Product overview

Core functionalities

Applicable scenarios

Unique advantages

Frame Connection & Structural Support: Designed to securely connect 20-series aluminum profiles into robust frameworks, providing stable joints for furniture, machinery, or display systems.
Arc End Cushioning: The rubber-like cover cap (black component) reduces vibration, prevents scratches, and ensures smooth transitions at corners, enhancing durability and user safety.

Key features

1. Corrosion-Resistant Zinc-Plated Aluminum Construction

With zinc-plated aluminum and a durable rubber cover cap, you can ensure long-lasting durability in humid or corrosive environments. Outperforms standard brackets by resisting corrosion 3x longer in harsh conditions.

2. Pre-Drilled Triangular Design for Quick Assembly

With pre-drilled triangular holes and snap-fit cover caps, you can assemble frames 40% faster than traditional brackets. Reduces installation time compared to non-pre-drilled designs.

3. High Load-Bearing Capacity for Heavy-Duty Use

With a 50kg load capacity, you can support robust structures in industrial or commercial applications. 50% higher load-bearing capability than plastic alternatives.

4. Versatile 3-Way Arc Design for Multi-Scenario Use

With a 3-way arc configuration, you can adapt to both home DIY projects and commercial framing systems. Ideal for continuous operation in commercial settings versus one-time home setups.

5. ISO 9001 Certified for Quality Assurance

With ISO 9001 certification, you can trust reliable performance and safety compliance. Meets international standards for industrial components.
