Description
Product Name: Stainless Steel L-Shaped 2040 Profile Corner Bracket
Purpose: Connects 2040 aluminum extrusion profiles at a rigid 90° angle to build frames, enclosures, machines, and other modular structures.
Core Function:
- Facilitates right-angle joints between two perpendicular 2040 (20mm × 40mm) aluminum profiles.
- Provides mechanical strength, stability, and alignment for modular framing systems.
Typical Specifications
Compatibility
- Designed for 2040 series aluminum extrusion profiles with a 20mm × 40mm cross-section.
- Compatible with standard T-slot and V-slot profile systems used in industrial framing, robotics, CNC machines, 3D printers, and DIY builds.
Material
- Stainless Steel body, with common grades including AISI 304 or AISI 316, depending on the supplier.
- Stainless steel construction provides good corrosion resistance and durability compared with typical mild steel or aluminum brackets.
Physical Dimensions (approximate & dependent on supplier)
- Bracket leg lengths are designed to accommodate the profile dimensions and provide secure engagement.
- Bracketing surfaces are typically sized to suit the 2040 profile geometry, with one side approximately matching the 40mm profile height.
- Thickness and overall dimensions may vary by manufacturer. Refer to the specific product dimensions for precise measurements.
Fastening Interface
- Pre-drilled or machined bolt holes designed for compatible extrusion-slot hardware.
- Commonly used with M5 screws and T-nuts, depending on the profile and fastening system.
- Hole spacing and thread compatibility depend on the specific bracket design.
Finish
- Natural stainless steel or passivated finish for improved corrosion resistance.
- Available color options may include Black, Blue, Green, Orange, Red, Silver, White, and Yellow.
Features
Structural and Mechanical
- 90° Right-Angle Joint: Provides a strong corner connection for assembling rigid frames and structures.
- High Strength: Stainless steel construction offers good strength and durability for applications requiring reliable structural support and vibration resistance.
Corrosion Resistance
- Stainless steel construction helps resist rust and oxidation, making the bracket suitable for humid, outdoor, laboratory, and other demanding environments.
Modular Assembly
- Works with standard T-slot / V-slot extrusion hardware, including compatible T-nuts and socket cap screws.
- Allows repeatable, adjustable, and reconfigurable structural connections.
Installation
- Bracket legs fit against the extrusion profiles and are secured using compatible bolts and nuts.
- Screws can typically be inserted from the outside to create a secure connection between the profiles.
Typical Applications
- Industrial Frames: Machine guards, enclosures, workbenches, automation assemblies, and structural frames.
- CNC & 3D Printing: Rigid corner joints for CNC machine, router, and 3D printer frames.
- Robotics & Automation: Structural support for robotic arms, conveyors, fixtures, and automation equipment.
- Custom Equipment: Workstations, shelving, fixtures, and other structures requiring strong and corrosion-resistant joints.
Performance Considerations
Load Capacity
- Stainless steel brackets can provide high structural strength compared with lightweight aluminum brackets.
- Actual load capacity depends on bracket geometry, material thickness, screw grade, profile configuration, and tightening torque.
Assembly Tips
- Use matching T-nuts and screws suitable for 2040 aluminum profiles, commonly M5 hardware.
- Ensure the profiles are properly aligned and perpendicular before fully tightening the fasteners for maximum frame rigidity.
Comparison with Standard Alloy Brackets
| Property | Standard Alloy Bracket | Stainless Steel Bracket |
|---|---|---|
| Corrosion Resistance | Moderate; may require plating or anodizing | High; stainless steel provides natural corrosion resistance |
| Strength | Good for general-purpose frames | High strength and durability |
| Weight | Lighter | Heavier |
| Suitability | Indoor and general-purpose applications | Outdoor, humid, laboratory, and demanding environments |
