corner square tubes, add rubber pads under U-bolts to conform to curved surfaces.

    Issue: Will the hook rotate or loosen after installation on a square tube?
    Solution: Ensure sufficient tightening torque on U-bolts or clamp plates. Use anti-slip washers or thread-locking fluid. For frequent product changeover, select base designs with locating pins and pre-drill a small pilot hole (3–4mm diameter) in the square tube.

    Issue: What is the load capacity of the dual-line arm?
    Solution: For 6mm wire diameter and 250mm length, reference static load capacity is 10–15kg under uniform loading. The actual upper limit depends on the tightness of the square tube base. Perform a manual push test after installation to confirm no visible base movement.

    Issue: Can the hook be installed at a square tube corner?
    Solution: Corner installation (intersection of two perpendicular faces) is possible with narrow-base or offset-base designs to avoid interference. Derate load capacity to 70% of the standard value for corner installations.

Product Precautions

    Square tube dimension verification: Measure actual outer dimensions and wall thickness before ordering. For thin-wall tubes (<1.5mm), U-bolt tightening may cause indentation—use interior sleeve reinforcement or clamp-plate fixing instead.

    Mounting height planning: Arm length and installation height must ensure that the suspended product’s bottom clears the lower shelf or floor by at least 150mm to avoid customer retrieval interference.

    Environmental suitability: For high-humidity areas (fresh produce, refrigerated sections), specify hot-dip galvanizing (≥45μm coating thickness) or stainless steel versions.

    Regular inspection: Check U-bolts or clamp plate tightness, as well as weld points between the dual-line arm and base, every 3 months.

    Avoid over-torque: The square tube base has a maximum recommended tightening torque. Do not use extended wrenches to over-tighten, as this may damage the tube or base threads.
