CL132-2 Stainless Steel 90 Degree Limited Lift-off Cabinet Hinge

CL132-2 is a heavy-duty split lift-off hinge with 90-degree fixed opening stopper, entirely constructed from stainless steel and processed by electro polishing for superior rust resistance. It adopts a thickened folded U-type structure, equipped with Φ11 large-diameter rotating shaft for high load capacity, multi-specification mounting holes including M5 internal thread holes, and built-in mechanical limit block to lock door panel at 90°. The separable pin allows tool-free door removal, widely applied in outdoor distribution boxes, marine equipment cabinets, chemical anti-corrosion enclosures, food machinery and high-humidity industrial sheet metal housings.

Detailed Technical Specifications

• Model No.: CL132-2
• Material: Full Stainless Steel
• Surface Treatment: Electro Polished (Bright mirror finish, improved corrosion resistance)
• Limit Opening Angle: Fixed 90° mechanical stop
• Overall Length: 80mm
• Rotating Shaft Diameter: Φ11
• Mounting Hole Configuration: 3 × Φ11 countersunk holes, 3 × Φ5.2 through holes, 3 × M5 tapped threaded holes
• Structure Type: Horizontal split lift-off removable hinge
• Installation Matching: Standard bending size for sheet metal cabinet frame and door panel

Whole stainless steel one-piece stamping and bending ensures ultra-high structural rigidity, effectively resisting deformation under heavy load, vibration and frequent opening/closing cycles. Electro polishing removes surface burrs and forms a dense passive film, greatly enhancing anti-rust, anti-oxidation and anti-fouling performance, perfectly adapting to outdoor rain, water splash, salt fog, damp workshops and mildly corrosive gas environments that carbon steel hinges cannot withstand. The Φ11 thickened main pivot shaft drastically upgrades shear strength and bearing weight, runs smoothly without jamming or abnormal noise, ideal for heavier cabinet doors. The built-in limiting mechanism strictly restricts maximum opening to 90°, preventing over-swing from tearing internal wiring, colliding electrical components or damaging cabinet shell, which is critical safety design for electrical control boxes. Diversified hole layout brings outstanding installation compatibility: M5 threaded holes for direct screw locking without nuts, Φ5.2 through holes for bolt penetration, and Φ11 large countersunk holes for flat head screws, freely matching aluminum plates, stainless steel panels and thick cold-rolled steel frames.

Core Competitive Advantages

1. Full Stainless Steel + Electro Polished Premium Anti-Corrosion Electro polishing surface far outperforms zinc-plated carbon steel, suitable for outdoor, coastal, humid, food-grade and slightly corrosive harsh scenarios.
2. Φ11 Oversized Reinforced Shaft for Heavy Load Thickened rotating pin boosts load limit and service life, stable for large and heavy equipment cabinet doors.
3. Reliable 90° Mechanical Safety Limit Avoids excessive door rotation to protect internal circuits and devices, standard safety configuration for power distribution enclosures.
4. Multi-Type Composite Mounting Holes M5 threaded holes + through holes + countersunk holes three-in-one design, maximizes on-site assembly flexibility and reduces processing cost.
5. Lift-off Split Pin for Tool-Free Quick Disassembly Separate two hinge halves by lifting the door upward, greatly accelerating production assembly, equipment inspection, wiring maintenance and component replacement.

Main Application Scenarios

1. Outdoor photovoltaic combiner boxes, waterproof street light distribution boxes, rainproof power control cabinets
2. Marine electrical equipment housings, ship weak current junction boxes, offshore anti-corrosion metal enclosures
3. Food processing machinery casings, beverage production line protective covers, hygiene-grade stainless steel cabinets
4. Chemical workshop ventilation boxes, laboratory test equipment cabinets, wastewater treatment control boxes
5. Heavy-duty industrial server cabinets, large automation equipment protective shells, mechanical tool storage boxes

Installation & Selection Guidance

1. Environmental Selection: This all-stainless steel electro polished version is preferred for all damp, outdoor, salt fog, corrosive and hygiene-sensitive sites.
2. Hole Usage: Use M5 screws for tapped holes, round head bolts for Φ5.2 holes, countersunk flat screws for Φ11 recessed holes for flush mounting.
3. Load Installation: For wide or overweight door panels, install two CL132-2 hinges symmetrically to share bearing stress.
4. Angle Confirmation: Fixed 90° opening only, cannot rotate to 180°, verify required opening range before bulk order.

Product Summary

In conclusion, CL132-2 serves as the high-end heavy-duty upgrade model in the lift-off hinge product line. It integrates full stainless steel electro polished anti-corrosion treatment, oversized load-bearing shaft, 90° safety limit and versatile composite mounting holes, providing long-life, high-reliability hinge solutions for harsh working condition sheet metal cabinets and special industrial equipment enclosures.
