CL130-2 / CL130-2S 90 Degree Limited Lift-off Cabinet Hinge

CL130-2 CL130-2S 90 degree limited lift-off hinge steel SUS304 white zinc plated

CL130-2 is a horizontal split lift-off hinge with built-in 90-degree angle limiting function, launched in two material grades to adapt different working environments: CL130-2 (Carbon Steel, White Zinc Plated) and CL130-2S (SUS304 Stainless Steel, Natural Polished Finish). It adopts embedded bending structure matched with standard cabinet door & frame installation size, equipped with 90° mechanical stop to prevent over-rotation, countersunk hidden screw holes for flat surface, and separable pin for quick door disassembly. Widely used in electrical control cabinets, outdoor distribution boxes, instrument enclosures, and waterproof sheet metal equipment housings.

Detailed Technical Parameters

• Model Series: CL130-2 (Steel) / CL130-2S (SUS304 Stainless Steel)
• Raw Material Option 1: Cold Rolled Carbon Steel Surface: White Zinc Electroplated
• Raw Material Option 2: SUS304 Stainless Steel Surface: Natural Matte Raw Color
• Fixed Opening Angle: 90° mechanical limit stop
• Overall Outer Dimension: 65mm total length
• Mounting Holes: 2 × Φ6.7 countersunk holes (12.7×90° countersink) 2 × Φ5.1 through holes
• Core Structure: Horizontal split lift-off removable hinge
• Mounting Adaptation: Precisely positioned for conventional bent sheet metal door panels and cabinet frames

Integrated stamping and bending forming delivers high structural strength and stable load-bearing performance for medium-weight cabinet doors. The built-in blocking structure strictly locks the door at 90 degrees after opening, effectively avoiding excessive swing that pulls internal wires, damages electrical components or scratches the cabinet body. The lift-off split pin enables tool-free removal: lift the door upward directly to separate two hinge halves, greatly simplifying equipment wiring, component replacement, cabinet maintenance and on-site after-sales service. Two material versions cover different cost and corrosion resistance demands:

1. Carbon steel CL130-2 with white zinc plating: cost-effective choice for indoor dry workshops, dust-free electrical rooms and non-corrosive indoor environments.
2. SUS304 stainless steel CL130-2S: excellent resistance to rust, moisture, water splash and weak acid/alkali, applicable to outdoor boxes, coastal salt fog atmosphere, food machinery and wet production workshops. Countersunk 90° recessed holes allow screw heads to sink completely into the hinge surface, keeping the cabinet exterior smooth and neat without protruding obstacles.

Core Competitive Advantages

1. Built-in 90° Angle Limit Protection Fixed stop mechanism restricts maximum opening at 90°, the most safety-focused design for electrical cabinets to protect internal wiring and devices.
2. Two Material Grades for Full Scenario Coverage Economical white zinc plated steel for indoor standard cabinets; SUS304 stainless steel for outdoor, humid, corrosive and high hygiene requirements.
3. Hidden Countersunk Screw Installation 90° countersunk holes eliminate protruding screw heads, improve cabinet appearance and avoid accidental scratching during operation.
4. Tool-Free Lift-off Quick Disassembly Horizontal separable pin structure realizes fast door mounting and removal, improves production line assembly efficiency and maintenance convenience.
5. Standardized Sheet Metal Matching Dimensions All bending and installation sizes are optimized for common cold-rolled steel cabinet frames, no secondary cutting or modification needed during installation.

Main Application Fields

1. Low-voltage electrical control cabinets, frequency converter boxes, PLC automation control enclosures
2. Outdoor photovoltaic combiner boxes, street lamp power distribution boxes, rainproof metal junction boxes
3. Medical instrument cabinets, testing equipment housings, laboratory dustproof protection boxes
4. Food processing machinery casings, marine weak current boxes, coastal anti-corrosion equipment enclosures
5. Network server cabinets, industrial computer chassis and factory workshop safety guard covers

Installation & Selection Guide

1. Environment Selection Rule: Choose CL130-2 steel version for dry indoor only; select CL130-2S SUS304 for outdoor, high humidity, salt fog, water splash and corrosive sites.
2. Hole Matching: Use flat head screws for Φ6.7 countersunk holes, round head screws for Φ5.1 through holes for flush mounting.
3. Load Suggestion: Install two CL130-2 hinges symmetrically for wide or heavy cabinet doors to balance bearing force.
4. Angle Feature: This model is fixed 90° opening only, cannot rotate 180°, confirm opening demand before ordering.

Product Summary

In short, CL130-2 dual-material 90° limited lift-off hinge complements the CL130 series industrial hinge lineup. It integrates angle safety limit, quick detach lift-off function and hidden countersunk installation, solving both cost control and anti-corrosion durability problems for indoor & outdoor sheet metal cabinets, becoming a universal standardized hardware for electrical enclosure industry.
