Stainless Steel L-SHAPED 2020 Profile Corner Outer Bracket

Product Overview

An L-Shaped 2020 Profile Corner Bracket is a right-angle connector designed to join two pieces of 2020 series aluminum extrusion profiles (20 mm × 20 mm) at a 90° angle. It is widely used in frame structures for industrial builds, robotics, 3D printers, CNC machines, furniture, and general assembly projects.

Typical Specifications

• Compatibility: 2020 series T-slot or V-slot aluminium profiles (20 mm × 20 mm).

• Material:

  • Standard versions: Mild steel (MS) or aluminum alloy.

  • Stainless Steel versions: Made of stainless steel (e.g., AISI 304/AISI 316) for greater corrosion resistance and strength (varies by manufacturer).

• Shape: L-shaped right-angle bracket for corner joints.

• Dimensions (typical):

  • Plate size ~47.5 × 47.6 × 3 mm (Length × Width × Thickness).

  • Some designs with flanges sized ~20 × 20 × 17 mm.

• Mounting Holes:

  • Hole type: Countersunk or through-holes to accept screws and T-nuts.

  • Typical screw size: M4 (for mild steel/aluminum brackets).

• Weight: ~30 g (for smaller plate type).

Material and Finish

• Stainless Steel Material (if specified):

  • Common grades: AISI 304 or AISI 316 stainless steel, offering superior corrosion resistance compared with mild steel or plain aluminum alloy.

  • Finish: Natural/brush or passivated (for corrosion protection).

• Alternatives: Mild steel or aluminum alloy versions are also common; stainless steel is preferred in environments where rust resistance and cleanliness are critical.

Features

• Right-Angle Connection: Provides a secure 90° joint between two 2020 profiles.

• Robust and Durable: Designed for repeated assembly/disassembly without deformation.

• Easy Installation: Fits into profile T-slots; fastens with screws and T-nuts; no drilling required.

• High Strength Joint: Capable of reinforcing structural corners in light to medium load frames.

• Versatile Use Cases:

  • Industrial framing systems

  • CNC machines

  • 3D printers

  • Robotics or automation assemblies

  • Furniture seating or shelving frames

  • Workstations and display structures.

Typical Installation Notes

• Insert bracket legs into the T-slots of the two profiles at the corner.

• Use screws with compatible T-nuts inside the profile channels.

• Tighten screws evenly to achieve a square connection.

• For heavier loads or milled-face brackets, ensure multiple fasteners per profile leg.

Variants and Options

• Plate-style L brackets: Flat plates with mounting holes (lighter duty).

• Solid L blocks: Solid L-shaped blocks, sometimes anodized or die-cast (higher rigidity).

• With Hardware Kits: Some sets include screws, T-nuts, and washers for complete installation.
