CL225-1 Spring Loaded Drop Pin Hinge

Basic Technical Parameters

  • Main Model: CL225-1
  • Material: Full cold rolled steel, plate thickness t=2mm, pin diameter Φ6mm
  • Surface Treatment: White zinc electroplated plating (anti-rust, anti-oxidation)
  • Total Overall Height: 89mm, horizontal width 25.4mm
  • Structure Type: Spring loaded compression rebound barrel hinge, vertical drop pin lift-off design
  • Version Classification (Left / Right Hand + Hole Option)

Core Competitive Advantages

1. All-Steel Heavy-Duty Structure

Whole body stamped and machined from solid steel plate (2mm thick), solid Φ6mm steel locating pin, strong shear resistance and load-bearing capacity, not easy to deform under heavy cabinet door weight, far more durable than zinc alloy hinges for frequent use scenarios.

2. White Zinc Plating Anti-Corrosion Protection

Uniform white zinc electroplated layer effectively isolates air and moisture, prevents rust and oxidation, excellent performance in damp indoor workshops and mild semi-outdoor environments, prolong service life of cabinet hardware.

3. Built-In Spring Automatic Rebound Lock

Internal compression spring provides constant tension, after inserting the locating pin, the spring automatically locks the pin in position to prevent accidental falling out during door opening/closing, improves safety and avoids door falling risk.

4. Dual Installation Versions for Flexible Selection

  • Non-hole version (CL225-1-Z/Y): Welding fixed type, fully hidden installation, neat cabinet surface, suitable for welded sheet metal cabinets
  • Holed version (CL225-1A-Z/Y): 2×Φ5.5 through holes for screw fastening, easy disassembly and replacement, ideal for assembled equipment boxes

5. Left & Right Hand Symmetrical Matching

Independent left-hand and right-hand directional hinges, matched according to cabinet door opening direction, perfect for double-door cabinets, side opening equipment panels and split enclosure doors.

6. Tool-Free Quick Lift-Off Disassembly

Press the spring upward to retract the locating pin directly, lift the door off without any screwdrivers, greatly accelerate equipment maintenance, cabinet batch production and packaging transportation efficiency.

Main Application Scenarios

  1. Electrical control cabinets, low-voltage distribution boxes, PLC enclosures and power equipment protective doors
  2. Mechanical equipment safety guards, CNC machine tool casings, automation production line accessory boxes
  3. Network server cabinets, weak current integrated boxes, outdoor charging pile control enclosures
  4. Double-door sheet metal cabinets, instrument test equipment housings, communication equipment chassis
  5. Industrial equipment requiring frequent door removal for internal inspection and overhaul

Installation & Maintenance Guidelines

Installation Steps

  1. Confirm left/right hand direction and hole version according to cabinet opening requirement
  2. Hole version: Mark hole spacing 45mm vertically, drill Φ5.5 holes and fasten with bolts; Non-hole version: directly weld the base plate onto cabinet frame
  3. Compress the built-in spring, insert the Φ6 locating pin into the sleeve to complete assembly
  4. Test door swing, verify spring locking function and smooth lift-off detachment

Installation Quantity Suggestion

  • Single door height ≤ 600mm: 2 pieces of hinges symmetrically installed
  • Door height 600–1000mm or heavy metal door: 3 pieces for anti-sagging and balanced load bearing

Maintenance Precautions

⚠️ Not recommended for long-term exposure to strong acid/alkali corrosive environment, heavy dust and coastal salt fog atmosphere.

  1. Regularly wipe the zinc-plated surface with dry cloth to keep clean
  2. Add a small amount of anti-rust grease to the spring and pin joint every 3–6 months to ensure flexible rebound and smooth pulling
