CL152-1 Brushed Stainless Steel Thin Flat Butt Free Rotation Industrial Cabinet Hinge

CL152-1 is a miniature flat butt hinge made of solid stainless steel with matte brushed grinding finish. It features a slim 2mm thick hinge leaf, symmetrical 4-hole countersunk mounting layout, precision machined central pin for seamless 360° free rotation without opening angle limitation. Compact overall size and minimalist flat structure make it ideal for small electrical boxes, instrument casings, control panels, plastic enclosures and light-duty equipment flip covers.

1. Material & Surface Treatment Advantages

Genuine stainless steel raw material delivers excellent rust, oxidation and weak chemical corrosion resistance, suitable for damp indoor workshops, light outdoor sheltered environments and electronic equipment with strict anti-rust requirements. Brushed grinding surface effectively resists fingerprint marks and minor surface scratches, maintains neat appearance for long-term use, better durability than polished finish for industrial equipment.

2. Ultra-Thin Flat Compact Structure

Only 2mm leaf thickness greatly reduces overall installation protrusion, saves cabinet internal assembly space, avoids interference with internal wiring, circuit boards and components. Symmetrical rectangular two-leaf design ensures balanced stress distribution during opening and closing, stable operation without deflection.

3. 4-Point Countersunk Flush Installation

Standard 90° countersunk hole design allows flat head screws to be fully embedded inside the panel, creating a completely flat exterior surface, eliminating protruding screw heads that cause scratching or collision damage. Four evenly spaced mounting points disperse load evenly, prevent hole deformation or pulling out on thin metal, aluminum and plastic plates.

4. Smooth Full-Angle Free Rotation

Precision fitted hinge pin rotates silently and smoothly, no jamming or wobble. Without built-in limit stoppers, the door panel can be fully flipped open to 360 degrees, providing unobstructed access for internal inspection, wiring modification, component replacement and equipment maintenance.

Core Selling Points

1. Anti-Corrosion Stainless Steel Body Strong rustproof performance, adapts to humid working environments and electronic equipment protection.
2. Matte Brushed Anti-Fingerprint Finish Resists daily scratches and fingerprints, long-lasting clean industrial appearance.
3. Slim 2mm Thin Flat Profile Space-saving installation, no internal component interference inside compact casings.
4. 4-Hole Flush Countersunk Mount Hidden screw installation, smooth exterior surface, firm anti-loosening fastening.
5. 360° Unrestricted Free Rotation Full opening access for convenient equipment overhaul and routine maintenance.

Typical Application Scenarios

1. Small electrical control boxes, PLC junction boxes, sensor signal transmission enclosures
2. Laboratory testing instrument shells, portable detection device flip covers
3. Aluminum alloy equipment cabinets, desktop industrial computer side panels
4. Plastic waterproof distribution boxes, communication terminal wiring housings
5. Light-duty workshop tool boxes, automation small module protective covers

Installation & Selection Guidelines

1. Load Scope: Designed for light-weight small door panels only, not applicable for heavy large cabinet doors.
2. Screw Matching: Use 90° countersunk flat head screws to match the Φ7.5 sink holes for fully flush installation.
3. Quantity Matching: For slightly wider door covers, install two CL152-1 hinges symmetrically to share bearing stress.
4. Rotation Reminder: This model has no fixed opening stop, assess swinging collision risks before bulk purchasing.
