1. Material & Surface Advantages

Stainless steel substrate delivers outstanding rust, oxidation and weak chemical corrosion resistance, suitable for damp workshops, semi-outdoor equipment and marine mild salt spray environments. Wire drawing polishing texture effectively resists fingerprints, surface scratches and abrasion, maintains neat metallic appearance for long-term frequent use, superior durability over mirror polished hinges for industrial scenarios.

2. 3mm Thick Reinforced Hinge Leaf

3mm solid thickened plate greatly improves bending resistance and load capacity, avoids deformation and sagging under the weight of medium-sized cabinet doors, stable long-term repeated opening and closing operation.

3. 8-Point Symmetrical Countersunk Flush Installation

8 evenly arranged 90° countersunk holes allow flat head screws to be completely embedded into the panel surface, keeping equipment outer shell smooth and scratch-free. Eight fixing points disperse tension uniformly, effectively prevent hole tearing on aluminum, iron and plastic plates, installation firmness far exceeds 4-hole small hinges.

4. 180° Full Flat Opening Function

Unrestricted 180-degree flip design enables the door panel to lay completely flat against the cabinet side, fully exposing the internal space. It brings maximum convenience for wiring overhaul, component replacement, equipment debugging and daily maintenance, no obstruction during operation.

Core Selling Points

1. Rustproof Stainless Steel Body Adaptable to humid, workshop and semi-outdoor working conditions, long service life.
2. Wire Brushed Anti-Fingerprint Surface Anti-scratch, easy to clean, keeps industrial aesthetic for years.
3. 3mm Thickened Heavy-Duty Plate Strong load-bearing capacity, anti-deformation for medium weight cabinet doors.
4. 8-Hole Flush Hidden Mounting Stress evenly distributed, screw concealed installation, neat equipment exterior.
5. 180° Full Flat Unobstructed Opening Max access to internal components, greatly simplify maintenance work.

Main Application Scenarios

1. Outdoor waterproof electrical distribution boxes, inverter enclosures and communication terminal cabinets
2. Industrial automation equipment protective doors, CNC machine tool auxiliary access panels
3. Laboratory testing instruments, medical equipment casings and precision test boxes
4. Aluminum alloy equipment chassis, server side panels and control operation boxes
5. Marine mild corrosion equipment housings, outdoor advertising cabinet flip doors

Installation & Selection Notes

1. Load Range: Suitable for medium-weight door panels; for ultra-heavy large doors, use two sets of CL158-2 hinges for balanced bearing.
2. Screw Matching: Must use 90° countersunk flat head screws matching Φ12.8 sink holes to realize fully flush installation.
3. Opening Feature: This model can open flat to 180°, confirm space clearance on cabinet side before bulk order to avoid collision.
4. Maintenance Tip: Regularly add lubricant to the Φ10 central pivot pin to keep rotation smooth and silent.
