CL128-2 White Zinc Plated Steel Lift-off Detachable Cabinet Hinge

CL128-2 White Zinc Plated Steel Detachable Lift-off Industrial Cabinet Hinge

CL128-2 is the upgraded extended model of CL128 series lift-off hinges, manufactured from stamped carbon steel with uniform white zinc electroplating anti-corrosion treatment. It adopts a split separable pin structure with no fixed opening angle limit for free rotating movement, equipped with two symmetrical mounting holes for firm installation. The overall installation width ranges from 58.5mm to 68.5mm, perfectly compatible with thicker frame sheet metal cabinets, electrical control enclosures, mechanical equipment protective covers and outdoor distribution boxes.

Detailed Technical Parameters

• Model Number: CL128-2
• Raw Material: Carbon Steel (Hinge Body + Integral Pivot Pin)
• Surface Finish: White Zinc Plated (Electro-galvanized)
• Rotation Mode: 360° free rotation, no built-in 90° limit stopper
• Mounting Holes: 2 round fixing holes
• Adjustable Installation Width: 58.5mm ~ 68.5mm
• Overall height dimension: 61.5mm
• Structure Type: Vertical split lift-off removable hinge

Whole cold-rolled steel stamping forming delivers high structural strength and strong load-bearing capacity for medium and heavy cabinet doors. White zinc plating effectively isolates air and moisture to prevent surface oxidation and rust, achieving excellent cost performance compared with stainless steel hinges for indoor dry working conditions. Different from CL128-1 with 90° stop, CL128-2 cancels the angle limiting block, allowing the cabinet door to rotate freely to any angle and directly lift off from the frame without disassembling screws, greatly simplifying equipment internal wiring, component maintenance, cabinet overhaul and door replacement work. The two-hole symmetrical layout ensures balanced stress during opening and closing, avoiding unilateral deflection and shaking of the door panel during long-term frequent use.

Core Product Competitive Advantages

1. Free Rotation Without Angle Restriction No built-in stop block, the door can be flipped arbitrarily, suitable for scenarios requiring large opening range, inspection and full door disassembly, more flexible than limited-angle hinges.
2. Split Lift-off Quick Disassembly Core Structure Upper and lower hinge halves can be completely separated, lift the door upward to detach directly, zero tool operation, extremely convenient for after-sales maintenance and production line assembly.
3. White Zinc Plating Economical Anti-Rust Coating Electro-galvanized white zinc layer has stable anti-corrosion performance in indoor, factory workshop and dry semi-outdoor environments, greatly reducing overall cabinet hardware procurement cost.
4. Wider Adjustable Installation Span 58.5–68.5mm adjustable installation width adapts to thicker cabinet frames and customized bending sizes, covers more non-standard sheet metal cabinet specifications.
5. High-Rigidity Stamped Steel Integrated Body Integrated bending and stamping process eliminates loose splicing risks, resists deformation under vibration and heavy load, durable for long-term cyclic opening and closing.

Main Application Industries & Scenarios

1. Low-voltage electrical control cabinets, frequency converter boxes, PLC automation equipment enclosures
2. Network server cabinets, industrial computer chassis, instrument test boxes and terminal junction boxes
3. Outdoor photovoltaic combiner boxes, street light power distribution boxes and waterproof metal electrical housings
4. CNC machine tool safety guards, automated production line protective casings and hydraulic equipment shells
5. Workshop industrial tool cabinets, dustproof storage boxes and mechanical engineering equipment covers

Installation & Selection Guidance

1. Use standard machine screws matching the hole diameter for locking, two hinges symmetrically installed for wide heavy doors to balance load.
2. Distinguish from CL128-1: Choose CL128-2 if free rotation and full door removal are needed; pick CL128-1 for 90° limited opening to protect internal wiring.
3. White zinc plated steel version is not suitable for coastal high humidity, salt fog and strong corrosive environments, select stainless steel hinges for those harsh conditions.
4. Verify cabinet frame installation groove width falls within 58.5~68.5mm before bulk order to avoid dimensional mismatch.

Product Summary

To sum up, CL128-2 white zinc plated steel free-rotation lift-off hinge complements the CL128 series product line together with CL128-1. It focuses on flexible free rotation and full quick door disassembly demands of industrial sheet metal cabinets, featuring separable lift-off structure, wide adjustable installation range and cost-effective zinc anti-rust surface, becoming a universal standard hardware for electrical enclosures and mechanical equipment boxes.
